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
118000 136000 Suppression of range 118 to 136 kHz
98550 98450 Suppression of range 98.450 to 98.550 kHz
0 0 Empty frequency pair (irrelevant)
118375 0 Suppression of frequency 118.375 kHz
0 123400 Suppression of frequency 123.400 kHz
127675 127675 Suppression of frequency 127.675 kHz
In the status reporting system the states of the traces are coded in status bits (see "Status Reporting
System" on page 5.128).
TRACe? SSTART|SSTOP
This query causes the data to be taken from the already corrected table.
1st frequency 2nd frequency
118000 136000
98450 98550
0 0
118375 118375
123400 123400
127675 127675
Clearing the suppress lists must always include both commands (TRAC SSTART, 0; TRAC SSTOP, 0).
