data file must exist on the software disk before the program will
proceed with testing. If such a file does not exist, the program will
prompt the user to enter calibration data through the computer
keyboard. The sensor calibration data is then stored on the software
disk. An existing power sensor calibration data file may be reviewed
or modified by re-entering the power sensor serial number in the LIST
OF DEFAULTS display.
After the LIST OF DEFAULTS display, the next display allows the user
to select whether the test results will be printed out or displayed on
the spectrum analyzer CRT.
Next, the program checks to verify that each piece of test equipment
responds at its designated HP-IB address. The user is prompted with a
list of test equipment that does and does not respond, and is offered
the choice of continuing with the program, repeating the equipment
check, or returning to the LIST OF DEFAULTS display to change HP-IB
addresses. The program will automatically limit the number of tests
that can be performed, based on this list of available test equipment.
If the user chooses to proceed by pressing a), the program attempts
to measure the spectrum analyzer CAL OUTPUT signal, and prompts
the user to connect the CAL OUTPUT to the RF INPUT and adjust the
front-panel AMPTD CAL and FREQ ZERO controls as appropriate.
Refer to Figure 5-3 for the location of the AMPTD CAL and FREQ
ZERO controls. Once these adjustments are within tolerance, the
program activates the spectrum analyzer error correction (KSW)
routine.
Once the error correction routine has completed, a test summary is
displayed on both the computer and the spectrum analyzer. Both test
summaries provide a status report on test progress. In addition, the
test summary displayed on the spectrum analyzer provides the user
with a selection menu of individual tests. The user enters the number
of the desired test, followed by IHz) to perform the test one time, or
[kHz) to perform the test repetitively. If the user selects “All Tests”
(selection 0), the program will run each of the tests in sequence,
skipping those tests that cannot be performed with the available test
equipment.
Test results are printed or displayed at the completion of each
individual test. Once a particular test is completed, the test summary
displays are updated to reflect whether the test passed.
