Set
Query
Description Sets and queries the frequency span of the sweep. 900 Hz
is the default frequency span. The span frequency is equal to
the stop-start frequencies.
Note To sweep up or down, set the span as positive or negative.
The maximum span frequency has a relationship to the center
frequency and maximum frequency:
max freq span= 2(max freq
– center freq)
