5.4 The GPIB Capability of the Power Meter
GPIB
Capability
Response Interface Functions
Talker/Listener Commands and response messages can be sent
and received over the GPIB bus. Status
information can be read using a series poll.
AH1, SH1, T6, L4
Service
Request
The Power Meter sets the SRQ line true if there
is an enabled service request condition.
SR1
Remote/Local The Power Meter powers up in local state. In
local state, the front panel is operative, and the
Power Meter responds to the commands from
GPIB. In remote state, the
RMT of indicator
will be lighted up and all front panel keys
except the “<SETUP>” key are disabled.
Press “<SETUP>” key to return the Power
Meter to local state.
RL1
Device Clear The Power Meter responds to the Device Clear
(DCL) and Selected Device Clear (SDC)
interface commands. These cause the Power
Meter to clear any activity that may prevent it
from receiving and executing a new command.
DCL and SDC do not change any programmed
settings.

Introduction to Programming
All commands and response messages are transferred in form of ASCII codes. The response
messages must be read completely before a new command is sent, otherwise the remaining
response messages will be lost, and a query interrupt error will occur.
Conventions
Angle brackets < > Items in angle brackets are parameter abbreviations.
Vertical bar | Vertical bar separates alternative parameters.
Square brackets [ ] Items in square brackets are optional. For example,
FETCh[:SCALar] means that :SCALar may be omitted.
Braces { } Braces indicate the parameters that may be repeated.
The notation <A> {<, B>} means that parameter “A” must
be entered while parameter “B” may be omitted or entered
once or more times.
