CONTrol:CALPod:COMMand <string>

(Write-Read)  Sends commands that control a Calpod module. Reads query versions Calpod commands.

See ALL Calpod commands.

Learn more about Calpod.

Parameters

 

<string>

Calpod command. See ALL Calpod commands that can be used in this string.

Write Example

CONT:CALP:COMM 'CALP:INIT:ACT'

'Enclose all strings in SINGLE quotes (NOT double quotes)

Query Syntax

CONTrol:CALPod:COMMand? <string>

Relevant only for query strings.

Read Example

CONT:CALP:COMM? '*OPC?'

'returns 0 if the calpod software is currently processing an operation

'returns 1 if operations are complete

Return Type

String

Default

Not Applicable

CONTrol:ECAL:MODule<num>:PATH:COUNt? <name>

(Read-only)  Returns the number of unique states that exist for the specified path name on the selected ECal module.

This command performs exactly the same function as SENS:CORR:CKIT:ECAL:PATH:COUNt?

Use the CONT:ECAL:MOD:PATH:STAT command to set the module into one of those states.  

Use SENS:CORR:CKIT:ECAL:PATH:DATA? to read the data for a state.

Parameters

 

[num]

Optional argument. USB number of the ECal module.  If unspecified (only one ECal module is connected to the USB), <num> is set to 1. If two or more modules are connected, use SENS:CORR:CKIT:ECAL:LIST? to determine how many, and SENS:CORR:CKIT:ECAL:INF? to verify their identities.

<name>

Name of the path for which to read number of states.  Choose from:

Reflection paths

  • A

  • B

  • C (4-port modules)

  • D (4-port modules)

Transmission paths

  • AB

  • AC (4-port modules)

  • AD (4-port modules)

  • BC (4-port modules)

  • BD (4-port modules)

  • CD (4-port modules)

Note: For each transmission path, the first of the available states is the through state, the second is the confidence (attenuator) state.

Examples

CONT:ECAL:MOD:PATH:COUNt? A

control:ecal:module2:path:count? cd

See example program

Return Type

Integer

Default

Not Applicable

CONTrol:ECAL:MODule<num>:PATH:STATe <path>, <stateNum>

(Write-only) Sets the internal state of the selected ECAL module. This command supersedes CONT:ECAL:MOD:STAT.

Parameters

 

[num]

Optional argument. USB number of the ECal module.  If unspecified (only one ECal module is connected to the USB), <num> is set to 1. If two or more modules are connected, use SENS:CORR:CKIT:ECAL:LIST? to determine how many, and SENS:CORR:CKIT:ECAL:INF? to verify their identities.

<path>

Path name for which to set a state.  

Note: The impedance paths are not independent. For example, changing the impedance presented on path A will cause a change to the impedance on path B.

Choose from:

Reflection paths

  • A

  • B

  • C (4-port modules)

  • D (4-port modules)

Transmission paths

  • AB

  • AC (4-port modules)

  • AD (4-port modules)

  • BC (4-port modules)

  • BD (4-port modules)

  • CD (4-port modules)

<stateNum>

Number of the state to set. Refer to the following table to associate the <stateNum> with a state in your ECal module.

In addition, CONT:ECAL:MOD:PATH:COUNt? returns the number of states in the specified ECal module.

CONTrol:ECAL:MODule<num>:STATe <value> Superseded

This command is replaced with  CONT:ECAL:MOD:PATH:STATe.

(Write-only) Sets the internal state of the selected ECAL module.

Parameters

 

[num]

Optional argument. USB number of the ECal module.  If unspecified (only one ECal module is connected to the USB), <num> is set to 1.  If two or more modules are connected, use SENS:CORR:COLL:CKIT:INF? to verify their identity.

<value>
