GPS sensor. To get the latest firmware, refer to "Upgrading the Soft- ware/Firmware" on page 131. A Bird Electronic Compact GPS Sensor can be connected to the COM1 serial port located on the back panel. It is used to record geographic position information associated with a trace.
Chapter 2 Vector Network Analyzer Settings The proper settings are very important for the most accurate information possi- ble. The SignalHawk can be configured in various ways, allowing for a wide range of measurement capabilities. Core Soft Key Functions “Soft Keys” serve multiple functions on the SignalHawk. There are four core functions: On/Off Button - Push to toggle the corresponding function on or off.
Freq & Span Menu Figure 14 Freq & Span Menu In the Freq & Span Menu, the range of frequencies to sweep are specified. Frequencies can be selected at spans from 1 kHz up to the entire range of the instrument.
Start / Stop Freq and Center / Span These settings control the frequency range being swept. Note: “Center / Span” are used in this manual, but using “Start / Stop Freq” achieves the same results. After pressing the soft key, it will highlight the active function. Then the following can be performed: ...
Calibrate Menu Ensure that the calibration is done properly. For the best results, use a Bird cali- bration kit. If calibration is not done properly, the readings from the VNA will be wrong. Note: Set any parameters that the calibration may depend on BEFORE starting the calibration of the unit.
Page 50
Note: If the unit is operating without valid calibration, the text in the cal area of the status bar will be red and say “Off”. If it has a calibration, the calibration method will be listed in black text. Note: For most isolation and gain measurements, only a thru cal (Cable from RF Out-In) is needed.
Ampt & Trace Menu Figure 17 Example, Ampt & Trace Menu Autoscale Resizes the graph to fit the whole trace on the screen. This function will change the reference and scale of a trace. Max Level Sets the upper limit of the vertical axis. Min Level Sets the lower limit of the vertical axis.
If there are fewer points than screen pixels, the unit will interpolate between them. Note: Once the unit is calibrated, reducing the number of points below 1409 does not require recalibration. If there are more points, the unit will draw multiple data points in each column.
Water Fall The Water Fall is a spectrogram that shows how the spectral density of a signal varies with time and presents it in a visual image. The Water Fall display is used to identify intermittent interference. Power is lin- early mapped to graph display color.
Mark & Limit Menu Figure 20 Example, Mark & Limit Menu Select Marker Changes the active marker. There are six markers to choose from. Pressing the soft key will cycle through each of the six markers. Marker On / Off Turns the Marker on and off.
Threshold Offset Raises a signal above the noise floor. This filters out low level peaks allowing for a clear reading. Marker to Max Peak or Marker to Min Valley Sets the marker to either the maximum peak or minimum valley depending on the functionality chosen in Markers Detect.
Marker More Sets the properties of active markers through the following attributes: RSSI (Received Signal Strength Indicator) Turns the audio indicator On or Off (an electronic ping). See “Received Signal Strength Indicator (RSSI)” on page 92. Volume Sets the volume of the electronic ping generated from the RSSI. Marker Freq to Center Moves the current marker to the center frequency.
File & Help Menu Figure 21 Example, File & Help Menu Quick Save Saves the trace that is displayed on the screen. To save the trace: 1. Press the File & Help menu key 2. Press the Quick Save Trace soft key. The trace is stored as a file in the internal memory of the instrument.

Chapter 3 Vector Network Analyzer Measurements In the Vector Network Analyzer mode, the following measurements can be made: "Match Measurement" on page 42. "Distance to Fault (DTF) Measurement" on page 46. "Cable Loss (1 Port) Measurement" on page 54. ...
Match Measurement This measurement displays how well matched a system is to a 50 ohm character- istic impedance. Return loss is a measure of impedance mismatch between two or more circuits. The SignalHawk can calculate the system match as VSWR, Return Loss, Reflec- tion Coefficient, Match Efficiency % and Reflection %.

Distance to Fault (DTF) Measurement This measurement will display the distance to a fault in a given length of cable. The standard settings for this measurement are Start & Stop Distances, Distance Units, Cable Velocity Propagation & Loss, and Smoothing. These settings can be adjusted using either the thumbwheel or keypad.
Figure 31 Example, Distance-to-Fault Measurement Settings Start Distance Sets the starting distance for a measurement within the cable system. Figure 32 Example, Distance-to-Fault - Start Distance Setting Setting...
Stop Distance Sets the stop distance for a measurement within the cable system. Note: Set the Stop Distance to a value that is a few feet or meters greater than the entire length of the cable system to avoid aliasing. Figure 33 Example, Distance-to-Fault - Stop Distance Setting Setting...
Cable List Select a specific cable from a list. Note: Custom cables can be added to the list. See “Customizing Sig- nalHawk Content” on page 129. Figure 34 Example, Distance-to-Fault - Cable Setting - Cable List Settings Velocity Sets the speed of the signal going through the cable being measured. Note: Changing this setting cancels any selection on the Cable List and changes that setting to “None.”...
Loss Applies an offset to compensate for cable loss. Note: Changing this setting cancels any selection on the Cable List and changes that setting to “None.” Figure 36 Example, Distance-to-Fault - Cable Setting - Cable Loss Settings Smooth Smoothes the trace line on the display. It can be set to one of four tolerances: None, Low, Medium, and High.
DTF Wizard Note: Maximum allowed distance and resolution per point is a com- plex function of the cable and frequency settings. Use the DTF wizard if the SignalHawk is having issues resolving these functions. When the DTF Wizard soft key is pressed, a window with a set of adjustable vari- ables will open in the display.
Loss Offsets the signal to compensate for cable loss. Using the soft keys, this can be set in either dB/m or dB/ft. Note: The wizard will automatically apply velocity and loss to their fields. Figure 39 Example, Distance-to-Fault - DTF Wizard - Loss Settings Estimated Cable Sets the length or, if length is unknown, the estimated length of the cable being tested.
Center Frequency Sets the center frequency of the trace to allow for the most accurate reading as possible, whether testing antennas, filters and the like. Using the soft keys, this can be set in Hz, kHz, MHz, and GHz. Figure 41 Example, Distance-to-Fault - DTF Wizard - Center Frequency Settings Preferred Resolution Sets the desired resolution, or distance each pixel of the display...
(not connected to anything at the far end). 1. Ensure that the correct adapters, connectors, and a Bird Calibration Combi- nation (cal combo) are used. The frequency band of the system will also be needed.
Gain & Loss (2 Port) Measurement This two-port thru measurement is used to test the insertion gain and loss of a cable. To run this measurement, connect the transmitter of the device being tested to Port 1 and the receiver of the device to Port 2. Transmission loss or gain will be negative if the device has a loss and positive if the device has a gain.
Chapter 4 Spectrum Analyzer Settings The use of proper settings is very important for obtaining the most accurate information possible. The SignalHawk can be configured in various ways, allow- ing for a wide range of measurement capabilities. Core Soft Key Functions “Soft Keys”...
Freq & Span Menu Figure 45 Freq & Span Menu In the Freq & Span Menu, the range of frequencies to be tested is specified. The Spectrum Analyzer can sweep frequencies between 100 kHz and 3.6 GHz. Frequencies can be selected at spans from 1 kHz up to the entire range of the instrument.
Start / Stop Freq and Center / Span These settings control the frequency range being swept. Note: “Center / Span” are used in this manual, but using “Start / Stop Freq” achieves the same results. When the soft key is pressed, the corresponding selection is highlighted. The fol- lowing can then be performed: ...
Note: Channelized bands are denoted on the Frequency List by a plus sign (+). Adding Custom Frequencies See “Customizing SignalHawk Content” on page 129. Figure 46 Example, Freq List Recently Used Bands...
BW & Sweep Menu The bandwidth menu includes functions that control sweep speed and accuracy. It can also customize sweep triggers. When two signals are separated by a freq distance equal to the Resolution BW (RBW), a 3 dB dip between them will appear on the screen. This is the minimum resolvable frequency spacing.
RBW goes from 100 Hz - 1 MHz in steps of 1 / 3 / 10 (e.g., 1 kHz to 3 kHz to 10 kHz to 30 kHz, etc.) Video Bandwidth (VBW) determines how much smoothing is performed on a video converted signal before the trace is displayed.
Auto VBW sets the VBW based upon the RBW value. When in Auto mode, the VBW is set according to the nearest ratio as set using the VBW/RBW selection. The default ratio is 3. As the RBW span is reduced the VBW will be reduced accordingly.
Figure 49 Example, RBW/VBW Detection Mode Depending on measurement settings, more data points are collected than there are pixels on the screen. Detection modes allow the user to choose how the col- lected data in each pixel is represented. + Peak Detection Returns the maximum value of the data collected for each display pixel.
Figure 50 Example, Detection Mode Sweep More Sweep sets up the properties of individual sweeps that the SignalHawk per- forms. It can set whether the sweeping is continuous or single, and the properties of video triggers (if enabled). Continuous Sweeps the measurement span continuously. Free Rep - Figure 51 Example, Sweep More - Continuous Sweep...
Single Performs a single sweep. Before a single sweep is triggered, the SignalHawk will display the previous sweep. To begin a sweep, press the Manual Trigger soft key. After the sweep finishes, it will display the results and stop sweeping. Sets the type of trigger that initiates a sweep.

Figure 54 Example, Low Level / High Level / Rise Edge / Fall Edge / Either Edge Video Note: This can only be used if the Time Domain measurement is enabled. See “Time Domain (Zero Span)” on page 91. Trigger control and sweeping both happen on the radio frequency connector.
Ampt & Trace Menu Figure 56 Example, Ampt & Trace Menu Autoscale Resizes the graph to fit the whole trace on the screen. This function changes the reference and scale of a trace. Reference Sets the y-axis value at the top of the graph. Scale Sets the dB value of each partition of the graph on a scale from 1 to 15.
Preamp Controls the built-in amplifier on the signal input. This lowers the noise floor, allowing very low power signals be detected, by giving a 24 dB nominal gain boost. Note: Attenuation is automatically disabled to 0 when Preamp is activated. Note: The preamp should not be used with input signals greater than -30 dBm.
Trace Opens a trace submenu with the following options: Clear Write Switches off the Average and Max Hold functions. Max Hold Holds and displays the highest point of any given sweep until Max Hold is turned off. Min Hold Holds and displays the lowest point of any given sweep until Min Hold is turned off.
Mark & Limit Menu Figure 57 Example, Mark & Limit Menu Select Marker Changes the active marker. There are six markers to choose from (measurements that use some of the markers for data display have less selectable markers). Pressing the soft key will cycle through each of the six markers. Marker On / Off Turns a Marker on and off.
Marker to Max Peak or Marker to Min Valley Sets the marker to the either the maximum peak or minimum valley depending on the functionality chosen in Markers Detect. See “Markers Detect” on page 73. Marker to Next Peak Left or Marker to Next Valley Left Cycles the active marker to the left through the points on the trace either from highest peaks or lowest valleys (see “Markers Detect”...
RSSI (Received Signal Strength Indicator) Turns the audio indicator On or Off (an electronic ping). See “Received Signal Strength Indicator (RSSI)” on page 92. Volume Sets the volume of the electronic ping generated from the RSSI. Marker Freq to Center Moves the current marker to the center frequency.
Figure 58 Example, Mask List Once a mask is selected, it is controlled by the following options: Locks the mask onto the selected band even if the Freq Lock - frequency is changed. Sets mask’s reference level to the maximum peak in each EM to Max Peak - sweep.
File & Help Menu When the File & Help menu key is pressed, soft keys for saving the current trace, selecting the utility option, activating the logging feature, and accessing help features are enabled. A trace is saved as a file and stored in the internal memory of the instrument.
Label & Save Trace Labels and saves the trace for future use. 1. Press the Save Trace soft key. 2. Enter a file name using the thumbwheel and arrow keys. Note: Use the Up-and-down arrow keys to move vertically and the wheel to move horizontally along the Input Panel.

Note: The DTF section of the VNA help is also accessible in the DTF measurement screen.
Chapter 5 Spectrum Analyzer Measurements Spectrum Analysis, measuring the power at each frequency in the sweep range, is the basic measurement. The other measurements interpret that data to pro- vide useful results. In the Spectrum Analyzer mode, the following measurements can be used: ...
Spectrum Analysis Measurement Spectrum Analysis graphically displays signal amplitude at each frequency in the range shown on the screen. Figure 67 Example, Spectrum Analysis, Frequency and Span Screen...
Occupied Bandwidth Measurement Occupied Bandwidth measures the frequency band bandwidth that contains a specified percentage of the total power of the signal. It gives best results with single-peaked signals. Bandwidth can be defined in two ways. Both give measurement results in Hz units. Threshold Modes The calculated occupied bandwidth represents the user specified percent of the total power of the displayed span.
Page 108
Figure 69 Example, Occupied Bandwidth - % STEP 1 STEP 2 Note: The limit can be set without changing the Threshold Mode. Figure 70 Example, Occupied Bandwidth - dBc STEP 1 STEP 2 Note: The limit can be set without changing the Threshold Mode.
Channel Power Measurement Channel Power measures the Integration Bandwidth, the total power over a fre- quency range, concentrated on the center frequency of the sweep. It is useful for channelized (frequency-division multiplexed) signals. Results are shown in both total power in the channel (in dBm or Watts), and spectral density (dBm or Watts per Hz).
Adjacent Channel Power Measurement Adjacent Channel Power measures the relative power of frequency bands adjacent to a central channel. This is often used to identify power leakage from the center channel into the adjacent channels. The total power in the central (main) channel is displayed in dBm (Ch Power), and the power in the adjacent channels is displayed as dB below and above the main channel power (Dn ACPR and Up ACPR).
Time Domain (Zero Span) In Time Domain, the amplitude of a single frequency is measured, rather than sweeping a range of frequencies. The SignalHawk measures and displays the ampli- tude of the frequency for a specified period (sweep time) and refreshes during the next sweep.
Field Strength Measurement Field Strength measures the signals reaching an antenna. The SignalHawk automatically corrects the sweep data for the antenna’s gain and frequency dependence and displays it in dBm / m. 1. Connect an antenna connected to the RF In connector on the SignalHawk.
Demodulate Signal Removes the carrier and sends the signal to the internal speaker or head- phones. The SignalHawk can demodulate AM, narrowband FM, and wideband FM signals. It can also set the specific frequency and volume. 1. Set the type of demodulation: a.
Carrier-to-Interference Ratio Calculates the ratio of the carrier signal power to the power level of the noise and interference signals. To determine the ratio, two measurements need be done. First sweep should be the carrier and interferer. The second sweep should be the interferer alone. Note: Because the transmitted carrier must be turned off for the sec- ond portion of this measurement, access to the transmitter is needed to complete this procedure.
Page 117
