HP 8340B/41B
HP-IB OPERATION VERIFICATION
TEST
(Cont'd)
Procedure
1.
Connect the equipment as shown
in
Figure 4-22. Enter the program shown in Table 4-32
if the HP
85F is
used, or the program in Table 4-33
if the HP 9826A
or
9836A
is
used.
Press the RUN
key.
The
program
will display the DUT's status bytes similar to Table 4-31. After the program goes
through the output loop routine about two times, all
status
bits should
be
"0"
and the
DUT
should
be
in
LOCAL mode
(front panel
REMOTE
indicator not ON).
2.
Press the DUT's [INSTR PRESET]
key. After going through the output loop about
three times,
status byte
1 decimal value should be 24 (bits 4
and
3 set).
NOTE
After pressing an
HP 8340B/41B
front panel key, watch the displayed
decimal value. When the decimal value changes, press the controller
PAUSE key.
Note the
status bits that are
set
and press CONT.
3.
Press the
DUT's [CW]
key. After the program goes through the output
loop about three times
all
status
bits should be "O"; however, status byte
1,
bit
1,
should have been set during one of the
output loop passes. Enter
[1] [5] [GHz]
and the byte 1
status
bits will change, but after about
2
passes
all
status
bits should be "O".
5.
Switch the DUT's rear panel
FREQUENCY REFERENCE
switch to EXT. Status
byte 2
value
should be
24 (bits 4
and
3 set).
Return the switch
to INT.
6.
Press the controller softkey
K1
(SYNTAX).
NOTE
There
will be about
a
6
second delay before the status
bits
change.
The program will output the character
string "XYZ"
to the
DUT. The DUT
should not recognize
this string
and should set status byte
1,
bit 5
(SRQ on HP-IB Syntax
Error).
7.
Press the controller softkey K4 (DATA BIT).
The program will test
all
data
bits and display an
error
message
If
any
bits fail the test, or
if all bits
pass the test, the program will
display "ALL DATA
BITS
WORKING."
