Summary
Description
zontrol AC power to the instrument.
?nable/disable
zero mode (subtract baseline value from subsequent
readings).
<ey in zero value with data entry keys.
3nableidisable
50kHz or 500kHz analog filter.
.nitiate measurement
sequence when immediate
triggering
is enabled. Arm
xternal,
input signal, and other channel triggering.
start/stop XY analog output
data.
Select single or continuous
A/D arming.
jelect XY mode to allow data plotting:
CRT, oscilloscope,
plotter, or strip chart.
Select external triger
pulse, immediate,
input signal, or other channel as trigger
wurce. (Use uprange or downrange
to scroll through
sources).
jelect data source for XY analog output:
measurement
buffer, RAM, readings, or
[EEE buffer.
Program trigger delay (post or pre-trigger).
Program window
for XY analog output.
Select positive or negative edge for triggering
from input signal.
Program trigger threshold
when triggering
from input signal.
Program XY output horizontal
scaling factor.
Control future scanner module.
Set AC, DC or ground input signal coupling.
Program number of samples or measurement
duration.
Program sampling
frequency
or interval between samples.
Cancel IEEE-488 remote status, restore front panel operation,
return display to
normal.
Select channels 1 or 2, dual channel display, or scanner channels.
Enable/disable
autoranging.
Move uprange, mow cursor right (data entry), increment
sample number
(RECALL), move viewed data right (XY PAN), increment
scaling factor (XY
ZOOM),
select front panel program (OTHER), scroll through
modes (FILTER,
SOURCE, XY MODE,
XY DATA).
Move downrange,
move cursor left (data entry), move viewed data left (XY I'AN),
decrement buffer location (RECALL),
select front panel program (OTHER), scroll
through
modes (FILTER, SOURCE, XY MODE, XY DATA).
Add second function
to front panel keys (shifted modes marked in yellow).
Recall stored samples from measurement
buffer.
Obtain information
on programmed
operating
modes.
Reset instrument
to power-on
conditions
(same as SETUP 1).
Enter data into memory during
data entry process.
Cancel data entered into display during
data entry.
Enter data as reciprocal frequency
or time.
Enter numeric
data and time, frequency,
or voltage units.
Divide channel 1 by channel 2 (dual A/D module units only).
Subtract channel 2 from channel 1 (dual A/D module units only).
Access IEEE address, self-test, NVRAM

Display sample at trigger point.
Display peak-to-peak
value of measurement.
Display standard deviation
of measurement.
Display integral of measurement
in volt-seconds.
