Synchronizing the
Digitizer
One method of synchronizing the digitizer with other digitizer’s or with
other instruments is to determine when the digitizer parser is idle. This is
done using the command:
STATus:OPC:INITiate <
state
>
together with the commands:
*OPC
*OPC?
*WAI
The behavior of *OPC, *OPC?, and *WAI depends on the state set by
STATus:OPC:INITiate. When state is ON, sending *OPC, *OPC?, or
*WAI following INITiate:IMMediate,
VINStrument:CONFigure:VME:MEMory:INITiate, or
VINStrument:CONFigure:LBUS:MEMory:INITiate requires the digitizer to
complete all measurements or complete the VME or Local bus data transfer
before allowing further digitizer operations to continue. ON is the power-on
state.
When state is OFF, the execution of *OPC, *OPC?, or *WAI following the
above commands indicates the previous commands have executed and that
further operations (command execution) can resume without the digitizer in
the idle state. Digitizer commands that can be executed during this time are
identified in the command reference (Chapter 4) as being "executable when
initiated". Refer also to the command reference for detailed information on
*OPC, *OPC?, and *WAI.
Saving Digitizer Configurations
To minimize repeated programming, up to 10 digitizer configurations can
be saved and later recalled. The configuration saved is restored, with the
exception of the STATus subsystem parameters, the CALibration:SECure
command state, or any other parameters not affected by *RST.
A configuration is identified by a number from 0 thru 9. The
configuration(s) is saved until power is cycled.
