Acquisition Modes
Peak Detect - High frequency and
random glitch capture. Captures glitches of 10 ns using acquisition
hardware at all real-time sampling rates.
Sample - Sample data only.
Envelope - Max/min values acquired
over one or more acquisitions, selectable from 2 to 2000, infinite.
Average - Waveform averages selectable
from 2 to 10,000.
Hi-res - Vertical resolution improvement
and noise reduction on low-frequency signals, e.g. 12-Bits at 10 ms/div
and slower. Enhanced vertical resolution (>12-Bits) for noise
reduction, on low frequency signals. Make precise low-level signal
measurements (up to 5 µV) with differential amplifier
(ADA400A).
Time Base System
Time Bases - Main, Delayed.
Time/Division Range - 1 ns
to 20 s/div.
Time Base Accuracy - 0.015% over
any interval >1 ms.
Record Length (Real Time and Equivalent
Time) - Sample points per channel: 500 to 120,000 points (with
Opt. XL).
Pre-trigger Position - Selectable
from 0 to 100% of record.
Triggering System
Triggers - Main, Delayed.
Main Trigger Modes - Auto, Normal,
Single Sequence.
Delayed Trigger - Delayed by time
or events.

20 s.
Events Delay Range - 2 to 10,000,000
events.
External Rear Input - >1.5 kilohm;
Max input voltage is ±6 V (DC + AC peak).
Video Trigger Types - NTSC, PAL,
SECAM and custom; TV field, field 2 or both, any line within
a field. Line rates -10 kHz to 64 kHz, interlaced, noninterlaced,
composite.
Video Trigger Sensitivity - 0.6
divisions of composite SYNC will achieve a stable display.
Display
Waveform Style - Dots or vectors.
Infinite and variable persistence from 250 ms to 10 s.
Gray Scaling - With variable persistence
selected, waveform points gradually decay through 16 levels
of intensity, providing "z-axis" information about rapidly
changing waveforms.
Update Rate - 200 ea. 500 point
waveforms per sec with infinite persistence mode selected.
Graticules - Full, grid, cross hair,
frame.
Format - YT and XY.
VGA Out - Drives VGA display
monitors.
Zoom
The zoom feature allows waveforms to be
expanded, compressed and positioned in both vertical and horizontal
axes. Allows precise comparison and study of fine waveform detail
without affecting ongoing acquisitions. When used with Hi-res or
Average acquisition modes, Zoom provides an effective vertical dynamic
range of 1000 divisions or 100 screens.
