*IDN?
IIviDriverIdentity (IVI-compliant)
*IDN?
For the Serial BERT, the Identification Query (*IDN?) response semantics are
organized into four fields, separated by commas. The field definitions are as follows:
Table 11
Field Value
Manufacturer Agilent Technologies
Model N490xx
Serial Number DExxxxxxxx
Firmware Level A.x.x.xxx
*OPC
IAgilentN490xSystem.WaitForOperationComplete (not IVI-compliant)
*OPC
The *OPC command sets the Operation Complete (OPC) bit of the Standard Event
Status Register (ESR) when the No Operation Pending flag is TRUE ( No Operation
Pending flag is attached to each overlapped command). Until that time, the
controller may continue to parse and execute previous commands. It is good
technique, then, to periodically poll the OPC bit to determine if the overlapped
command has completed.
N O T E
For the Serial BERT, *OPC can be used with overlapped commands. For more
information, see “Overlapped and Sequential Commands ” on page 80 the .
