Suppress trace:
Remote sees the suppress lists as predefined traces. Each data set contains two traces with the
names SSTART (= Suppress START) and SSTOP (=Suppress STOP).
The suppress list has 100 elements with each element consisting of two frequencies. The
frequency pair specifies a frequency range which is suppressed during the scan. It is irrelevant
that the 1st frequency is lower than the 2nd frequency. The sequence in the list is irrelevant, too.
Gaps are specified by the frequency pair 0.0. If one frequency of the frequency pair is 0, the other
frequency of the pair is seen as a single frequency.
Examples:
1st Frequency 2nd Frequency Description
118000000 136000000 Suppression of range 118 to 136 MHz
98550000 98450000 Suppression of range 98,450 to 98,550 MHz
0 0 Empty frequency pair (irrelevant)
118375000 0 Suppress single frequency 118,375 MHz
0 123400000 Suppress single frequency 123,400 MHz
127675000 127675000 Suppress single frequency 127,675 MHz
In the status reporting system the states of the traces are coded in status bits (see "Status reporting
system" on page 127).

This query causes that the data will be taken from the already corrected table.

Clearing the suppress lists must always include both commands (TRAC SSTART, 0; TRAC SSTOP, 0).
