============================================
 
  The HP-IB addresses for the equipment are:
 
   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 the
ones listed, the instrument address assign-
ments 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 more
important information concerning the veri-
fication program. Some of the items covered
in the manual are:

* What the Operation Verfication 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 instruc-
tions, the program advances to a pre-cali-
bration routine. This routine is im-
portant because the validity of the
tests depend, in part, on proper instru-
ment calibration. Please follow all instruc-
tions as they appear on the spectrum 
analyzer CRT.

Testing

Single Tests

Any of the tests may be performed singly
by entering the test number followed by the
spectrun analyzer data keyboard and push-
ing Hz. The test is then performed before 
the program returns to the test menu.

Repeat Tests

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

All Tests

All fifteen tests may be performed in
sequence by entering 0 Hz on the data key-
board. The fifteen tests are performed in
the order listed. Whenever an equipment
change is necessary, a new test setup is
displayed on the spectrum analyzer CRT 
and the  program is halted until new con-
nections 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 para-
meter is out-of-tolerence, a double astrisk
(**) is placed adjacent to that data. The
printout also lists the title of the Per-
formance Test (in the Tests and Adjustments
Manual) related to the parameter that is
out-of-tolerance. Verification of an
instrument failure requires that this
Performance 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.
