ATTENTION

Static Sen sitive Devices

This instrument was constructed in an ESD (electro- static discharge) protected environment. This is because mos t of the semiconductor devices used in this instrument are susceptible to damage by static discharge.

Depending on the magnitude of the charge, device substrates can be punctured or destroyed by contact or mere proximity of a static charge. The result can cause degradation of device performance, early failure, or immediate destruction.

These charges are generated in numerous ways such as simple contact, separation of materials, and normal motions of persons working with static sensitive devices.

When handling or servicing equipment containing static sensitive devices, adequate precautions must be taken to prevent device damage or destruction.

Only those who are thoroughly familiar with industry accepted techniques for handling static sensitive devices should attempt to service circuitry with these devices.

How the Test Set Averages Measurements

When the averaging function is first enabled, a numeric average is calculated and displayed each time a measurement is made. This continues until the specified number of samples is reached. From that point on, the averaging function performs an exponential filtering operation that mimics an RC filter.

Because of the exponential response, any large measurement changes result in a displayed value that ramps up or down to the actual measured value.

A measurement reset clears the measurement history for all measurements and starts the averaging process over. (Press and release the

Saving and Recalling Instrument Setups

The save and recall functions allow you to store different instrument setups and retrieve them later, eliminating the task of re-configuring the Test Set.

The number of available save registers depends on how many changes were made to th e base instrument setup for each save. (See “BASE

Settings” on page 72.) The smaller the number of changes, the greater

the number of save registers that can be used (typically over 200). Save/Recall register settings can be saved to internal RAM or to a PC

card. Saving registers to a PC card allows y ou to “back up” the settings in case you need to clear them from memory for running large programs, or when a firmware upgrade is performed (see “Memory

You can use any number, letter, or combination of numbers and letters as a name for storing instrument settings. For instance; if you want to save a setup for testing a “Vulcan7” radio, you can save the setting as “VULCAN7”.

Two register names are reserved for special purposes: POWERON and BASE.

POWERON Settings

When the Test Set is turned on, it u ses a set of instrument set u p parameters specified at the time of manufacture. You can have the instrument power up in a differe nt state by maki ng the desired changes to the original settings, and then saving them using the name POWERON.

The next time the instrument is turned on, the instrument returns to the state present when you saved t he POWERON setti ng. For inst ance; if the SCOPE screen was displa ye d whe n POWERON was saved, it is the screen that is displayed when you turn the instrument on.

Chapter 3 71

Operating Overview

Saving and Recalling Instrument Setups

BASE Settings

The BASE register contains any field settings the user has saved that are different from the instrument preset state. It establishes a reference po int for all f u tu re saves. If a base is not saved, the preset state is used as the reference.

When you save an instrument setup, the new setup is compared to the base settings, and any differences are stored under the register name you supply. Because only differences are stored, a much larger number of instrument setups can be saved than if the contents of ever y field was saved.

When you recall an instrument setting, every field is reset to the base settings. The saved settings are then used to re-establish the desired instrument setup.

You can define your own base setting. If your desired settings are very different from the preset values, you may want to change the BASE register. This will decrease the amount of memory used to save each setup, and allow you to sa ve many more setups.

CAUTION

Since each save/recall register only contains the differences between the setup being saved and the present base register settings, changing the base settings causes all other saved setups to be erased from memory (including the POWERON setting if one has been saved). Unless you consistently change the same fields to the same value each time you use the instrument, you should avoid creat ing your own BASE settings.

Memory Considerations

When the Save/Recall field of the I/O CONFIGURE screen is set to Internal, programs are saved to the same non-volatile RAM used to

create RAM disk(s) and run IBASIC programs. By saving a large number of instrument setups, you reduce the amount of RAM available to run programs. If you get a “memory overflow” message while trying to load a program, you must clear one or more save/recall registers to free RAM space.

Instrument Hardware Changes

Recalling a saved register that uses a hardware option that has been removed results in unspecified operation. Re-install the needed option before atte m pting to recal l the associ ated register( s).

Swept Gain

Measuremen t Description

This test measures the gain of a device by s weeping it over the specified frequency range. Gain is the ratio of the output power to the inpu t power. For the swept gain test, gain is measured in dB. The gain is the output power in dBm minus the input power in dBm. For exampl e, if the amplifier has an output of 22 dBm and an input of 4 dBm, it has a gain of 18 dB.

Making the Measurement

This test radiates a test signal when testing antennas or cables with antennas attached to them. Verify that the level and frequency span used for the test cannot result in i nterference to othe r nearby antennas. To minimize interference when running the program, set the power level at the DUPLEX OUT port to the minimum value needed for good measurement resolution. Set the frequency range carefully.

1. Select Swept Gain from the Select Test (Main) Menu. The Swept Gain Measurement menu will appear.

2. Position the cursor at Start Frequency in MHz and select it. Enter a value for the start of the frequency sweep from 0.4 MHz to 1000 MHz or 1700 MHz to 2000 M Hz.

3. Position the cursor at Stop frequency in MHZ and select it. Enter a value from 0.4 MHz to 1000 MHz or 1700 MHz to 2000 MHz. This value should be larger than the start frequency and in the same frequency band.

4. Position the cursor at Plot scale in dB/div and select it. A Choices menu appears. The available choices are 1, 5 or 10.

5. Position the cursor at Maximum Expected Gain in dB and select it. Enter a value in the range of − 50 to +40 dB. This parameter sets t he expected worst case power for the ANT IN port. It is very important to overestimate the expected gain to avoid damage to the ANT IN port. This parameter also determines plot resolution by setting the upper limi t.

Estimating Swept Insertion Loss Using a Single Connection

Rather than directly measuring the transmitted signal (requiring connections at both ends), a known high-quality short can be put at the end of the cable. Knowing that this will reflect 100% of the signal, the Swept Return Loss test (page 92) can be used and the measured ret urn loss in dB can simply be divided by 2 to get the system’s estimated insertion loss. If the return loss is not in dB, the square root of the measurement would be the system’s insertion loss. An open can also be used instead of a short, but the results will not be as precise.

Specifications

• Frequency Range: 0.4-1000 MHz, 1.7-2.0 GHz

• Swept Signal Level: -54 dBm to +10 dBm

• Insertion Loss Accuracy: +/- 0.75 dBm

Chapter 4 91

Overview of the Test Set’s Built-In Tools

Using the RF Tools Program

Swept Return Loss

Measuremen t Description

Swept return loss is a measure of reflection characteristics. The purpose of the swept return loss test is to detect problems in the antenna feedline system and the antenna itself. A portion of the incident power will be reflected back to the source from each transmission line fault as well as t he antenna. The ratio of the ref lected voltages to the incident voltage is called the reflection coefficient. The reflection coefficient is a complex number, meaning it has both magnitude and phase information.

The return loss is defined as the magnitude part of the reflection coefficient and is expressed in decibels (dB). Therefore, the return loss is a measure of how l arge the re flected w a ve is to the original incid e n t wave. Remember that this measurement is in terms of loss, therefore a large number means that very little signal was reflected back. A loss of 0 dB indicates that all of the incident wave is reflected, whereas a return loss of 40 dB, for example, would indicate that very little of the signal is reflected. When a device is f requency swept, a graph similar to

Figure 4-14 on page 95 is obtained. This is an example of a radio

transmitting at a particular frequency. It can be seen that the return loss at that frequency is a very large number which tapers off to small return losses at all other frequencies.

NOTE

Another way of looking at the same information is the SWR (also known as VSWR: Voltage Standing Wave Ratio). VSWR is stated as a ratio. For example: 1.2:1 or “one point two to one” VSWR. The first number in the ratio is a value between 1 and infinity. 1 indicates that none of the incident wave is reflected. Infinity implies that all of the incident wave is reflected. Therefore, the closer this number is to 1, the better the feedlin e system p erformance. The sec ond number in the r atio is always one.

Making the Measurement

When testing antennas or cables with antennas atta ched to them, a test signal is radiated. Verify that the level and frequency span used for the test cannot result in interference to other nearby systems. To minimize interference when running the program, set the power level at the DUPLEX OUT port to the minimum value needed for good measurement resolution. Set the frequency range carefully.

1. Select Swept Return Loss from the Select Test (Main) Menu. The Swept Return Loss Information menu will appear.

3. Position the cursor at Stop frequency in MHz and select it. Enter a value from 0.4 MHz to 1000 MHz or 1700 MHz to 2000 MHz. This value should be larger than the start frequency and in the same frequency band.

4. Position the cursor at Max expected loss in dB and select it. The return loss will be displayed from 0 dB to the value entered in this field.

CAUTION

Damage may result if the power input to the Test Set’s ANT IN port exceeds 60 mW (which is equivalent to 18 dBm). Damage may also result to the unit-under-test if it is overdriven by the D U PLEX O UT power level. To avoid damage to the ANT IN port, enter an over-estimate gain value for t he Max expected gain in dB parameter . To avoid damage to the unit under test, ensure a low power level for the DUPLEX OUT level in dBm parameter.

Estimating Antenna Return Loss

If you are measuring the return los s of an antenna c onnected to the end of a known good feed line, you can determine the approximate return loss of the antenna by subtracting twice the line loss. For example, if you measure a return loss of 24 dB and the line is known to have 2 dB loss, the estimated return loss of the antenna is 20 dB (since there is a total of 4 dB of loss from the feed line). For this estimate to be correct, the coaxial line and connect ors must have a much s maller l oss t han t he total return loss.

Specifications

• Frequency Range: 0.4-1000 MHz, 1.7-2.0 GHz

• Swept Signal Level: -54 dBm to +10 dBm

• Swept Return Loss Accuracy: +/- 2dB +/--10% of reading, for readings between 0 dB and 30 dB

Cable Fault

Measuremen t Description

A frequency-swept signal is tra nsmitted from the DUPLEX OUT port of the Test Set through a resistive power divider to the cable-under-test. The signals reflected from fault s in the cable ar e combined in t he power divider with th e transmitted signal and received at the ANT IN port.

The changing interference of the transmi tted and reflected sig nals, over the swept frequency band, conta ins information about the distance to one or more faults. The software uses a Fast Fourier Transform (FFT) to convert the frequency domain into the t ime domain. The informat ion in the time domain can be used to find the physical distances. The distance displayed on the Test Set’s CRT is the physical distance to the fault with correction for the velocity factor of the cabl e. This test allows the operator to identify, characterize, and isolate potential problem locations by viewing it in units of distance.

NOTE

Test Signal Can Cause Interference When testing cables attached to antennas, test signals will b e radiat ed.

Verify that the signal used for the test cannot result in interference to another antenna.

and select it. Enter the appropriate value. Cables that use polyethylene dielectric typically have a propagation velocity of

0.66, cables that use a teflon dielectric typically have a propagation velocity of 0.70. The propagation velocity must be a value between 0 and 1.

b. Position the cursor at Cable atten. dB/100 ft. (or

meters) at 500 MHz and select it.

c. If the cable attenuation is unknown, enter 0 dB p er 100 feet (or

meters). Entering 0 dB/100 will produce return loss values lower than actual, but fault distance can be accurately detected.

Typical cable fault return loss measurements

Return loss is a ratio of input power to reflected power. For example, if 100 W a tts was applied t o a cabl e and 10 Watts was ret urned, the retur n loss is 10 dB (10 log(100/10)). In the same example, if 1 Watt was returned, the return loss is 20 dB (10 log(100/1)). Typical return loss measurements for the cable loss test are listed below:

• Open-Circuit Cable = 0 dB (ignoring line loss)

• Short-Circuit Cable = 0 dB (ignoring line loss)

• 50-Ohm Terminated Cable = 40 to 60 dB

• Antenna = 10 to 20 dB (in the frequency band for which it was designed)

Return loss measurements greater than 20 dB should be considered good.

Cable Fault Performance

Measurements of the cable fault location can typically be made up to 500 feet on low-loss cables and 300 feet on higher-loss cables. Resolution of the fault location is approximately 0.4 feet for cable lengths up to 50 feet and then linearly increases to 4 feet for a 500 foot cable.

Specifications

• Cable Types Tested: Helia x, RG, Cust o m

• Cable Length Range: 0 to 1000 feet, 0 to 300 meters

• Distance accuracy: +/-5% of the cable length value entered by the user

Replot Data Files

This utility allows you to easily retrieve and display plots which were previously stored on an SRAM PC card. One or two plots may be displayed at one time. No measurements are performed.
