 Offset parameters must be assigned to both physical ports of a logical port.
 Auto Length corrects the length offset of both physical ports of a logical port by the same
amount.
The offset parameters can be defined separately for each port.
 Reset Offsets sets all length offsets to zero.
 Electrical Length defines electrical length offsets and loss parameters at all test ports.
 Mechanical Length defines mechanical length offsets and loss parameters at all test ports.
 Delay defines delay times and loss parameters at all test ports.
 Auto Length determines a length offset for the receiving port of the active measured quantity with
the condition that the residual group delay of the active trace is minimized.
 Auto Length and Loss determines a length offset an loss for the receiving port of the active
measured quantity with the condition that the residual group delay of the active trace is minimized
and the measured loss is minimized as far as possible across the entire sweep range.
 Fixture Compensation, corrects the measurement result for the effects of a text fixture.
The Zero Delay at Marker function overwrites the Offset parameters.

Electrical Length
Opens a dialog to define the length offset parameters for the physical test ports as electrical lengths. The
dialog also contains the DC loss, the loss at the reference frequency Loss(f
ref
), and the reference
frequency f
ref
; see Loss parameters: Definition above.
Compensate Meas's Transm. indicates the ports for which a direct fixture compensation has been carried
out, replacing the offset parameters.
Since the loss at the reference frequency is stored as loss per length, it can only be changed if the
corresponding length is larger than zero.
