Informatie
FEATURES
DUAL TRACE FEATURES
Dual Trace
Model 2120 has two vertical input channels for displaying
two waveforms simultaneously. Selectable single trace
(either CH 1 or CH 2) or dual trace. Alternate or chop sweep
selectable at all sweep rates.
Sum and Difference Capability
Permits algebraic addition or subtraction of channel 1 and
channel 2 waveforms, displayed as a single trace. Useful for
differential voltage and distortion measurements.
CRT FEATURES
Rectangular CRT
Rectangular CRT with large 8 x 10 centimeter viewing area.
Convenience
Trace rotation electrically adjustable from front panel. 0%,
10%, 90%, and 100% markers for rise time measurements.
VERTICAL FEATURES
High Sensitivity
5 mV/div sensitivity for full bandwidth. 1 mV/div
sensitivity with PULL X5 at reduced bandwidth.
Calibrated Voltage Measurements
Accurate voltage measurements (3%) on 10 calibrated ranges
from 5 mV/div to 5 V/ div. Vertical gain fully adjustable
between calibrated ranges.
SWEEP FEATURES
Calibrated Time Measurements
Accurate (±3%) time measurements. Model 2120 has 19
calibrated ranges from 0.5 s/div to 0.5 |is/div. Sweep time
is fully adjustable between calibrated ranges.
X10 Sweep Magnification
Allows closer examination of waveforms, increases maximum
sweep rate to 50 ns/div.
TRIGGERING FEATURES
Two Trigger Modes
Selectable normal (triggered) or automatic sweep modes.
Triggered Sweep
Sweep remains at rest unless adequate trigger signal is
applied. Fully adjustable trigger level and (+) or (-) slope.
AUTO Sweep
Selectable AUTO sweep provides sweep without trigger input,
automatically reverts to triggered sweep operation when
adequate trigger is applied.
Five Trigger Sources
Five trigger source selections, including CH 1, CH 2, ALT,
EXT, and LINE. In ALT mode, each waveform becomes its own
trigger (alternate triggering).
Three Trigger Coupling Choices
Selectable AC, TV H (Line), or TV V (Frame) trigger coupling.
Video Sync
Frame (TV V) or Line (TV H) triggering selectable for
observing composite video waveforms.
OTHER FEATURES
X-Y Operation
Channel 2 can be applied as horizontal deflection (X-axis)
while channel 1 provides vertical deflection (Y-axis).
Built-In Probe Adjust Square Wave
A 0.2 V p-p, 1 kHz square wave Generator permits Probe
compensation adjustment.
Channel 1 Output
A buffered 50Q output of the channel 1 signal is available
at the rear panel for driving a frequency Counter or other
instruments. The output is 50 mV/div into 50Q.
Supplied With Two Probes Low Boy Configuration
Low profile housing saves bench space and allows
Oscilloscope to be carried like a briefcase.
