7.5 Calibration
7-44
{DON’T CARE}
: It is used when error correction is not performed with the
connector.
{DEFINE STANDARD}
: Calls the user specification menu.
When using an user selected calibration kit, its
parameters should be entered. (Refer to sub-section
7.5.8.)
FEMAL/MAL selection menu
{PORT 1 FEMAL/MAL}
: Sets FEMAL/MAL of the port 1 connector.
{PORT 2 FEMAL/MAL}
: Sets FEMAL/MAL of the port 2 connector.
{PORT3 FEMAL/MAL}
: Sets the PORT3 connector to FEMAL or MAL.
* This is available when OPT11 (Built-in 3-port test set)
or OPT14 (Built-in 4-port test set) is installed.
{PORT4 FEMAL/MAL}
: Sets the PORT4 connector to FEMAL or MAL.
* This is available when OPT11 (Built-in 3-port test set)
or OPT14 (Built-in 4-port test set) is installed.
CAUTION!
The setting of the cal kit is effective in 1 port and 2 port full calibration.
As the correction data is calculated by using this set parameter when {DONE} is pressed
at each calibration, if the setting of cal kit is changed after the {DONE} pressed, it has no
effect on the calibration.

Parameters Entry of an User-selected Calibration Kit
This function sets the parameters of an user-selected calibration kit.
(1)
Open standard
The electric length between the calibration part and the opening part, and the open capaci-
tance can be entered.
The open capacitance is determined with C

(f: frequency)
The open capacitance is a frequency function and can be extended as the equation shown
above.
(2)
Short standard
The electric length between the calibration part and the short part can be entered.
(3)
Through standard
Electric length, loss and impedance can be entered. Loss should be entered the resistance
per unit length of the through standard.
The units of the parameters are expressed as follows:
Electric length
