System Events
System events have positive valued codes. They are not defined by SCPI, but are specific to the instrument. Sending
the :STATus:PRESet command will disable these events from being reported.
401 Power on
402 Operation complete
The *OPC command has been executed.
Warnings
The execution of some commands might cause an undesirable instrument state. The commands are executed, but a
warning is issued. Sending the :STATus:PRESet command disables reporting of warnings. The existence of these
conditions causes a bit in the Status Questionable Condition register to be set (refer to section 4.13.5.4).
For Model 4075
500 Trigger rate short
510 Output overload
For Model 4078
500 Trigger rate short on channel 1
501 Trigger rate short on channel 2
510 Output overload on channel 1
511 Output overload on channel 2
"Trigger rate short" means that the period of the waveform is larger than the value of the internal trigger rate. Thus
not every trigger will generate a cycle (or burst) of the waveform.
4.12 Common Commands
The following section describes the common commands according to the IEEE 488.2 specifications. These
commands are applicable for both GPIB and RS-232 interface.
4.12.1 System Data Commands
a) *IDN? - Identification query
The identification query enables unique identification of the device over the GPIB. This query should
always be the last in a program message. It returns a string with four fields:
Manufacturer name
Model name
Serial number (0 if not relevant)
Version number
Command
Type:
Common Query
Syntax: *IDN?
