Address.
The Modulation Analyzer’s HP-IB address
is
set
to
decimal 14
at
the factory
with Talk Only and Listen Only modes disabled. The address can be changed by following the
instructions in paragraph 2-3 under “HP-IB Address Selection”.
Reading
the
Address.
To display the HP-IB address in decimal on the front panel, select BUS ADRS
by pressing the Blue key and then the LOCAL key. The displayed address
is
in
the form:
Where
NN
is the two-digit address in decimal. The display will time out
after
a few seconds.
Refer to “Additional Information”, paragraph 3-1

MODULATION ANALYZER REMOTE CAPABILITIES (IEEE-488)
The capabilities of the HP 8901B
in
remote operation and their related
IEEE
Std
488 terms are
described in Table
3-7,
“Modulation Analyzer Remote Capabilities Table”. The twelve capabilities
described there are further described
in
the paragraphs following the table.

Modulation Analyzer Capabilities
Response
All
front-panel functions, special functions, and remote-only
functions are programmable, except the
POWER
switch. The
Modulation Analyzer can send the Status Byte, and message and
setting information.
All
measurement results, special displays,
and error outputs (except dashed displays) are available via the
bus.
If
in
remote and addressed to listen, the Modulation Ana-
lyzer makes a settled measurement. It responds equally to
bus
command
GET
and program code
T3,
Trigger
with
Settling.
Clears Status Byte,
RQS
bit,
Service Request message
(if
issued), and sets the
SRQ
Mask to the
22.0SP
state. Responds
equally to
DCL
and
SDC
bus
commands. Resets many additional
parameters as shown
in
Table
3-8,
“Response to a Clear
Message.”
