Running Tests

Loading the Software

Before you begin testing, you must load the software into the test set memory. To load the software, you must first select the location to load from (in this case, it will be Card) and a procedure filename. The HP 11807A,E Option 100 card comes pre-programmed with five procedures, and four different libraries. Each library is associated with its own software program. The actual software program does not get loaded into the test set memory until take approximately two minutes for the software program to be loaded at that time.

The software memory card can be removed after the program is loaded into the test set memory. The program will remain in memory after a power-down/power-up cycle, unless it is manually deleted or a new program is loaded (for example, if you select a procedure in a different library).

Customizing Testing

Because of the diversity of individual testing needs, the software has

been designed so that changes may be easily made from the test set’s front panel. You may store these changes on a memory card so that you may skip these steps in the future. See “Saving a Test Procedure” on

page 28.

Because your needs change, the software allows changes to its default settings whenever you need to make them. For example, tests may be inserted or deleted, and later after running the tests you can change the test parameters.

Most testing customization is accomplished through the customization screens. These customization screens are accessed from the main TESTS (Main Menu) screen as shown in the following figure. Customizing procedures is explained later in this chapter.

Changing the Order of Tests

You can define the order of tests to include all, some, or just one of the tests available. Each library has a different set of available tests. You cannot combine tests from different libraries into one procedure. When the first test is finished, the next will run. The test sequence will

remain in the test set’s battery backed-up memory until another test sequence is loaded or set up. For information on saving a customized test sequence, see “Saving a Test Procedure” on page 28.

NOTE

Libraries are not selected directly. When you select a procedure filename, the associated library is automatically selected as well. The Library field on the TESTS (Main Menu) screen displays the current library. Note that each library has a separate set of tests and parameters. You may not combine tests from separate libraries into one procedure.

Defining the order of tests is accomplished by inserting or deleting tests from the list of tests in the active library. See “Test Descriptions” in

Chapter 4 through chapter 6 describe the tests included in each

library in this software package.

The following procedure describes how to create a new test sequence. The All Chans field is not used by this software package.

Changing the Test Parameters

The software uses parameters to optimize the test environment and conditions for your testing situation. Many of the test parameters are determined by examining your test needs. Each library has a unique set of parameters. Each procedure comes with default settings for test parameters. Review the defaults for your particular needs.

NOTE

The HP 11807A,E Option 100 software comes preprogrammed with four libraries: RFTOOLS, FIELD_S, INTRMOD, and SCANNER. The test, parameter, and channel information tables are different for each of these libraries. Each library accesses a separate software program, also contained on the software card. Each library will be described in its own chapter (chapters 3 through 6 )

For information on saving customized test parameters, see “Saving a

Test Procedure” on page 28.

The following describes how you can change test parameter values through the Test Parameter screen to optimize your testing conditions.

Saving a Test Procedure

A Test Procedure is a collection of test parameters and testing order (and channel information for FIELD_S and SCANNER libraries), saved in a file that customizes the test software to a specific application. You may save the file to a memory card or disk.

When you save a procedure you will be saving test parameters and testing order (and channel information in FIELD_S and SCANNER programs), plus a library containing the names of all test parameters and tests that are resident in the current library. The HP 11807A,E Option 100 software contains four libraries: RFTOOLS, FIELD_S, INTRMOD, and SCANNER. Each library file comes from the software and cannot be modified by the user. The current library file will be automatically saved on the card that is being used to store the new test procedure.

The following example shows how to save a new procedure to a memory card. For more information concerning procedures, see “Procedures” on

page 125.

Swept Gain Test

This test measures the gain of a device by sweeping it over the specified frequency range. You will be prompted to enter the frequency range over which the device is to be swept.

This test requires two 6-dB pads. The pads are put on the antenna and duplex ports on the test set to improve the mismatch of the ports. A reference level is obtained by connecting a short calibration cable between the pads on the duplex and antenna ports. Next, the test device is added between the calibration cable and one of the pads, and a measurement is made of the additional gain from the reference level. The trace of the device gain over the frequency range swept is displayed. The maximum gain is also displayed on the screen.

Swept Return Loss Test

NOTE

The Test Signal Can Cause Interference (Setting Duplex Out Power Level)

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 interference to other nearby antennas. When running the program, set the duplex out power level to a minimum value for good measurement resolution. Set the frequency range carefully.

If you are a cellular operator in an area with other receive antennas nearby, you may want to use the AMPS Channel Return Loss test. This test measures the return loss at a frequency offset from a selectable range of AMPS channels. The offset (in kHz) from the AMPS channels can be set.

This test measures the return loss of a cable or device in the swept mode. A SWR bridge and a 6-dB pad are connected to the test set. The pad is used to improve the mismatch between the SWR bridge and the ANT IN port on the test set. You will be prompted at the start of the test to enter the start and stop frequencies. A reference level is measured with a short or open and the return loss is measured with the cable or antenna-under-test. The trace showing return loss over the frequency band selected is displayed on the screen. Measured values for best and worst case return loss are printed at the top of the screen. VSWR can be calculated from the return loss. The following Table 3-1 contains some of the values from a calculation.

VSWR is sometimes stated as a ratio. For example: 1.2:1 or “one point two to one” VSWR. The first number is given in the tables and formula. The second number is always one.

Estimating Antenna Return Loss

If you are measuring the return loss of an antenna connected 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. This estimate is in error if the coaxial line and connectors do not have a return loss somewhat greater than 24 dB.

NOTE

Running the Swept Return Loss Test

1. From the RFTOOLS Test Menu, select Swept Return Loss.

2. Enter your desired values for the start frequency, stop frequency, duplex out level in dBm, and the maximum expected loss in dB.

The default values in this list can be changed by editing Parameters 1, 2, 8, and 9 in the Edit Parameter screen. See “RF Tools: Parameter

AMPS Channel Return Loss Test

This test measures the return loss in a device for discrete cellular AMPS channel frequencies. This test is performed at channels entered by the user and offset by a frequency to make the measurement between actual channels. A reference level is measured on the spectrum analyzer with a short or open on the SWR bridge DUT port. The return loss is then measured with the cable or antenna-under-test on the SWR bridge DUT port.

This test should be used when there is a chance that a full frequency sweep of the band to be tested may cause interference. In this test, the chance of interference is greatly reduced by selecting an offset that sets a CW test frequency between the assigned AMPS channels. For example, selecting an offset of 15 kHz places the test signal between adjacent AMPS channels and adjacent NAMPS channels.

See “Swept Return Loss Test” on page 42 description for a return loss

to VSWR conversion table and formula and a way to estimate the return loss of an antenna connected to the end of a feed line.

1. From the RFTOOLS Test Menu, select AMPS Channel Return Loss.

2. Enter your desired values for the start channel, stop channel, step channel, offset frequency in MHz, band RX or TX, and duplex out level in dBm.

To avoid overdrive damage to your device under test, ensure that you are setting an appropriately low duplex out power level.

Cable Fault Test

RFTOOLS Library: Procedure, Test, and Parameter Descriptions

Test Descriptions

NOTE

The Test Signal Can Cause Interference

When testing cables attached to antennas, test signals will be radiated. Verify that the signal used for the test cannot result in interference to

another antenna. The software reduces the signal generator’s level except when it is needed to actually perform the measurement.

This test operates over a wide frequency band. The test will always operate with a center frequency of 505 MHz. The frequency span however will be determined by the length of the cable measured. Longer cables will use a narrower frequency span. The frequency span will equal 990 MHz for cables less than 50 feet long and equal approximately 99 MHz for cables 500 feet long. It is always safe to assume that the frequency span is less than or equal to 990 MHz.

This test displays the return loss of a transmission line as a function of the distance down the line. A frequency-swept signal from the DUPLEX OUT port is applied through a resistive power divider to the cable-under-test. Signals reflected from faults in the cable are combined with the DUPLEX OUT signal in the power divider and applied to the ANT IN port. The changing interference of the forward and reflected signals, over the swept frequency band, contains information about the distance to one or more faults. The software uses a Fast Fourier Transform (FFT) to convert the frequency domain into the distance domain. The distance displayed on the test set’s CRT is the physical distance to the fault with correction for the velocity factor of the cable.

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.

Velocity Factors And Attenuation

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. If the cable attenuation is unknown, enter 0 dB per 100 feet (or meters). Entering 0 dB/100 will produce return loss values lower than actual, but fault distance can be accurately detected.

RFTOOLS Library: Procedure, Test, and Parameter Descriptions

Test Descriptions

NOTE

Typical Cable Fault Return Loss Measurements

Return loss is a ratio of input power to reflected power. For example, if 100 Watts was applied to a cable and 10 Watts was returned, the return loss is 10 dB (10 log (100/10)). In the same example, if 1 Watt was returned, the return loss would be 20 dB (10 log (100/1)). Typical return loss measurements for the cable loss test are listed below:

• Open-Circuit Cable = 0 dB

• Short-Circuit Cable = 0 dB

• 50-Ohm Terminated Cable = 20 to 30 dB

• Antenna = 10 to 20 dB

Return loss measurements below 25 dB should be considered excellent. For best results, the cable output should be terminated in 50 ohms.

Entering Cable Length

The greatest accuracy is obtained when you enter a cable length slightly greater than the actual cable length, considering length uncertainty. If you are not sure of the cable length, enter a value 1.5 times the estimated length. Depending on the return loss of the antenna or device at the end of the cable, you may see a high relative mismatch displayed at the actual length of the cable.

NOTE

Parm_18 Cable fault: [0=RG 1=HELIAX 2=Custom] selects the cable

class. Parm_19 Cable type: [1>13 for Heliax, # for RG] sets the type of cable to be measured. If the cable is ‘RG’, enter the RG type in parm_19 (for example: for type RG 58/U, enter 0=RG in parm_18, and ”58” in

parm_19). If the cable is Heliax, enter the number corresponding to the list below in parm_19. If the cable is Custom, use parameters 20 and 21 to enter the cable attenuation and propagation velocity.

Interpreting Cable Fault Location Results

Distance to the cable fault is accurately quantified when you select the USER Disp data field. The return loss levels and distance at which the faults occur are displayed. Numeric data for the six smallest return loss values of data from the graph are listed. Values greater than 25 dB can be ignored. The smallest return loss is most likely the location of a cable fault. Other numeric data points, particularly if they are further down the line from a point of high relative mismatch, can be ignored. Data points on the fringe of a point of high relative mismatch are usually attributable to the single fault.

SA Self Calibration ON/OFF

This test allows you to check the status of the test set’s spectrum analyzer, and change the status if you desire.

The RFTOOLS program uses the test set’s internal spectrum analyzer for making network analyzer measurements. The internal spectrum analyzer performs an automatic self calibration every 5 minutes. This automatic self calibration insures that the spectrum analyzer operates within specified limits regardless of the operating temperature. However, this self calibration can introduce instability in spectrum analyzer output after the test set is operating at a constant temperature (after approximately 30 minutes).

Each RFTOOLS test includes two parts; calibration and measurement. If the spectrum analyzer performs a self calibration between the calibration and measurement of the RFTOOLS test, the spectrum analyzer automatic self calibration instability will increase RFTOOLS test measurement error. To avoid this problem, you may use this test to turn off the spectrum analyzer self calibration. This self calibration should only be turned off after the unit has reached a constant powered-on operating temperature (approximately 30 minutes after power-on). By turning the self calibration off, the measurement accuracy and stability of RFTOOLS tests will improve.

Create/Edit Data Collection Labels

This test will only appear on the RFTOOLS Test Menu, if Parm_22 Use

data collection labels [0=No 1=Yes] is set to 1=Yes. If this parameter is

set to 1=Yes , before performing the measurement the software will prompt: Would you like to label the data from this test?. If you press choices:

• Return to testing without labeling data (in case you pressed Yes by

mistake).

• Enter label manually, and select label from a list.

This test allows you to create and edit files containing up to 50 labels to be stored on an SRAM card. These labels can be used later for labeling test output, in conjunction with the data collection function. Data collection allows you to store all the test data in a file which is named at the beginning of the test procedure. Data collection labels allow you to label each individual measurement. Data collection label files are stored under the filename uLAB_#, where # can be any value between 1 and 999.

k1 (Yes), the software will prompt you with the following

When test results are stored to a data collection file, (sent to a PC or printer) it may be convenient to separate the data by labeling each measurement. For example, you may want to test the insertion loss of several test cables without repeating the calibration step in between measurements. The first five tests on the RFTOOLS Test Menu permit repetitive testing after initial calibrations are performed.

There are two ways to create data collection labels: using this test to create and store the labels, or waiting until you have a measurement that you would like to label and creating it then. For either method, you must set parm_22 Use data collection labels [0=No 1=Yes] to 1=Yes. If you would like to use the same label(s) several times, it would be useful to run this test to create the labels and store them in a file which can be retrieved when desired. If it is not likely that you will use the same label several times, but you would still like to label the test output, you may do so when prompted.

Labels can be entered using the characters in the Choices menu, or by using a terminal emulator program. See “Collection to a PC” on page

100 for information on setting up a terminal emulation program.

Intermodulation Products Theory of Operation

Intermodulation products are calculated beginning with the first three transmit frequencies (f

2nd order product frequencies = f 3rd order product frequencies (2 TX Freqs)= f 3rd order product frequencies(3 TX Freqs)= f 5th order product frequencies = 2f

is checked against f4, f5…f20

This process continues on through the remaining transmit frequencies. As the INTRMOD program is calculating, the program can check all intermodulation products to see if they exactly match the specified receive frequency or the upper and lower adjacent channels. If a match is found, it is displayed as 2nd, 3rd, or 5th order products.

Setting Up Intermodulation Products Parameters

1. Press TESTS.

2. Select Card in the Select Procedure Location: (or Location:)

field.

3. Select the test procedure INTRMOD.

4. Set parm_1 to the exact frequency, in MHz, that you are concerned intermodulation frequencies are affecting. (Most likely it will be a receive (RX) frequency.)

5. Select ParmTest Parameters from the Customize Test Procedure list (or Edit Parm from the Test Function field).

6. Set parm_2 through parm_21 to the transmitter frequencies in MHz that could be causing intermodulation products. (If you are setting less than 20 transmit frequencies, always start with parm_2, any test parameters left empty should always be set to “0”.)

7. Set parm_ 22 to the channel spacing, in MHz, which is the adjacent channel spacing for your receiver system.

• TEST_01 SCANNER

S:\HP11807A\OPT100\MANUAL\scanner.fm

SCANNER Library: Procedure, Test, and Parameter Descriptions

Procedures Pre-programmed in the SCANNER Library

The SCANNER library comes pre-programmed with two procedures:

•SCAN_DIS

•SCAN_SWP

SCAN_SWP runs a swept scan using values the user entered for start frequency, stop frequency and step frequency. SCAN_DIS runs a discrete scan of preprogrammed channels. To run these tests properly, the user should customize the Channel Information (Edit Freq) and Parameter table (Edit Parm) to enter the information specific to the test site. Remember to save the customized values to a new test procedure before changing the entry to the Select Procedure Filename: field. When the Select Procedure Filename: field is selected, the channel information and parameter values reset to the original default values if the new procedure was not saved. See Chapter

2 , “Loading and Running the Software,” on page 13 for information on

how to save a test procedure.

Setting Up Discrete Scan Frequency Information

1. Press the TESTS key.

2. Select Card in the Select Procedure Location: (or Location)

field.

3. Select the test procedure SCAN_DIS.

4. Select FreqChannel Information from the CUSTOMIZE TEST PROCEDURE list (or Edit Freq from the Test Function field).

5. Select the inverse-video box in the Chan# column. Turn the knob until the desired frequency (or position in the column) you want is highlighted in an inverse-video box, then push the knob to clear the cursor from the Chan# field.

Procedures Pre-programmed in the SCANNER Library

6. Select the inverse-video field in the Col A Freq (left column) or Col B Freq (right column), depending upon which frequency you want to

change. Key in the desired frequency in MHz.

Up to 100 frequencies can be entered into the program for scanning. Col A Freq is for frequencies 1A through 50A, and Col B Freq is for frequencies 1B through 50B.

The program uses the TestA? (or Test?) and TestB? (or Prime?) fields to determine if the frequencies listed in the right and left frequency columns are scanned. TestA? (or Test?) corresponds to the frequency in Col A Freq (left column), and TestB? (or Prime?) corresponds to the frequency in Col B Freq (right column). Selecting Yes in TestA? or TestB? causes the respective frequency in the same row to be scanned, and selecting No causes the respective frequency in the same row to be skipped.

The program scans frequencies sequentially from left to right, top to bottom. Frequencies set to 0.000 MHz are skipped. When a Col A

Freq or Col B Freq is set to −1, the software stops scanning at that

point and starts over at the beginning of the scan sequence.

7. Select the inverse-video field below the frequency you set in the

previous step and enter a “label” to identify the frequency to be scanned.

The label field can also be used to select AM or FM demodulation. For example, If the label begins with “AM:”, the AM demodulator will be used. If no label is entered, or if the label does not begin with AM: or FM:, the default demodulation will be FM except in the aircraft band and AM broadcast band.

Labels are optional, they are displayed with the received frequency when a channel is monitored by the frequency-scanning program.

7 Save/Recall Register Utility

(SAVRCL)

The SAVRCL procedure allows you to save instrument settings in save/recall registers for future use. This allows you to retrieve entire instrument setups instead of having to re-enter the individual settings.

Save/Recall Register Utility (SAVRCL)

This utility is used to manipulate those save/recall registers.

Common uses of this utility include copying save/recall registers from one test set to another and backing up registers before a firmware upgrade on a test set (firmware upgrades erase all registers from the

test set’s memory).

This program provides the following operations:

• Catalog a memory card to see what files are on it (page 87).

• Purge files from the card (page 88).

• Copy the save/recall registers in the test set to a memory card (page

89).

• Copy save/recall registers from a memory card to a test set (page

91).

• Format a memory card (page 92).

CAUTION

Save/Recall registers save all test set settings that have been changed from the factory power-on defaults. This includes any settings that are used to access optional hardware features, such as a cellular adapter or optional audio filters.

If all of your test sets are equipped with the same hardware options and the same firmware revision, you can usually copy registers from one test set to another without problems.

However, if the hardware options and firmware revisions do not match, copying registers may cause the instrument to attempt to access hardware settings that are not available and will freeze test set operation (also called a “firmware assert”). In this case, its power must be cycled to clear the problem.

This procedure does not use any parameters, specifications, or other customizable settings.

Save/Recall Register Utility (SAVRCL)

Saving Registers to a Memory Card

Saving save/recall registers to a formatted memory card provides a way to copy registers to other test sets. (See page 92 for information on formatting the card.) It also allows you to restore the registers in a test set that has had a firmware upgrade or has had its memory assembly replaced. It may also be helpful when you need to run a program that

uses most of the test set’s RAM memory, requiring you to remove the save/recall registers that occupy memory space in the test set.

Saving a register to a memory card does not remove the original register from the test set it is copied from.

CAUTION

The test lets you save registers with names of up to nine characters in length. However, memory card file names can only be seven characters long. When copying registers with names of more than seven characters to a memory card, the test set shortens the name to seven characters by cutting off the last characters. When saving registers in the test set, you should try to use names of seven characters or less.

Also, any register names that were saved in the test set using lower case letters (through programs) will be copied to the memory card using all upper case letters.

Although the test set lets you save registers using the underscore character (_), do not save registers using the underscore for the first character (such as _cell23). The SAVRCL program creates its own unique file for each saved register using the underscore at the start of the name to identify instrument settings. Creating your own files using the underscore at the start could prevent the register from being successfully copied.

Use the following procedure to save registers to a memory card:

1. Load and run the SAVRCL procedure (see page 18).

2. Insert a formatted SRAM memory card into the test set.

Copying Files

You can copy a file from a memory card to an SRAM memory card by loading the program from the memory card into the test set, inserting an initialized SRAM memory card, and then using the IBASIC SAVE command. Enter the following:

SAVE “MY_TEST:INTERNAL”

You can list the names of the files stored in a memory card catalog by using the IBASIC CAT command. To display a list of file names on a memory card, enter the following:

CAT “:INTERNAL” or CAT

The mass storage powers-up to memory card as a default. If you did not change this setting, then ”:INTERNAL” is optional. If you are entering many characters into the IBASIC command line, you may want to connect a terminal to the test set. See “Serial Connection” on page 119.

You will also want to use a terminal if you have many files to list because file names displayed with the CAT IBASIC command scroll past the top of the test set’s CRT display and cannot be scrolled down.

IBASIC is used when writing your own programs, and is not explained in this manual. See “What is Not Explained in This Manual” on page 21 for a listing of programming manuals.

Data Collection (Saving and Retrieving Test Results)

You will be specifying the file type with the entry you make into the Options field immediately below DATA COLLECTION. If no file type is entered, and the disk format is LIF, the software will select an HP-UX file type. If no file type is entered, and the disk format is DOS, the software will select a DOS file type. For example, if you are using a DOS file and you are not using an extension on the file name, the entry on this screen will look like:

1 DATA COLLECTION 1

If you are using an ASCII, BDAT or HP-UX file, you can specify the number of records allocated to the file. The DOS file is automatically updated as data is stored, so record allocation is not required. If you are using HP-UX files, you will have to enter REC= to establish a usable number of records. REC=20480 sets the size to be the same as the default number of 256 byte records used for ASCII files (80 x 256). You can enter the REC= after the file type. For example, to use an ASCII file with 200 records of 256 bytes each, you will enter ASCII REC=200 into the Options field.

NOTE

For some software revisions, REC= and ASCII REC= will appear in the Choices menu. In this case, you may select REC= or ASCII REC=, enter

the number of records using the DATA keypad, then select Done, instead of typing in each character individually.

The display will appear as follows:

Data Collection (Saving and Retrieving Test Results)

Retrieving Data from a Memory Card

To retrieve the test results after they have been saved on an SRAM memory card, see the “Transfer Stored Data” on page 56.

Collection to a PC

Test results can be output through the serial port. A variety of devices can receive the data. An HP Palmtop computer, PC, laptop, or terminal can be used. A terminal emulator can log the test results to a file. Examples of terminal emulator programs are HP AdvanceLink and ProComm, a product of DataStorm Technologies, Inc.

For example: Configuring an IBM-Compatible PC with HP AdvanceLink for DOS

1. Load and run HP AdvanceLink on your PC.

2. Use the following tables to set the Global Configuration, Terminal Configuration, and Remote Configuration settings.
