SINGLE�puts the active trace into the single display format. If both traces are active, trace A is
displayed.
SOURCE�displays the source menu, which is used to set the source amplitude and select
the type of source signal. The measurement modes offer these source outputs:
The source is band·limited at spans
BURST CHIRP�outputs a frequency chirp for the specified portion of the time
BURST RANDOM .. ·outputs a true random noise burst for the specified portion of the
DC OFFSET �used to add positive or negative dc offsets to the source output. The
FIXED SIN E�provides a constant·frequency sine wave. The frequency is entered
MANUAL SWEEP�selects manual sweep and activates the Entry group to move the
