Command List
*IDN?
Returns the instrument identification. The exact response is determined by the instrument
configuration and is of the form <MANUFACTURER>,<model>,0,<serial no XX-xx>>, where XX-xx is the
instrument firmware version number.
*CLS
Clear Status. Clears the Status structure; this indirectly clears the Status Byte register.
*RST
Resets the instrument to the factory default settings − with the exception of all remote interface
settings. These can be viewed in Factory Default Settings.
RCL <N>
<unquoted
string>
Recall a set up for the output <N> specified by <unquoted string> from the internal storage.
File name could be mixture of letters and numbers but up to 8 characters long only.
SAV <N>
<unquoted
string>
Save the instrument set-up for the output <N> to a file < unquoted string> on the internal storage.
File name could be mixture of letters or numbers but up to 8 characters long only.
*SRE<NRF>
Sets the Service Request Enable Register to <NRF>
*SRE?
Return the value of Service Request Enable Register in <NR1> numeric format. The syntax of the
response is <NR1>
*ESE <NRF>

*ESE?
Return the value in the Standard Event Status Enable Register in < NR1>numeric format. The syntax of
the response is <NR1>
*PRE <NRF>

*PRE?
Return the value in the Parallel Poll Enable Register in <NR1>numeric format. The syntax of the
response is <NR1>
*OPC
Sets the Operation Complete bit (bit 0) in the Standard Event Status Register. This will happen
immediately the command is executed because of the sequential nature of all operations.
*OPC?
Query Operation Complete status. The response is always 1 and is available immediately, the command
