Hp 8340B/41B Hp-Lb Operation Verification Test - HP 8340B Manual

4-17. HP 8340B/41B HP-lB OPERATION VERIFICATION TEST

This HP-lB test is an automated test; a Desktop Computer is required.
Two software listings are supplied. Table 4-32 gives a BASIC program
listing for the HP 85F; Table 4-33 gives a BASIC program listing for the HP
9826A (HP 226) or 9835A (HP 236). The test procedure applies to either
test program used.
Description
The test program given in Table 4-32 is written to verify the HP 8340B/41B HP-lB interface by writing
to and reading from the instrument. The program also displays the DUT's status bytes similar to the
format shown in Table 4-31, HP 8340B/41B Status Byte Descriptions. Upon running the program the
status bits displayed will change initially as the program outputs an IP
sweep), and
two TS
(program lines 120 to 300 for the HP 8SF, program lines 130 to 350 for the HP 9826A/9836A), the
status bits should all be zeros and the DUT should be in LOCAL mode. The procedure instructs the
operatorto press specific HP 8340B/41 B front panel keys and perform certain functions which should
set specific bits of the status bytes. This procedure will test most of the bits in the two status bytes.
However, if the instrument is working properly, the status bit for the Fault Indicator On, the Oven Cold,
and the Self Test
Failed will
program will test the data bits by outputting a series of binary numbers to the DUT and reading back
each it outputs. If a bit is held HIGH or LOW, the number read will not agree with the
number that
number written and the program will display an error message. This procedure does not test all of the
HP-lB control lines.
