SPECIFICATIONS
Focusing control on front panel.
Screwdriver adjustments for beam centering.
ILLUMINATION — Brilliant image — may be photographed with ordinary commercial camera.
SENSITIVITY:
From 20 Hz–100 kHz:
27.0 Volts R.M.S. for 1 inch deflection
74.0 Volts R.M.S. for full screen image
From 20 Hz–90,000 kHz:
0.7 Volts R.M.S. for 1 inch deflection
1.9 volts R.M.S. for full screen deflection
SWEEP CIRCUIT: Linear "saw-tooth" oscillator, adjustable from 20–15,000 Hz. positively synchronized with voltage under test by special circuit. Binding posts also for external synchronization.
AMPLIFIERS: Horizontal and vertical. Linear from 20 Hz–90,000 kHz, ±10%. Amplifier gain is approximately 40.
The RCA cathode ray oscillograph, the "X-Ray of the engineer," can be used to interpret any phenomenon which can be represented electrically, as well as for the more common use of examining alternating current wave shapes, phase relations, or any intermittent electrical currents.
