Using The Gpib Interface; Available Commands - Avtech AV-1022-C-AS4 Instructions Manual

USING THE GPIB INTERFACE
The AV-1022-C-AS4 incorporates the Avtech OP1 "GPIB bus listener interface".
This section describes how to use the IEEE 488 General Purpose Interface Bus (GPIB)
for remote computer control of the AV-1022-C-AS4.
INTERFACE TO THE GPIB
The Avtech OP1 interface is a simple "listener" interface for the GPIB. It will
receive simple commands from a computer over the GPIB bus, but it does not have the
capability to send any data back to the computer. In more concise terms, the OP1
interface implements the following IEEE 488.1 Capabilities as defined in the IEEE 488.1
Standard:
SHO no "Source Handshake" capability (can not send information)
AH1 complete "Acceptor Handshake" capability (can receive information)
TO no "Talk" capability (can not send information)
TEO no "Talk Extended" capability (can not send information)
L2 basic "Listen" capability (can receive information)
LEO no "Listen Extended" capability (because it is a basic listener only)
SRO no "Service Request" capability (because it is a basic listener only)
RLO "Remote/Local" switching controlled by a back panel switch (not
computer controlled)
PPO no "Parallel Poll" capability (because it is a basic listener only)
DCO no "Device Clear" capability (can not be remotely reset)
DTO no "Device Trigger" capability (can not be triggered by the computer)
CO no "Controller" capability (because it is a basic listener only)
AVAILABLE COMMANDS
The OP1 GPIB user interface is designed to be used to remotely program the
Avtech pulse generator to control the pulse repetition rate, delay, pulse width, and
amplitude.
The available commands, outputs, units and range of acceptable values for the
AV-1022-C-AS4 generator are defined in the table below:
Command Acronym Function Units Range
V set voltage V 0to 5
R set repetition rate Hz 100 to 1000000
WwW set pulse width us 0.05 to 50
D set delay us 0.05 to 50
