The HP 8568A/B Operation Verification program requires an HP 9000
Series 200 or HP 9000 Series 300 computer with HP BASIC 2.0
and Extensions 2.1 or BASIC 3.0 or higher. An HP 362 or HP 382
computer can also be used and requires BASIC 6.2 or higher. The
program operates on either a single or dual HP-IB computer system.
For a dual bus system it is also necessary to have an HP 98624A HP-IB
Interface to connect the HP 8568AB to the computer separately from
the test equipment.
The Operation Verification software is designed for optimum operation
with a dual bus system. The dual bus system is used with the
Microwave Test Set (MTS). In this configuration, the bus for the test
equipment has a select code of 7, while the bus for the instrument
under test has a select code of 8. The software will adapt itself to a
single bus system if an HP 98624A HP-IB Interface at select code 8 is
not present.
The equipment needed to perform the HP 8568A/B Operation
Verification is listed in both Table 5-l and 'lhble 5-3. 'Iable 5-l includes
a test-by-test listing of the equipment needed,
a test equipment summary. To obtain a permanent record of the test
results an HP-IB printer is required. The HP 8568A/B CRT display
may be selected to display the test results if a permanent test record
is not desired.
Because test results are expected to change over a period of time,
Hewlett-Packard warrants only the specification range and not the
repeatability of the data for any given specification.
For a dual bus system, connect the test equipment to the computer
as shown in Figure 5- 1. The instrument under test is connected
separately to the HP 98624A Interface card.
For a single bus system, connect the test equipment and instrument
under test to the computer (as shown in Figure 5-2).
Turn the HP 8568A/B m to On and allow a 2 hour warm-up.
Also, allow sufficient warm-up time for the other test equipment as
indicated in the individual operating and service manuals.
When connecting signals from the synthesized sweeper or tracking
generator to the test setup, it is necessary to use a high frequency
cable with minimum attenuation to 1.5 GHz.
