Command Reference
The following pages contain a reference for the device-dependent commands of
the LDC-3700C Series Laser Diode Controller. This reference contains useful
information for both local and remote operation of the LDC-3700C.
In some references, parentheses are used to signify the labeled area for a
particular switch or LED indicator on the front panel. For example, (TEC
DISPLAY) SET refers to the switch labeled "SET" in the TEC DISPLAY area of the
front panel.
Action Adjusts the internal analog to digital (A/D) converter to reference points, then reports
results.
Results Zero = OK
Non-zero = calibration error
Note A/D referencing is performed each 10 minutes of inactive time.
Example *CAL?
Action Clears status event registers: Event Status, Event Status Enable, and Error Queue.
Note Useful to clear registers before enabling service requests (SRQ).
Example * CLS
Action The DELAY command causes the execution of commands to be delayed by a user-
defined time. This command is similar to the *WAI common command, except that
execution resumes after the specified number of milliseconds, instead of waiting for the
Operation-Complete flag to be set.
Parameters An <nrf value> which represents the delay time, in milliseconds.
Notes: The Operation-Complete flag is held false until the delay period elapses, but the *OPC?
query will not execute until the delay period has elapsed.
This command is useful for creating delays which don't require a lot of program code and
don't tie up the GPIB during execution.
The delay time is approximate, with an error of about 10%.
Care should be taken to set the GPIB time-out appropriately for use with the Delay
command. After this command (or the *WAI) command is sent, the 3700C Series
Controller may receive up to 20 more commands before the delay period is over. If more
