Applicable Models: All Important Notes:
(Read-Write) Specifies the default manner in which calibrations that are performed using SCPI or COM are to be stored. Cal data is ALWAYS stored to the channel Cal Register regardless of this setting. This setting survives instrument preset and reboot. It remains until changed by another execution of this command. Note: Cal Set arguments used with commands such as SENS:CORR:COLL:GUID:INIT, SENS:CORR:COLL:GUID:SAVE and SENS:CORR:COLL:GUID:SAVE:CSET will override of any of these default preference settings. Learn about Cal Registers and User Cal Sets. |
|
|
Parameters |
|
|
<char> |
CALRegister - Each Cal is saved ONLY to the channel Cal Register. If the error terms from a new Cal can co-exist with those in the Cal Register, they are appended. USER - Each Cal is saved to its own new User Cal Set file. The Cal Set name is automatically generated. To change the name, send SENS:CORR:CSET:NAME after the cal is complete. This reverts to pre-6.0 behavior. REUSe - The cal is saved to the Cal Set that is currently selected on the specified channel, which could be the channel Cal Register. If the channel does not yet have a selected Cal Set, the cal will be saved to a new User Cal Set with an automatically-generated name. If the error terms from a new Cal can co-exist with those in the Cal Set, they are appended. |

Applicable Models: N522xB, N523xB, N524xB, M9485A This command is replaced with SENS:CORR:PREF:CSET:SAVE NOTE: With 6.0 we implemented a change that defaults to saving completed calibrations to Cal Registers instead of User Cal Sets. To revert to the old behavior, send this command as ON (1). For UI and COM use, this can be done from the GPIB console. (Read-Write) Specifies whether cal data is automatically saved to a User Cal Set file after performing a SCPI calibration. Cal data is always saved to a Cal Register regardless of this setting. This setting survives instrument preset and reboot. It remains until changed by another execution of this command. Learn about Cal Registers and User Cal Sets. |
|
|
Parameters |
|
|
<bool> |
ON or 1 - Cal is automatically saved to a User Cal Set file when performing a SCPI calibration. The Cal Set name is automatically generated. To change the name, send SENS:CORR:CSET:NAME after the cal is complete. Reverts to pre-6.0 behavior. OFF or 0 - Cal is NOT automatically saved to a User Cal Set. To save a calibration to a User Cal Set, use SENS:CORR:COLL:GUID:INIT. |

Applicable Models: All (Read-Write) Specifies whether or not the VNA should perform orientation of the ECal module during calibration. Orientation is a technique by which the VNA automatically determines which ports of the module are connected to which ports of the VNA. Orientation begins to fail at very low power levels or if there is much attenuation in the path between the VNA and the ECal module. If orientation is turned OFF, the SENS:CORR:PREF:ECAL:PMAP command must be used to specify the port connections before performing a cal. Note: For 3-port or 4-port measurements, when orientation is OFF, you are not allowed to specify how the ECAL module is connected. Instead, the VNA determines the orientation. Use SENS:CORR:COLL:GUID:DESC? to query the orientation. The VNA does not verify that you made the connection properly. This setting remains until the VNA is restarted or this command is sent again. |
|
|
Parameters |
|
|
<bool> |
ECAL orientation state. Choose from: ON or 1 - VNA performs orientation of the ECal module. OFF or 0 - VNA does NOT performs orientation of the ECal module. |

Applicable Models: All (Read-Write) When ECal module orientation is turned OFF (SENS:CORR:PREF:ECAL:ORI), this command specifies the port mapping (which ports of the module are connected to which ports of the VNA) prior to performing ECal calibrations. This setting remains until the VNA is restarted or this command is sent again. |
|
|
Parameters |
|
|
<module> |
Specifies which ECal module this port map is being applied to. Choose from: ECAL1 .through. ECAL50 |
|
<string> |
Format this parameter in the following manner: Aw,Bx,Cy,Dz where
Ports of the module which are not used are omitted from the string. For example, on a 4-port ECal module with port A connected to VNA port 2 port B connected to VNA port 3 port C not connected port D connected to VNA port 1 the string would be: A2,B3,D1 If either the receive port or source port (or load port for 2-port cal) of the CALC:PAR:SELected measurement is not in this string and orientation is OFF, an attempt to perform an ECal calibration will fail. |

This command is no longer supported. Learn more about old and new behaviors. (Read-Write) Sets and returns a preference for the Unguided Cal behavior described below. This setting persists until it is changed. This preference can also be set ON by executing the script on the VNA at C:/Program Files/Keysight/Network Analyzer/System/wincal32.reg. |
|
|
Parameters |
|
|
<bool> |
Boolean - Choose from: 0 - OFF - Reverts to new (preferred) behavior. An error is returned if standard data is not acquired before sending SENS:CORR:COLL:SAVE. 1 - ON - (WinCal compatible) Prevents SENS:CORR:COLL:SAVE from failing when standard data has not, and will not, be acquired. |

Applicable Models: All (Read-Write) Sets and returns the preference for the trigger behavior during a calibration. This setting persists until it is changed. Note: If TRIGger:SOURce = Manual, during a calibration the VNA ALWAYS switches to Internal for one trigger, then back to Manual, regardless of this preference command. |
|
|
Parameters |
|
|
<char> |
Character - Calibration type. Choose from: GUIDed - preference setting pertains to a Guided calibration. UNGuided - preference setting pertains to an Unguided calibration. |
|
<bool> |
Boolean - Choose from: 0 - OFF - The trigger behavior during the specified calibration type DOES respect the setting of the TRIGger:SOURce command. For example,when Trigger source = External, the single trigger method will wait for the External trigger signal and then allow only one sweep. 1 - ON - (Pre-6.0 behavior) The trigger behavior during the specified calibration type does NOT respect the setting of the TRIGger:SOURce command. For example, when Trigger source = External, during calibration the VNA switches to Internal sweep, responds to one trigger signal to measure the standard, then switches back to External. |

|
Parameters |
|
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1. |
|
<boolean> |
ON (1) - TWO identical sets of standards will be used to simultaneously calibrate two ports (for both Forward and Reverse parameters). OFF (0)- ONE set of standards will be used to perform a full 2-port calibration, one port at a time. When specifying ON (use two sets), the SENS:CORR:COLL:ACQuire command uses the same standard index for each calibration class. To specify the calibration standard gender for each port, you must first ensure that the order of calibration class accurately reflects the configuration of your DUT. For example, for a DUT with a male connector on port 1 and a female connector on port 2, order the devices within the S11 classes (A, B, and C) such that the MALE standards are first in the list. Then order the S22 classes specifying the FEMALE standards as the first in the list. |
