Range Start / Range Stop
Sets the start frequency/stop frequency of the selected range.
To change the start/stop frequency of the first or last range, respectively, select the
appropriate span in the SPAN configuration dialog. You can set a span that is smaller
than the overall span of the ranges. In this case, the measurement includes only the
ranges that lie within the defined span and have a minimum span of 20 Hz. The first
and last ranges are adapted to the given span as long as the minimum span of 20 Hz
is not violated.
Define frequency values for each range relative to the center frequency. Center the ref-
erence range on the center frequency. The current "Tx Bandwidth" defines the mini-
mum span of the reference range (see " Channel Power Settings " on page 309).
