*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.

ALL commands on this page are sent as a string argument from: CONTrol:CALPod:COMMand <string>
Use single quotes ONLY (NOT double quotes) for the CONT:CALP:COMM string arguments.
Sending queries requires TWO question marks. See following note as example.
To read errors with the commands on this page, use the Calpod query:
CONT:CALP:COMM? 'SYSTem:ERRor?'
ALL queries return strings.

CALPod:AVERage < num >

Applicable Models: All (Read-Write) Sets the number of OSL averages used during initialization and recorrect. See important notes.
Parameters
<num>	Number of OSL averages to apply. Use an integer between 1 and 100.
Examples	CONT:CALP:COMM 'CALP:AVER 8'
Query Syntax	CONT:CALP:COMM? 'CALP:AVER?'
Return Type	Numeric
Default	4

CALPod:DISable <port>

Applicable Models: All (Write-only) Unassign Calpod serial number from the specified VNA port. See important notes.
Parameters
<port>	VNA port number to un-assign.
Examples	CONT:CALP:COMM 'CALP:DIS 2'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-read) Assign or return the Calpod serial number for the specified VNA port. If a Calpod module is already assigned to the specified VNA port, this assignment will replace the existing assignment. See important notes.
Parameters
<port>	VNA port number to be assigned the Calpod serial number.
<sn>	Calpod serial number.
Examples	CONT:CALP:COMM 'CALP:ENAB 2, 0001234' 'WRITE CONT:CALP:COMM? 'CALP:ENAB? 2' 'READ
Query Syntax	CONTrol:CALPod:COMMand? 'CALPod:ENABle? <port>'
Return Type	String
Default	Not Applicable

Applicable Models: All (Write-only) Hides the Calpod setup dialog. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:HIDE'

Default	Not Applicable

Applicable Models: All (Write-only) Performs the initialize process for the active (selected) channel. Select a channel using CALCulate:MEASure:PARameter. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:INIT:ACT'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-only) Performs the initialize ALL channels process. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:INIT:ALL'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-only) Starts the Calpod software. The Calpod software can be started using this (Launch) command or by activating the Calpod user interface. Once the Calpod software is started it remains active until the VNA application is terminated. Send this command first in your program, then wait a couple seconds while the software starts before sending the next command. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:LAUN' wait 3
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Read-Write) Enables or disables the ‘Correct Power’ setting in the Calpod setup dialog. See important notes.
Parameters	0 – disable power correction 1 – enable power correction Note that ON and OFF cannot be used as arguments to this command.
Examples	CONT:CALP:COMM 'CALP:POW 1'
Query Syntax	CONT:CALP:COMM? 'CALP:POW?'
Return Type	Numeric
Default	0 (disabled)

Applicable Models: All (Write-only) Performs the recorrect process for the active (selected) channel. Select a channel using CALCulate:MEASure:PARameter. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:REC:ACT'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-only) Performs the recorrect process for ALL channels. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:REC:ALL'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-only) Shows the Calpod setup dialog. See important notes.
Parameters	None
Examples	CONT:CALP:COMM 'CALP:SHOW'
Query Syntax	Not Applicable
Default	Not Applicable

Applicable Models: All (Write-only) Sets the specified Calpod module to specified impedance state. See important notes.
Parameters

<state>	Impedance state. Not case sensitive. Choose from: Short, Open, Load, or Thru
Examples	CONT:CALP:COMM 'CALPod:STATe 0001234,thru'
Query Syntax	Not Applicable
Default	Thru

Applicable Models: All (Read-only) Returns the temperature of the specified Calpod module in degrees Celsius. See important notes.
