The following commands are sent as a string argument from:
CONTrol:CALPod:COMMand <string>
CALPod INITialize | ACTive | ALL RECorrect | ACTive | ALL |
Click on a blue keyword to view the command details.
In addition to the above Calpod commands, the following IEE 488 Common Commands can also be sent as a string argument:
*CLS - Clears all errors and event data from the error/event queue.
*IDN? - Returns the instrument identification information.
For 4 state CALPod support the following is required.
CCT (configurable command table) version 1.4
Controller FPGA version 8.4
*OPC? - Operation complete query. This query immediately returns a value, independent of whether or not the operation is complete. A return value of 0 indicates the operation is not complete. A value of +1 indicates the operation is complete. Typically this command is used in a loop with a 0.25 second delay when waiting for an operation to complete.
*TST? - Performs a communication test on all the currently enabled Calpods. 0 = Test failed on one or more enabled Calpods. 1 = All enabled Calpods working.
SYSTem:ERRor? - Queries the Event/Error queue and returns the most recent error element.
