RF Measurements
The measured values differ from the displayed trace in two ways. First, any filtering applied to the channels
is not displayed on the trace. Second, the single value of measured noise for a channel is subtracted from
each trace point in the channel, rather than offsetting the entire channel by a single amount. This produces
a smooth trace with no discontinuities at the channel edges.

Description
Sets the number of Main channels.
Sets the bandwidth of the Main channels.
Sets the frequency difference between the centers of the Main channels.
Selected channels are ignored by the measurement routine.
Opens the Edit Channel Parameters dialog, which you use to specify the parameters of a
new pair of adjacent channels. You can add up to 50 adjacent channel pairs.
Opens the Edit Channel Parameters dialog box. (You must first select a channel to
enable the Edit button.)
Deletes the selected main channel or adjacent channel pair.
Add a new pair of adjacent channels at the bottom. Their parameters are copied from
the channels just above them.
A table of the parameters for every channel. Offset is the frequency difference between
the Center Frequency and center of the selected channel. Nothing in the table is editable
directly.
