1. (Std Name)
Offset Z0
Sets the impedance Z0 between the measurement plane and the
standard being defined. Normally, this value is set to the
characteristic impedance of the system.
:SENS{1-16}:CORR:COLL:CKIT:STAN1:Z0
Offset Loss
Sets the offset loss for the standard. The offset loss is an energy
loss due to skin effect on the length of single coaxial cable. Input
the energy loss at 1 GHz using the unit W/sec. In most applications,
setting the offset loss to “0” should not affect the result. The offset
loss of a standard can be determined by measuring the offset delay
and the loss at 1 GHz and then substituting them in the following
formula:
:SENS{1-16}:CORR:COLL:CKIT:STAN1:LOSS
Arb.
Impedance
Sets the value for the LOAD standard. Use this option to input an
arbitrary impedance that is different from the system impedance.
:SENS{1-16}:CORR:COLL:CKIT:STAN1:ARB
Min.
Frequency
Sets the minimum frequency for the standard.
:SENS{1-16}:CORR:COLL:CKIT:STAN1:FMIN
Max.
Frequency
Sets the maximum frequency for the standard.
:SENS{1-16}:CORR:COLL:CKIT:STAN1:FMAX
Media
Sets the media type of the standard.
:SENS{1-16}:CORR:COLL:CKIT:STAN1:CHAR
Return
Returns to the softkey display screen one level higher.
2. (Std Name) Displays softkeys for changing the definition of 2. (Std Name). The lower-level softkeys displayed are the same as
those for
1. (Std Name).

21. (Std Name) Displays softkeys for changing the definition of 21. (Std Name). The lower-level softkeys displayed are the same as
those for
1. (Std Name).
Return Returns to the softkey display screen one level higher.
Specify CLSs Displays softkeys for setting the classes of standard. A standard class refers to a set of standards that are used in
the process of calibration. For each class of OPEN, SHORT, LOAD, and THRU, designate standards to be used
from among the 21 standards.
Sub Class Displays softkeys for setting multiple calibration kits.
Sub Class 1 Selects sub class 1.
