Page 43 Analyzer Precision components required for calibration and performance verification. Optional use of ANRITSU 67XXB, 68XXXA/B/C, or 69XXXA/B as a second source. The 37XXXC internal system modules perform the following functions: Source Module This module provides the stimulus to the device under test (DUT). The frequency range of the source and test set modules establish the fre- quency range of the system.
Page 44 There are several different ways to per- detection form the measurement. The method ANRITSU employs (called Har- monic Sampling or Harmonic Mixing) is to down-convert the signal to a lower intermediate frequency (IF). This signal can then be measured directly by a tuned receiver.
Page 45 NETWORK ANALYZERS NETWORK ANALYZERS, A PRIMER Vector Network Analyzer Basics The network analyzer is a tuned receiver (Figure 3-4, left). The micro- A NETWORK ANALYZER IS A TUNED RECEIVER wave signal is down converted into the passband of the IF. To measure the phase of this signal, we must have a reference to compare it with.
Page 46 NETWORK ANALYZERS, A PRIMER NETWORK ANALYZERS Assume that we are making a measurement at 1 GHz and that the dif- ference in path-length between the two signals is exactly 1 wave- length. This means that test signal is lagging the reference signal by REFERENCE TEST 360 degrees (Figure 3-8).
Page 47 NETWORK ANALYZERS NETWORK ANALYZERS, A PRIMER There are two ways of accomplishing this. The most obvious way is to insert a length of line into the reference signal path to make both paths of equal length (Figure 3-11, below). With perfect transmission lines and a perfect splitter, we would then measure a constant phase as we change the frequency.
Page 48 NETWORK ANALYZERS, A PRIMER NETWORK ANALYZERS Network Analyzer Measurements Now let us consider measuring the DUT. Consider a two port device; that is, a device with a connector on each end. What measurements would be of interest PORT 1 PORT 2 First, we could measure the reflection characteristics at either end FORWARD REVERSE...
Page 49 NETWORK ANALYZERS NETWORK ANALYZERS, A PRIMER There are several ways in which all the information can be displayed POLAR DISPLAY on one trace. One method is a polar display (Figure 3-17). The radial parameter (distance from the center) is magnitude. The rotation around the circle is phase.
Page 50 NETWORK ANALYZERS, A PRIMER NETWORK ANALYZERS Another important parameter we can measure when phase informa- tion is available is group delay. In linear devices, the phase change through the DUT is linear-with-frequency. Thus, doubling the fre- quency also doubles the phase change. An important measurement, es- pecially for communications system users, is the rate of change-of-phase-vs.-frequency (group delay).

Page 120 Chapter 7 Measurement Calibration INTRODUCTION This section provides discussion and examples for performing a mea- surement calibration. It also provides a detailed procedure for calibrat- ing with a sliding termination. Measurements always include a degree of uncertainty due to imperfec- DISCUSSION tions in the measurement system.
Page 121 Many calibration kits include adapters that are designed to have equal phase length. These parts are called phase equal adapters (PEA). Anritsu designs in-series adapters (e.g., K Connector M-M, M-F, F-F) to be phase insertable when technically possible. When available, it is good practice to use PEAs to establish test ports (Figure 7-3).
Page 122 MEASUREMENT CALIBRATION DISCUSSION This approach offers two advantages: It minimizes wear on the more expensive test set and cable con- nectors. It provides a simple solution to measuring non-insertable devices (e.g., a filter with K female input and output connectors), by merely swapping PEAs after calibration.
Page 123 DISCUSSION MEASUREMENT CALIBRATION ables are not completely correctable. However, some of them can be minimized by careful control. For instance: temperature effects can be reduced by room temperature control, calibration variables can be re- ERRORS REDUCED BY CALIBRATION duced through improved technique and training, and frequency errors can be virtually eliminated by the fully synthesized internal source.

Page 126 MEASUREMENT CALIBRATION DISCUSSION Calibrating for a Let us assume that we want to correct for three errors in the reflection Measurement measurement: source match, directivity, and tracking. We accomplish this using three standards. Shorts are the easiest to visualize. They totally reflect all of the inci- dent RF energy output at a precise phase.

Page 128 The best way to confirm a calibration is to measure a precision, known-good device and confirm its specifications. Verification Kits ANRITSU has developed several precision-component kits: for 3.5 mm connectors, for GPC-7 connectors, K Connectorsâ and V Connectorsâ. These are, respectively, the Models 3666, 3667, and 3668 and 3669 Verification Kits.
Page 129 DISCUSSION MEASUREMENT CALIBRATION vorably with the recorded data (taking tolerances into consideration), then the system is known to be operating properly and providing accu- rate data. There is one caution that you need to observe when using Verification Kits. Because the verification components have been characterized, you must handle them carefully so that you do not change their known characteristics.
Page 130 MEASUREMENT CALIBRATION SLIDING TERMINATION SLIDING TERMINATION Sliding terminations (loads) are the traditional Z calibra- tion-reference devices for vector network analyzer calibration. When correctly used and perfectly aligned, they can be more accurate than precision fixed loads. However, sliding terminations have a 2 GHz (4 GHz for V-Connector sliding loads) low-frequency limit and must be used with a fixed load for full frequency-range coverage.

Instead of using the standard Open, Short, and Load, the LRL/LRM calibration method uses two lines and a reflection or match. The difference in length between line 1 and line 2 creates the mea- surements necessary for the error solutions.

Calibra- (Coaxial) tion kits for GPC-7 are available from Maury Microwave and Hewlett Packard. Two line lengths are used as the impedance standard. The calibration frequency range is limited by the difference in the lengths of the two lines.
Page 158 MEASUREMENT CALIBRATION LRL/LRM CALIBRATION Consideration must also be given to selecting the breakpoint frequency.

Page 172 LOW LEVEL AND GAIN MEASUREMENTS LOW LEVEL AND GAIN This discussion provides methods and techniques for making gain and low-signal-level measurements. It is divided into 37XXXC system con- siderations and test device considerations. 37XXXC System Considerations The 37XXXC system is limited in its ability to test low-signal levels by its dynamic range and signal-to-noise-power ratio.
Page 173 MEASUREMENTS LOW LEVEL AND GAIN The detected signal is the vector sum of the desired signals, the noise signals, and the leakage signals. These signals introduce an error or uncertainty (Figure 8-8). Figure 8-8. Amplitude and Phase Uncertainty LEAKAGE PATHS Some of the possible leakage paths for the 37XXXC are the transfer Transfer Switch (120 db) switch, the frequency conversion module, and the DUT.

Page 175 MEASUREMENTS LOW LEVEL AND GAIN The most difficult types of measurements are those that exercise the full dynamic range of the 37XXXC, such as filters (Figure 8-). Filter measurements are examples of where one must observe both low-insertion loss (in the passband) and high attenuation (in the stop band).
Page 176 LOW LEVEL AND GAIN MEASUREMENTS Averaging is another way to improve accuracy. The improvement is proportional to the square root of the number of averages. The im- AVERAGING provement from averaging, however, comes at the expense of increased Up to 4096 Averages sweep time.
Page 177 MEASUREMENTS LOW LEVEL AND GAIN Test Device (DUT) Considerations In order to test a device, the required input RF level and the expected device output RF level must be determined. The RF level at Port 1 must be set for the device input RF power level PORT 1 RF OUTPUT LEVEL required.

Page 180 GROUP DELAY MEASUREMENTS GROUP DELAY Group delay is the measure of transit time through a device at a par- ticular frequency. Ideally, we want to measure a constant—or rela- tively constant—transit time over frequency. The top waveform shown in Figure 8-13 is measured at one frequency. The bottom waveform is identical to the first, simply delayed in time.
Page 181 MEASUREMENTS GROUP DELAY When designing components it is important to measure group delay so GROUP DELAY that you can compensate for any distortion caused by the component. Measure During Design You may be able to tune the device so as to optimize the performance of group delay over the frequency range of interest.
Page 182 GROUP DELAY MEASUREMENTS at a group delay measurement made on the ANRITSU 37347C Vector Network Analyzer. Group delay, as a measurement option, can be found in the Graph Type menu. After selecting the option, the VNA displays the data in a time-vs-frequency graph, or to be more exact, a group-delay-vs-frequency graph (Figure 8-16).
Page 183 MEASUREMENTS GROUP DELAY The aperture defaults to the smallest setting for the frequency range and number of data points selected. This value is displayed in the Set Scale key menu when measuring group delay (Figure 8-18). Figure 8-18. 37XXXC Aperture Group delay applications are found throughout the microwave indus- try, although the majority of such measurements are made in the tele- communications area.
Page 184 ACTIVE DEVICE MEASUREMENTS ACTIVE DEVICE Active devices are key components in microwave systems. The measurements that are made on active devices are similar to those made on passive devices. Active devices come in many shapes and sizes. In most cases we are going to have to develop a fixture in which to mount the device.
Page 185 MEASUREMENTS ACTIVE DEVICE Figure 8-20. Active Device Test Fixture Now we have an interesting situation. While we can measure the per- formance at the connector— which is the calibration plane— what we really want to know is how our device performs (Figure 8-21). Figure 8-21.
Page 186 ACTIVE DEVICE MEASUREMENTS Figure 8-22. Simple Example of De-Embedding In some cases—depending on the fixture or the device being meas- ured—this is satisfactory. But when it is not, we need to employ other techniques. One of the reasons that moving the reference plane out to the device does not always work, is that the test fixture includes a transition from coax to a structure such as microstrip, coplanar waveguide, or stripline (Figure 8-23).

Page 224 Chapter 9 Time Domain INTRODUCTION This chapter describes the optional Time Domain feature. TIME DOMAIN The Option 2, Time Domain feature provides a useful measurement MEASUREMENTS tool for determining the location of impedance discontinuities. Some typical applications are identifying and analyzing circuit elements, iso- lating and analyzing a desired response, locating faults in cables, and measuring antennas.
Page 225 TIME DOMAIN MEASUREMENTS TIME DOMAIN The lowpass impulse response displays the location of discontinuities as well as information useful in determining the impedance (R, L, or Used When Device Has a DC or C) of each discontinuity. Low Frequency Path The impulse response is a peak that goes positive for R>Z and nega- tive for R<Z...

Location of Discontinuities The lowpass step response for a resistive impedance is a positive level Information on Type of Discontinui- shift for R>Z and a negative level shift for R<Z .

Unlike the lowpass mode, no information as to the type of the disconti- Calculates Impulse or nuity is available.
Page 228 TIME DOMAIN TIME DOMAIN MEASUREMENTS Figure 9-7. Complex Impedances Next, let us look at a complex circuit. A resistive impedance change R<Z and a shunt capacitance and series inductance. These impedance changes are shown in the time domain for the lowpass-impulse re- sponse, lowpass-step response, and bandpass-impulse response (Fig- ure 9-8).

Page 232 TIME DOMAIN WINDOWING WINDOWING Windowing is a frequency filter that we apply to the frequency-domain data when we convert it to time-domain data. This filtering rolls off the abrupt transition at F1 and F2. This effectively produces a time- domain response with lower sidelobes. Windowing allows a limited de- gree of control over the pulse shape, trading off ringing (sidelobes) for pulse width (Figure 9-15).
Page 233 GATING TIME DOMAIN GATING Gating is a time filter that allows for removing unwanted time-domain responses by gating the desired response. We can view the isolated re- sponse in both time domain—and in the frequency domain—using the FREQUENCY WITH TIME GATE selection (Figure 9-17). There are four different gate shapes available: MINIMUM, NOMI- NAL, WIDE, and MAXIMUM (Figure 9-18).
Page 234 TIME DOMAIN GATING An informational message will be displayed in the data area when the window or gate shape reset in this way. The message will last 2 sweeps, and will say: “GATE SHAPE ADJUSTED” or “WINDOW SHAPE ADJUSTED” depending on which was changed by the software. Figure 9-18A.
Page 235 ANTI-GATING TIME DOMAIN ANTI-GATING Anti-gating is the opposite of gating. Whereby, gating provides for re- moving all but the desired response, anti-gating displays all but the desired response. To provide anti-gating, gate in the normal manner, except use a minus value for the SPAN width (middle left menu on next page).

Page 246 CALIBRATIONS AUTOCAL 10-3 Four types of calibration can be performed using AutoCal: CALIBRATIONS One-Port: S11 1-Port and S22 1-Port are 1-port calibrations per- formed on the indicated port of the VNA and are equivalent to the tra- ditional Open-Short-Load calibrations. Full 2-Port: This type is equivalent to the traditional Open-Short-Load-Thru (OSLT) calibration.
Page 247 AUTOCAL DEFINITION step is required to characterize the leakage of the VNA and test setup. The isolation step can be performed automatically as part of a “Full 2-Port” calibration when using the mechanical module. The isolation step requires a manual operation for the electronic module. In order to achieve high accuracy for the characterization of the leakage, a high averaging factor is needed.
Page 248 PHYSICAL SETUP AUTOCAL 10-5 See Figure 10-2 for an illustration of the connections necessary to per- PHYSICAL SETUP form an automatic calibration using the AutoCal module. Note that the connection is very simple. Different power cable connectors are used with the mechanical modules and the electronic modules to pre- vent connecting the wrong power supply in error.
