  ================================================================
 
 
The HP-IB addresses for the equipment used in the Operation 
Verification program are as follows:

          HP 3335A               Decimal Address   04
          HP 436A, Option 022    Decimal Address   13
          HP 8568B               Decimal Address   18



If you wish to use addresses other than those listed above, the
instrument address assignments must be changed in the main program. 
The addresses are located near the top of the program and are clearly
identified. The Operation Verification manual contains futher important
information concerning the verification program. Some of the items covered in
the manual are:

 * What the Operation Verification program actually verifies.

 * What to do if you have trouble running the program.

 * What to do if the test instrument is out-of-tolerence.
 
USING THE PROGRAM
 
Getting Started

After presentation of preliminary instructions and information,
the program advances to a pre-calibration routine. This routine is 
important because the validity of the tests depends, in 
part, on proper instrument calibration. Please follow all instructions as
they appear on the spectrum analyzer CRT. 

Testing

Single Tests.  Any of the tests may be performed singly by entering the 
test number on the spectrum analyzer data keyboard and pushing Hz.
The test is then performed before the program returns to the test menu.

Repeat test.  Any test may be performed repetitively by entering the test
number followed by kHz. The program continues to perform the specified test
until the MHz key is pushed. This aborts the current test and returns the
program to the test menu.

All Tests.  All fifteen tests may be performed in sequence by entering
0 Hz on the data keyboard. The fifteen tests are performed in the 
order listed. Whenever an equipment change is required, the new 
test setup is displayed on the spectrum analyzer CRT and the program
is halted until the new connections are completed.

Test Results

The test number, title, specification, and measured data are printed
on an HP-IB printer or on the spectrum analyzer CRT, depending on your 
selection. If no printout is selected, only the test menu is updated.
If the measured data indicates that a parameter is out-of-tolerence, a double
astrisk (**) is placed adjacent to the data. The printout also lists the title
of the Performance Test (in the Tests and Adjustments manual) related to the 
parameter that is out-of-tolerence. Verfication of an instrument failure re-
quires that this test be performed.

Other Instructions

All necessary instructions for proper operation of this program are displayed
on the spectrum analyzer CRT as they are needed. Follow all instructions as 
they appear and remember that the current test can be aborted by pushing MHz
and waiting for the program to return to the menu.
