HP 8901B

Model 8901B Operation
Abort Message Check. This check determines whether or not the Modulation Analyzer becomes
unaddressed when
it receives the Abort message. This check assumes that the Modulation Analyzer
is able to handshake, recognize
its own address, make the remote/local changes, and enter serial-poll
mode. Before
beginning this check, select 40.0 SPCL.
Description
Send the Remote message
to the Modulation Analyzer.
Check that the Modulation An-
alyzer’s REMOTE and LIS-
TEN annunciators are on.
Send the Abort message, unad-
dressing the Modulation Analyzer.
Check that the Modulation Analyzer’s
LISTEN annunciator is
off. Note that
the HP 9835A and 9845A ABORT10
statement sends both the Abort message
and the Local message. Thus, if the HP
9825A is being used, the Modulation
Analyzer’s REMOTE annunciator should
remain on.
If the HP 9835A or 9845A is
being used, the Modulation Analyzer’s
REMOTE annunciator should turn
off.
I Send the Local message (HP 9825A)
only.
Address the Modulation An-
alyzer to talk and then store
its output data
in variable V.
Check that the Modulation Ana-
lyzer’s LISTEN annunciator is
off
but that its TALK annunciator is on.
Send the Abort message unaddress-
ing the Modulation Analyzer to talk.
