The Start Cal submenu selects the calibrated ports and the calibration type.
The calibration types depend on the number of test ports of the analyzer. For a four-port unit:
One-Port P1 and One Port P2 open submenus to select a one-port calibration at test ports PORT 1 and PORT 2, respectively.
Two-Port P1 P2 opens a submenu to select a two-port calibration at test ports PORT 1 and PORT 2.
Three-Port P1 P2 P3 opens a submenu to initiate a three-port (TOSM) calibration at test ports PORT 1, PORT 2 and PORT 3.
Four-Port P1 .. P4 opens a submenu to initiate a four-port (TOSM) calibration at test ports PORT 1, PORT 2, PORT 3 and PORT 4.
Other... opens the calibration wizard to select a calibration type for an arbitrary number of ports.
Use Other... if you wish to perform several calibrations in a single measurement sequence and with a minimum of effort. The Other... calibration wizard allows you to measure a particular standard and reuse the results for different calibration types.
One-port to 4-port calibrations can be performed automatically using the Calibration Unit (accessory R&S ZV-Z51/-Z52...). For calibrations with more than 4 ports use the calibration units R&S ZV-Z58/-Z59.

Opens a submenu to select a one-port calibration at test ports PORT 1 or PORT 2. The two submenus are identical:
One-port calibrations can be performed automatically or manually.
Calibration Unit starts an automatic full one-port calibration. This function is enabled while the Calibration Unit is connected.
The following menu commands calls up the start dialog of the calibration wizard to start a manual calibration:
Normalization (Short) initiates a normalization using a short standard.
Full initiates a full one-port calibration.
[SENSe<Ch>:]CORRection:COLLect:AUTO ' ', <port_no> (for matching analyzer and cal unit ports) [SENSe<Ch>:]CORRection:COLLect:AUTO:PORTs (for arbitrary pairs of ports)

Opens a submenu to select a two-port calibration at test ports PORT 1 and PORT 2:
Two-port calibrations can be performed automatically or manually.
Calibration Unit starts an automatic tow-port TOSM calibration. This function is enabled while the Calibration Unit is connected.
Normalization Both Directions... initiates a normalization using a through standard.
One Path Two Port initiates a full one-port calibration.
TOSM initiates a Through-Open-Short-Match (12-term) calibration
TOM initiates a Through-Open-Match calibration
TRL initiates a Through-Reflect-Line calibration
TNA initiates a Through-Network-Attenuation calibration
Normalize Forward and Normalize Backward initiate a normalization in forward and backward direction, respectively. The normalization uses a through standard, however, only one direction is normalized.
Use Start Cal – Other... to select a UTOM calibration.

Opens a submenu to select a three-port TOSM calibration at test ports PORT 1, PORT 2 and PORT 3:
Three-port calibrations can be performed automatically or manually.
Calibration Unit starts an automatic 3-port TOSM calibration. This function is enabled while the Calibration Unit is connected.
Manual... calls up the start dialog of the calibration wizard to initiate a 3-port TOSM calibration.
Use Start Cal – Other... to select other 3-port calibration types.

Opens a submenu to select a four-port TOSM calibration at test ports PORT 1 to PORT 4:
Four-port calibrations can be performed automatically or manually.
Calibration Unit starts an automatic 4-port TOSM calibration. This function is enabled while the Calibration Unit is connected.
Manual... calls up the start dialog of the calibration wizard to initiate a 4-port TOSM calibration.
Use Start Cal – Other... to select other 4-port calibration types.
