Digital Storage System
The digital storage offers the following features:
H
Sampling at a maximum rate of 100 megasamples per second with both
channels sampled simultaneously
Glitch-catching capabilities for glitch widths as narrow as 10 ns
H
Acquisition of waveforms in any of four acquisition modes:
SAMPLE,
AVERAGE, ACCPEAK,
and
PEAKDET
(peak detect is available only at
SECIDIV
settings slower than 2 ps)
H
Maximum stored record lengths per waveform of either 4096 bytes (4 K)
for single-channel acquisitions or 2048 bytes (2 K) for dual-channel
acquisitions
(ALT
or
CHOP)
H
Four calibrated storage time bases of
1,
2, and
5
s per division for
low-frequency signal acquisitions (Horizontal Mode
A
only) using
XI0
STORE ONLY
button
Compression of the
4
K
acquisition record into a 1
K
acquisition record
using the Variable
SECIDIV
control (4
K
Compress mode)
Storage of up to three
1
K
records (51 2 data points per waveform when
dual-channel records are stored) or one 4
K
record
(2
K
per waveform
when dual-channel acquisitions are stored) in the
SAVE REF
memory
H
Storage of up to 26 K of waveform records in up to 26 locations in
extended memory
H
Capability to move waveforms between
SAVE REF
memory-where
they can be displayed, measured, or replaced-and extended storage
memory which frees up
SAVE REF
memory for storing new waveforms
User Interface
An internal microprocessor provides front panel control and feedback on
control settings.
Front Panel Controls
-
This oscilloscope uses a combination of front-
panel buttons, knobs, and on-screen menus to control its many functions.
The front-panel controls are grouped according to function: vertical, horizon-
tal, trigger, setup, and acquisition.
Almost all
NON-STORE
(analog real-time) and
STORE
mode functions are
set using front panel controls, which allows them to be quickly adjusted.
Some setup functions, such as
SETUP ACQ
and
DISPLAY,
are set indirectly
using menus.
Display
-
An internal microprocessor reads the front-panel controls to
determine their settings and generates on-screen readouts of many of those
settings. Settings are displayed for the following controls:
VOLTSIDIV
knobs and
AC-GND-DC
switches for both channels
