:SWEep:PROGgress
[SOURce]:SWEep:PROGgress?
This
query
returns
the
progress
of an active sweep, 0.0…1.0.
:SWEep:SPACing

[SOURce]:SWEep:SPACing?
This command enables
the
signal
generator linear or logrithmic sweep
modes. These
c
o
mmands
require
the
s
ignal
generator to be in step mode.
The instrument
uses
the
specified
start frequen
c
y,
stop frequency, and number of points
for
both
linear and log sweeps.

The
RF carrier is
modulated when you have set the
signal generator’s
AM modulation state
to
ON. Whenever amplitude modulation
is
enabled, the AM on
is
in the display.
