Cushman CE24A

Light weight, rugged design, and battery operation make the CE-24A ideal for use at remote locations, as well as at equipment offices. Even where ac power is available, the battery operation is helpful because it avoids hum caused by ac power lines Applications include measurement of tones, noise, crosstalk, and frequency response in cable, open wire, or radio multiplex systems, Measurements can be made on V-F systems or carrier systems with only a few channels or as many as 960 channels. Residual phase jitter performance makes the CE-24A ideal for phase jitter measurements on transmission systems carrying telemetry or other data signals.

Features

Digital Frequency Display

Large, bright, five-digit LED display makes frequency easy Overflow indicator allows frequency to set to the maximum range of  5000 kHz with 10-Hz resolution.

Phase-Lock Stability

The CE-24A is phase locked in 100-kHz increments for CE-24A for greater stability. Accuracy is 1 x 10-5. A continuous mode for searching is also provided.

AFC (Automatic: Frequency Control)

Measurement errors due to residual drift and troublesome signal peaking are virtually eliminated by AFC which automatically locks onto and tracks incoming signals.
