Page 57: Measuring Devices With Your Network Analyzer
This section provides a basic overview of how the network analyzer measures devices. The analyzer has an RF signal source that produces an incident signal that is used as a stimulus to the device under test. Your device responds by reflecting a portion of the incident signal and transmitting (or perhaps altering and transmitting) the remaining signal.
Page 58 Making Measurements Measuring Devices with Your Network Analyzer Refer to Figure 3-2 for the following discussion regarding detection schemes and modes. The transmitted signal (routed to input B) and the reflected signal (input A) are measured by comparison to the incident signal. The network analyzer couples off a small portion of the incident signal to use as a reference signal (routed to input R).

Page 131: Using Limit Testing
Limit testing is a measurement technique that compares measurement data to constraints that you dehne. Depending on the results of this comparison, the analyzer can indicate if your device either passes or fails the test. Limit testing is useful for real-time tuning of devices to speciEcations. When limit testing is turned on, pass/fail results can be output to the display and also to the LIMIT TEST TTL IN/OUT connector on the rear panel.

Page 143: To Use Relative Limits
Using Instrument Functions Using limit Testing There may be times when you are interested in the shape of a measurement trace, but not concerned with the absolute amplitude. For example, Figure 4-16 shows limit lines created for tuning a filter to a particular shape. If the shape is more important than the amplitude, you can make the limit lines relative to the peak point of the trace using the reference tracking function.

The values entered for stimulus and amplitude are unitless. If the C A U T I O N measurement format is changed after limit lines are set, the amplitude values do not automatically change.
Page 147 Using Instrument Functions Using limit Testing Example 1. When using a small number of measurement points, limit lines must be set carefully, or the results may be confusing, because the analyzer connects the measurement points with straight lines. The following illustration shows a data trace with three measurement points: A, B, and C, along with a minimum limit line.
Page 148 Using Instrument Functions Using limit Testing Example 2. In this example, the analyzer has been set up with the following parameters: Start frequency = 90 MHz Stop frequency = 210 MHz Number of points = 11 Maximum limit line begin frequency = 90 MHz Maximum limit line end frequency = 200 MHz Refer to the illustration below for the discussion.
Page 149: Using Reference Tracking

Page 205: Increasing Sweep Speed
(HP 87136 only) Since the analyzer sweeps frequencies below approximately 20 MHz at a slower rate, you can increase the start frequency to speed up the sweep.
Page 206: To Set The Sweep Time To Auto Mode
Optimizing Measurements Increasing Sweep Speed Auto sweep time mode (the preset instrument mode), maintains the fastest sweep speed possible for any particular measurement settings. When AUTO is all capital letters, it indicates that the analyzer is in auto sweep time mode. If MAN is all capital letters, the analyzer is in manual sweep time mode.
Page 207: To Reduce The Amount Of Averaging
The following graph shows an example of the relationship between the number of points, frequency span, and sweep time. This graph was created with data from a setup on an HP 8713C using a center frequency of 1500 MHz, and a system bandwidth setting of medium.

Optimizing Measurements Increasing Sweep Speed 0 . 0 0 FREQUENCY SPAN - Figure 5-1. Relationship Between Frequency Span, Sweep Time, and Number of Points Note the following in the graph above: As the frequency span decreases, the sweep time generally decreases. As the number of points decreases, the sweep time decreases.
Page 209: To Turn Off Alternate Sweep
Optimizing Measurements Increasing Sweep Speed Alternate sweep is turned off when the analyzer is preset, but is automatically activated with some dual channel measurements. The alternate sweep feature sweeps and measures one channel at a time. By disengaging this feature, you increase the sweep speed by 50 percent. 1.
Page 210: To Turn Off Spur Avoidance
Optimizing Measurements Increasing Sweep Speed When spur avoidance is on (preset default is off), the analyzer breaks each sweep into segments. Between sweep segments, the analyzer stops and changes internal frequencies to move mixing products. Since the analyzer sweep is not interrupted when this feature is off, turn off spur avoidance to increase sweep speed.
Page 211: To Avoid Frequency Bandcrossings By Minimizing The Span (Hp 8713C Only)
Optimizing Measurements Increasing Sweep Speed Sweep time is increased when the analyzer encounters a bandcrossing point. The frequency bandcrossing points are approximately: 1900 MHz 2310 MHz 2620 MHz Press IFREQI) and then change the start frequency, stop frequency, or span to avoid sweeping through these band crossing points when possible.
Page 212: Increasing Network Analyzer Dynamic Range
Receiver dynamic range is the difference between the analyzer’s maximum allowable input level and its noise floor. For a measurement to be valid, input signals must be within these boundaries. The dynamic range is affected by two factors: input power to the device under test (DUT) You should maximize the receiver input power to achieve the highest dynamic range.
Page 213: To Reduce The Receiver Noise Floor
Optimizing Measurements Increasing Network Analyzer Dynamic Range Receiver dynamic range is the difference between the analyzer’s maximum allowable input level and its noise floor. Changing System Reducing the system bandwidth lowers the noise floor by digitally reducing the receiver input bandwidth. As system bandwidth is reduced, more receiver measurements are used per frequency point, increasing the sweep time.
Page 214 Optimizing Measurements Increasing Network Analyzer Dynamic Range Changing Measurement In averaging mode, the analyzer measures each frequency point once per Averaging sweep and averages the current and previous trace up to the averaging factor specified by the user. The instrument computes each data point based on an exponential average of consecutive sweeps weighted by the user-specsed averaging factor.
Page 215: Reducing Trace Noise
You can use three analyzer functions to help reduce the effect of noise on the data trace: reduce system bandwidth The analyzer uses a weighted running average for averaging. The noise is reduced with each new sweep as the effective averaging factor increments. 2.
Page 216: To Change System Bandwidth For Reducing Trace Noise
Optimizing Measurements Reducing Trace Noise By reducing the system bandwidth you reduce the noise that is measured during the sweep. However, the decreased bandwidth may slow down the sweep. While averaging requires multiple sweeps to reduce noise, narrowing the system bandwidth reduces the noise on each sweep. See the previous section for a more detailed explanation of system bandwidth.
Page 217 Optimizing Measurements Reducing Trace Noise Dithering to Shift Spurs Dither shifts all spurs by a small amount once, thus it imposes no sweep time penalty. But some spurs occurring within the measured frequency band may not be shifted out of band, and others may be shifted in. Therefore. dither is most effective for narrowband measurements with a user defined measurement calibration.
Page 218 Optimizing Measurements Reducing Trace Noise You will invalidate the measurement calibration if you turn spur avoid off. C A U T I O N 5-16 深圳市盛腾仪器仪表有限公司 Tel:0755-83589391 Fax:0755-83539691 Website: www.Sengt.c...
Page 219: Reducing Mismatch Errors
Mismatch errors result from differences between the DUT’s port impedance and the analyzer’s port impedance. Source match errors are produced on the source (analyzer RF OUT) side of the DUT; load match errors on the load (analyzer RF IN) side. If the DUT is not connected directly to the port, the mismatch errors due to cables, adapters, etc.
Page 220: Reducing Mismatch Errors In A Transmission Measurement
Optimizing Measurements Reducing Mismatch Errors Source match errors in transmission measurements can be reduced by performing an enhanced response calibration. (See Chapter 6.) Load match errors can be reduced by using an attenuator on the analyzer’s TRANSMISSION RF IN port. N O T E Always use high quality attenuators.
Page 221: Measuring Devices With Long Electrical Delay
When making a narrowband measurement of a device with long electrical delay, measured levels can be affected by the rate at which the source is changing frequency. This sensitivity is related to the tune required for the source signal to travel through cables or devices which are connected between the RF OUT and RF IN ports.

Page 223 Calibrating for Increased Measurement Accuracy This chapter Grst explains measurement calibration in the section titled, “Measurement Calibration Overview. II The sections following the overview provide instructions for choosing, performing, saving, and checking measurement calibrations. Each example measurement in Chapter 3 provides an example calibration for the particular type of measurement.
Page 224: Measurement Calibration Overview
Measurement calibration is a process that improves measurement accuracy by using error correction arrays to compensate for systematic measurement errors. Measurement calibration is also called cal, accuracy enhancement, and error correction. Measurement errors are classified as random, drift, and systematic errors. Random errors, such as noise and connector repeatability, are non-repeatable and not correctable by measurement calibration.
Page 225: Calibrating For Increased Measurement Accuracy Measurement Calibration Overview
Calibrating for Increased Measurement Accuracy Measurement Calibration Overview Frequency response errors (transmission and reflection tracking) are errors that are a function of frequency. Isolation errors result from energy leakage between signal paths. In transmission measurements, this leakage is due to crosstalk. In reflection measurements, it is due to imperfect directivity.
Page 226: The Calibration Reference Plane
Calibrating for Increased Measurement Accuracy Measurement Calibration Overview calibrating. Since calibration standards are very precise, great accuracy is achieved. When a user-defined calibration is performed, the analyzer compares the measurement data of known calibration standards to ideal measurement data. The network analyzer then calculates the difference between the measurement data and the calibration standard models to create error correction arrays.

Page 228: Determine If A Calibration Is Necessary
This section shows you how to determine if your measurement system requires a user-dehned calibration. Your test doesn’t require the best accuracy possible. Your test device is connected directly to the reflection port with no adapters or intervening cables. Your test device impedance matches the impedance of the analyzer. If your test setup meets these conditions, you do not need to perform any additional calibrations, however without a user-calibration, the analyzer is not guaranteed to meet its published measurement port speciiications.
Page 229: Choose An Appropriate Calibration Method
Once you have decided that it is necessary to perform a calibration, you will need to choose the calibration method suited to the type of measurement you will be performing.

IBASIC program running inside the analyzer, or be in another language running on an external computer. The control program sends SCPI and IEEE-488 commands to the analyzer’s HP-IB or LAN interface. The HP-II3 commands rapidly change the instrument settings or calibration.
Page 302 The HP-IR interface can also be used to trigger sweeps, read measurement values, or signal events within the analyzer. Most operations that can be done from the front panel can also be done over the HP-II3 interface. See the This section describes methods for changing instrument settings rapidly under program control.
Page 303: Setting The Instrument State
The analyzer offers several techniques for quickly changing the instrument’s measurement parameters: Recall of instrument states from disk The learn string HP-IB command (*LRN) SCPI commands that change specific parameters Recalling Instrument The analyzer has two built-in memory (RAM) disks, “Non-V01 RAM Disk” and States From Disk “Volatile RAM Disk”.
Page 304 Automating Measurements Automated Measurement Setup and Control Recalling a state from RAM disk typically takes 4 seconds, but the time is dependent on settings such as number of points. One strategy for managing a large set of recall states is to initially store them on a floppy disk.
Page 305 Automating Measurements Automated Measurement Setup and Control Using learn Strings to The IEEE 488 *LRN (“learn”) command can also be used to set or query a Save and Recall complete set of instrument parameters. This can be used as a programming Instrument States convenience, eliminating the need for using disk hles when saving and recalling instrument states.
Page 306: Scpi Commands That Modify A Single Parameter
Automating Measurements Automated Measurement Setup and Control If several measurement setups are similar - differing only by a few instrument parameters - the fastest way to switch between the states is for the control program to send the SCPI commands that modify those parameters.

These settings survive when the [PRESET) key is pressed, but when the analyzer’s power is cycled. Examples of volatile settings are: always returns to “HP 8711C Compatible” format after a power cycle. always returns to 0.0.0.0 after a power cycle.
Page 493: Save/Recall Memory Allocation
Before reading this section, please refer to “Saving and Recalling Measurement Results, * in Chapter 4 for an overview of the Save/Recall functions. This section provides details on the size of Save/Recall instrument state files. Since disks have limited storage capacities, it is often important to know how many instrument state Eles will Et on a disk, and how to reduce the size of each Ele in order to maximize storage.
