*OPC?
IAgilentN490xSystem.WaitForOperationComplete (not IVI-compliant)
*OPC? Command
The *OPC? query returns the ASCII character "1" in the Output Queue when the
No Operation Pending flag is TRUE. At the same time, it also sets the Message
Available (MAV) bit in the Status Byte Register. The *OPC? will not allow further
execution of commands or queries until the No Operation Pending flag is true, or
receipt of a Device Clear (dcas) message, or a power on.
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 .
*RST
IIviDriverUtility.Reset (IVI-compliant)
*RST
The Reset Command (*RST) sets the device-specific functions to a known state
that is independent of the past-use history of the device. The command has the
same effect as the front-panel PRESET key.
In addition, receipt of *RST by the error detector will cause all past results to be
reset to zero.
*SRE[?]
IAgilentN490xStatus.ConfigureServiceRequest (not IVI-compliant)
*SRE <NR1>
*SRE?
The Service Request Enable Command (*SRE) sets the Service Request Enable
Register. This acts as a mask on the Status Byte, defining when the instrument
can issue a service request. For a service request to be issued, the summary bit in
the Status Byte must match the bit in the Service Request Enable Register. More
than one bit may be set by the *SRE command.
