FEATURES
HIGH FREQUENCY FEATURES Wide Bandwidth
Conservatively rated — 3 dB bandwidth is dc to 60 MHz for
Model 1 560; dc to 40 MHz for Model 1 540.
Fast Rise Time
Rise time is less than 5.8 ns for Model 1 560; 8.8 ns for
Model 1 540.
Fast Sweep
Maximum sweep speed (with x 10 MAG) of 5 ns/div far Model
1560; 10 ns/div for Model 1540 assures high fre quencies and
short duration pulses are displayed with high resolution.
Signal Dalay Line
Signal is delayed with respect to triggering to give at
least 20 ns visible delay. Permits viewing leading edge of
high frequency and fast risetime pulses.
DUAL TIME BASE FEATURES Dual Sweep Generators
A sweep gives normal weveform display, B sweep may be
operated at faster sweep speed to expand a portion of the
waveform.
5 Modes of Horizontal Display
Choice of A sweep only, B sweep only, A sweep with B sweep
portion intensified, alternating A and B sweep (trace
separation adjustable), and X-Y.
B Sweep Delay
Start of B sweep selectable from zero delay, triggerable
after delay, and continuous delay (starts immediately after
delay) modes. Delay adjustable from 0.2 to 10 times A sweep
time. Permits expansion of any portion of waveform.
DUAL/TRIPLE TRACE FEATURES Tripla Trace
Model 1560 has three vertical input channels for displaying
three waveforms simultaneously. Selectable single trace
(either CH 1 or CH 2), dual trace, or triple trace
operation. Alternate or chop sweep selectable at all sweep
rates.
Dual Trace
Model 1540 has two vertical input channels for displaying
two waveforms simultaneously. Selectable single trace
(either CH 1 or CH 2) or dual trace operation. 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.
Internal 8x10 division graticule eliminates parallax error.
High Brightness
Domed mesh type CRT with post deflection acceleration and
high brightness phosphors. High acceleration voltage1, 1 6
kV for Model 1 560, 12 kV for Model 1 540.
Conveyance
Variable scale illumination for easy viewing in darkened
area and for waveform photographs. Trace rotation
electrically adjustable from front panel. 0%, 10%, 90%, and
100% markers for rise time measurements.
