Analog/Voice Test SetSource: International Data Sciences Inc.
Beside the normal selection of individual tones and levels, other transmit modes include a repeating 250-4000 Hz sweep, a standard 3-tone gain slope test, and a "quiet" mode where no signal is transmitted.
International Data Sciences Inc.3 measures both frequency and level, and the level measurement can be displayed in dBm, dBrn, and Vrms. The receiver can measure signal amplitudes in the rand of +12 dBm to –70 dBm with a resolution of 0.1 dBm. Filters included 3 Khz flat, C-Msg, and 1010 notch. A speaker with volume control monitors the received signal and push-to-talk voice.
