SYSTem:ERRor?
Reads and clears one error from the error queue.
Parameter
(none)
Reads and clears the first error in error queue: SYST:ERR?
The front-panel ERR annunciator turns on when one or more errors are currently stored in the
l
error queue. Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them.
When you have read all errors from the error queue, the ERR annunciator turns off.
If more have accumulated than the queue can hold, the last error stored in the queue (the most
l
recent error) is replaced with -350,"Error queue overflow". No additional errors are stored until you
remove errors from the queue. If no errors have occurred when you read the error queue, the
instrument responds with +0,"No error".
The error queue is cleared by the *CLS and when power is cycled. It is not cleared by a *RST.
l
Errors have the following format (the error string may contain up to 80 characters).
l
<error code>,<error string> For a list of error codes and message strings, see
Messages.
SYSTem:GROup:CATalog?
This command does NOT apply to models
Returns the groups that have been defined. The defined groups are enclosed in quotes.
Parameter
(none)
returns the channels that are grouped: SYST:GRO:CAT?
Example response with 4 channels; no channels grouped: "1","2","3","4"
l
Example response with channels 1 and 2 grouped; 3 and 4 grouped: "1,2","3,4"
l
Example response channels 1 - 3 grouped; channel 4 not grouped: "1,2,3","4"
l
SYSTem:GROup:DEFine (@<chanlist>)
This command does NOT apply to models
Groups multiple channels to create a single channel. This effectively creates a single output with
higher current and power capability. You can group up to four channels per mainframe.
