The :SENSe{1-16}:CORRection:COLLect subsystem commands start an actual calibration and are limited to Port1 and/or Port 2. Both 2-port and 4-port VNA instruments can use these commands.
Calibration Setup Subsystems
These subsystems are used during various phases of calibration configuration setup:
These commands are similar to those in the :SENSe{1-16}:CORRection:COLLect[:CALa]:PORT Subsystem above where any port pair on a 2-port or 4-port VNA can be specified.
Related calibration types use the same command structure of:
:SENSe{1-16}:CORRection:COLLect:XXXXX
where the calibration XXXXX type is one of the following:
• 1P2PF = One-path two-port calibration, forward direction
• 1P2PR = One path two port calibration, reverse direction
• FULL1 = Full one port calibration
• FULL2 = Full two port calibration
• FULLB = Full one port reflection calibration, both ports
• RESP1 = One port response calibration
• RESPB = One port response calibration, both ports
• TFRB = Transmission frequency response calibration, both directions
• TFRF = Transmission frequency response calibration, forward direction
• TFRR = Transmission frequency response calibration, reverse direction
Each calibration type command is described in greater detail in the following sections. Related to the calibration commands are calibration simulation commands in the general form of :SENSe{1-16}:CORRection:COEFFicient:XXXXX that use the same abbreviations above.
