number of seconds. Terminate this command with a].
Entering a 0 in wait x causes the instrument to wait for prior
sequence command activities to finish before allowing the
next command to begin. The wait 0 command only affects
the command immediately following it, and does not affect
commands later in the sequence.

bandwidth search feature analyzes a bandpass or band reject
trace and calculates the center point, bandwidth, and Q (quality
factor) for the specified bandwidth. Bandwidth units are the
units of the current format.

Four markers are turned on, and each has a dedicated use.
Marker 1 is a starting point from which the search is begun.
Marker 2 goes to the bandwidth center point. Marker 3 goes to
the bandwidth cutoff point on the left, and Marker 4 to the
cutoff point on the right.
If a delta marker or fixed marker is on, it is used as the
reference point from which the bandwidth amplitude is
measured. For example, if marker 1 is the delta marker and is
set at the passband maximum, and the width value is set to
-3 dl3, the bandwidth search 0nds the bandwidth cutoff points
3 dB below the maximum and calculates the 3 dB bandwidth
and Q.
If marker 2 (the dedicated bandwidth center point marker) is
the delta reference marker, the search finds the points 3 dB
down from the center.
If no delta reference marker is set, the bandwidth values are
absolute values.
