Figure 10-25: Offset Embed dock widget: Offset panel

The "Offset" panel can also be activated by selecting the Offset tab or One Way Loss

tab. Refer to its description for additional functions and remote commands.

Active

The checkbox in the "Active" column activates/deactivates the configured length and

loss parameters for the respective Port (i.e. adds/removes them to/from the calculation

flow) without changing the parameter values.

Remote command:

[SENSe<Ch>:]CORRection:OFFSet<PhyPt>:COMPensation[:STATe]

Loss at DC / Loss at 1st Freq / 1st Freq for Loss / Use 2nd Freq / Loss at 2nd

Freq / 2nd Freq for Loss

Defines the one-way loss parameters of the transmission line at the selected port.

In the limit case, where the length of the transmission line is considered to be "almost

zero", the loss is considered constant:

Otherwise, if the loss at DC and one additional frequency f

is known, the loss at fre-

quency f is approximated by:

If, in addition, the loss at a second frequency f

is known and "Use 2nd Freq" is

enabled, then the loss is approximated by:

See also Chapter 9.6.1.2, "Definition of loss parameters", on page 278.

Note: The entered parameters define the loss for a signal traveling in one direction

through the transmission line. To account for the propagation in both directions, the

magnitude shift of a reflection parameter due to a given loss is twice the magnitude

shift of a transmission parameter. See also Chapter 9.6.1.6, "Application and effect of

offset parameters", on page 282.
