 T166B Multi-frequency Tone Generator |
|
The T166B Multi-frequency Tone Generator is designed for use in ESS type office or PBX’s, or in any office where a control lead or a dry circuit (no battery during idle) cannot be provided. The test line operation is initiated by application of ringing voltage to the pair assigned to the test line.
The T166B Multiple Frequency Reference Tone Generator is useful in making one-way transmission measurements where it is necessary to evaluate the frequency response characteristics of the line or trunk. The T166B test lines may also be arranged to provide a quiet termination which can be used to make noise measurements.
The T166B includes a stable reference tone generator, designed to supply up to ten tones all cycling in any sequence. Tones in the frequency range of 200 to 5000 Hz can be provided.
See Data Sheet for more information.
