Model 8901B Operation
Description HPL
Initial Setup
BASIC
The test setup is the same for all of the checks. Connect the Modulation Analyzer to the bus
controller via the HP-IB interface.
Do
not connect any equipment
to
any of the Modulation Analyzer's
input connectors.

.......................
H P 98034A (use "revised" version with 9835A and 9845A)
The HP 9825A uses HPL. The HP 9835A and HP 9845A use BASIC. You can also use H P Series 200
Controllers which use BASIC, (Code differences exist between the BASIC used by the H P 9835A and
HP 9845A and the BASIC used by the HP Series 200 Controllers. These code differences are specified
in the procedure.)
Procedures
Using the table of instructions under each function, read the description of the purpose of the
commands and then enter the commands appropriate to your controller exactly as described. Check
that the instrument responds correctly.
Address Recognition Check.
This check determines whether or not the Modulation Analyzer
recognizes when it is being addressed and when it is not. This check assumes only that the Modulation
Analyzer can properly handshake on the bus. Before beginning this check, set the Modulation
Analyzer's POWER switch to STBY, then to ON.
Set the Remote Enable
(REN) bus
control line false.
Send the Modulation Analyzer's listen
address.
Check that the Modulation Ana-
lyzer's
LISTEN
annunciator is on.
Unaddress the Modulation Ana-
lyzer
by
sending a different address

OUTPUT 71 5
Check that the Modulation Analyzer's
LISTEN
annunciator is turned off.
Remote/Local Messages and the v L 1 Key Check.
This check determines whether the
Modulation Anal zer ro erly switches from local to remote control, from remote to local control,
and whether the
r & f
key returns the instrument
to
local control. This check assumes that the
Modulation Analyzer is able to both handshake and recognize its own address. Before beginning this
check, select 40.0 SPCL.
