Command Timing; Sequential/Overlapped Commands - ILX Lightwave LDC-3926339 User Manual

Numeric data is required with *PSC (1 = on, 0 = off), *RCL (0 to 10, see Save and
Recall on page 15), *SAV (1 to 10, see Save and Recall on page 15), *ESE (0 to
255, see page 40), *SRE (0 to 255, see page 62), and *PUD (used at factory
only).
The *CAL? query returns "1" if all LDC-3926 modules' self-calibration routines are
completed properly, otherwise "0" is returned.
The *TST? query returns "1" if all LDC-3926 modules that were working at power-
up (or at the time of the last *TST? query) have responded to the LDC-3926339
within the past 15 seconds. If any modules fail to respond to the mainframe,
*TST? returns "0", and those modules are no longer recognized by the system.
A list of all of the IEEE 488.2 Common Commands supported by the LDC-
3926339 follows.
*CAL?
*ESE?
*OPC
*PSC?
*RCL
*SRE?
*TST?

Command Timing

This section describes, for each command, whether the command is performed in
an overlapped or sequential manner. Command timing states whether the next
command can begin while another command is being executed, or if the next
command must wait until this command is completed before its execution begins.
See Operation Complete Definition on page 34 for information about the operation
complete flag.

Sequential/Overlapped Commands

All common commands for the LDC-3926339 module are sequential and most
device-dependent commands are executed before the previous command is
complete.
All device-dependent commands are executed in an overlapped manner (except
the DELAY command); subsequent commands begin before the current
command is completed. The common commands are sequential; the next
command must wait until the previous command is completed. The operation
complete flag (OPC) is set after the conditions outlined in the Operation Complete
Definition are satisfied.
