Setting Port Extensions and Loss Values

Setting loss values

In addition to port extension, you can set loss values for each port. By correcting loss due
to port extension, more accurate measurement results are obtained.
There are two types of loss value settings: loss values at two frequency points for a
specified port, and a DC loss value. You can make these settings at the same time for each
port.
NOTE You can set loss values channel by channel. Setting loss values for one particular channel
does not affect other channels.

Step 8. If you want to set loss values for other ports, repeat Step 5 to Step 7.
NOTE When you specify two frequency points, set the lower frequency to Loss1, and the higher
one to Loss2.
