turns the plotter auto feed function on or off when in the
plot menu. It turns the printer auto feed on or off when
in the print menu.
brings the trace data in view on the display with one keystroke.
Stimulus values are not affected, only scale and reference
values. The analyzer determines the smallest possible scale
factor that will put all displayed data onto 80% of the vertical
graticule. The reference value is chosen to put the trace in
center screen, then rounded to an integer multiple of the scale
factor.
enables and disables auxiliary channels 3 and 4. A full
error correction must be active to enable the auxiliary channels.
allows you to monitor the analog bus nodes (except nodes
with external equipment. lb do this, connect
the equipment to the AUX INPUT BNC connector on the rear
panel.
makes averaging factor the active function. Any value up to
999 can be used. The algorithm used for averaging is:
A(n) = +
(1 l/F) x 1)
where
A(n) = current average
S(n) = current measurement
F = average factor
turns the averaging function on or off for the active channel.
“Avg” is displayed in the status notations area at the left of the
display, together with the sweep count for the averaging factor,
when averaging is on. The sweep count for averaging is reset to
1 whenever an instrument state change affecting the measured
data is made.

averaging starts at 1 and averages each new sweep into the
trace until it reaches the specified averaging factor. The sweep
count is displayed in the status notations area below “Avg” and
updated every sweep as it increments. When the
averaging factor is reached, the trace data continues to be
updated, weighted by that averaging factor.

is used to access three different noise reduction techniques:
sweep-to-sweep averaging, display smoothing, and variable IF
bandwidth. Any or all of these can be used simultaneously.
Averaging and smoothing can be set independently for each
channel, and the IF bandwidth can be set independently if the
stimulus is uncoupled.
