Notes:
These commands provide for the following:
Measure the ECal module with adapters, cables, or fixtures to be included in the User Characterization.
Allow descriptive text to be entered.
Save the User Characterization to the ECal module or PNA disk memory. Up to 12 User Characterizations can be stored in an ECal module. Learn more.
You can NOT perform a remote User Characterization of a 4-port ECal module using a 2-port PNA. This can only be done from the front panel user interface.
Example - Perform an ECal User Characterization
|
(Write-only) Initiates the measurement of the ECal module. The user characterization process must have been initiated first using SENS:CORR:CKIT:ECAL:CHAR:INIT. Currently, only ONE step is required to measure the ECal module. Note: This command is an overlapped command. When *OPC is issued with it, the OPC bit in the PNAs Standard Event Status Register is not set until this command has completed its operation. Learn more. |

Parameters |
|
|
<ch> |
Channel number being calibrated. If unspecified, value is set to 1. Channel number being calibrated. |
|
<step> |
Integer User characterization step number to be measured. |

(Read-Write) Sets and reads the number to which the User Characterization will be stored in the ECal module. The number must be set before sending SENS:CORR:CKIT:ECAL:CHAR:INIT or the default value (1) will be used. This command is NOT necessary when saving the User Characterization to the PNA disk memory. |
|

(Read-only) Returns a list of connector names that are valid for use with user-characterized ECal modules. Use an item from the returned list to specify a connector for SENS:CORR:CKIT:ECAL:CHAR:CONN:PORT. Use only factory-defined connector types when you store a user characterization to PNA disk memory. |

(Read-Write) Specifies a connector type name for every ECal module port used during the user characterization. Valid connector names are returned using SENS:CORR:CKIT:ECAL:CHAR:CONN:CAT? This command refers to the ECal ports by number instead of letter (1 = Port A, 2 = Port B, and so forth). The connector names should be set for the ports before sending SENS:CORR:CKIT:ECAL:CHAR:INIT. The following steps could be followed to ensure port connectors are specified correctly:
Note: Use only factory-defined connector types when you store a user characterization to PNA disk memory. |

|
Parameters |
|
|
<ch> |
Channel number being calibrated. If unspecified, value is set to 1 |

|
<string> |

(Write-only) Initiates an ECal User Characterization. The specified channel number must be an S-parameter measurement channel. The channel must already be calibrated using the same, or greater number of PNA ports as the ECal module. Also, the calibrated PNA ports must begin with Port 1 and use sequential port numbers. After this command is executed, subsequent commands can be used to query the number of measurement steps, issue the acquisition commands, query the connection description strings, and subsequently complete an Ecal User characterization. |

|
|
<ch> |
Channel number of a calibrated S-parameter channel. If unspecified, value is set to 1 |
