The condition is best shown by the included pictures.
The first picture shows operation in the calibrate mode.
This CE-24A was tested to work by receiving local AM radio stations with a length of wire as an antenna. Lower sideband (LSB) voice communication signals were also heard on the 80 Meter Ham Radio band.
For operation as a low frequency receiver, connect a simple wire-type antenna to the input BNC coaxial connector. Set the input toggle switch to ‘unbalanced’ mode and adjust the Input Attenuator for the desired decade sensitivity range.
'Lowfers' are a growing set of low-frequency listeners, which are the counter-part of short-wave listeners. Place an Internet search to learn more.
Operational test modes are Upper Sideband (USB) and Lower Sideband (LSB). The primary application for this CE-24A is baseband multiplex work within analog microwave radio systems. This CE-24A can also be used for signal tracing in the IF strips of radio receivers during alignment and maintenance activities.
Cushman CE-24 A’s are also used for very low-frequency carrier signal tests by power companies. These signals are often superimposed directly on high voltage power lines for data, telemetry, protective relaying and telephony applications. Such signals below about 200 kHz can often be received on a simple wire antenna. Ce-24A’s can also be used for Electromagnetic Interference (EMI) detection and location.
