5.7. GPIB / USB / RS-232 / Ethernet Interface Command List
Echo and Response Considerations
USB/RS-232 Responses
The USB/RS-232 bus will automatically send any response back to the controller's
input buffer.
GPIB Queries and Responses
The GPIB bus will not send any data to the controller without being queried. A
GPIB read command must be sent after a command string to retrieve any data
from a query command (?).
5.7.1. Rules for Sending Commands to the Instrument
The following conventions are used to describe the commands syntax for the
SC6540:
Braces ({ }) enclose each parameter for a command string.
Triangle brackets (< >) indicate that you must substitute a value for the
enclosed parameter.
The Pipe ( | ) is used to separate different parameter options for a
command.
The command and the parameter data must be separated with a space.
Each command string should be terminated by the ASCII control code, New
Line (NL), (OAh) or the end of line (EOL) message for GPIB.
All commands that end with a question mark (?) are query commands and
required an IEEE-488 read command to retrieve the data from the device's
output buffer.
5.7.2. Scanner Channel Configuration Commands
The following commands are used to create or modify Test Setup Files.
