Analyzer Functions
defines the standard type to be a load, but with an
arbitrary impedance (different from system Z0).
sets the sequence bit in the Event Status Register, which
can be used to generate a SRQ (service request) to the
system controller.
turns the plotter auto feed function on or off when in the
define plot menu. It turns the printer auto feed on or off
when in the define 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.
allows you to monitor the analog bus nodes (except nodes
1, 2, 3, 4, 9, 10, and 12) with external equipment. To 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:
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.
At the start of the averaging or following
, 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 specified averaging
factor is reached, the trace data continues to be updated,
weighted by that averaging factor.
