Amplifier Tuning and Power Considerations
The TP1 is a precision pulse generator to safely tune power amplifiers (often called linear amps) at high power levels. It is also a calibrated burst generator simulating the average sound levels of the “human voice” when evaluating power amplifiers.
The TP1 provides a modulation envelope consisting of a 2.5 KHz burst with an adjustable duty cycle between 10 ms to 25 ms and rep rate of 20-50 Hz. The calibrated setting for a Crest factor of C-20dB is 10 ms and 25 Hz. This setting is repeatable and can be used as a standard when evaluating amplifier performance.
Specifications:
Burst Frequency: 2.5KHz +/- 200 Hz
Burst Duration: 10ms to 25 ms +/- 2 ms
Rep Rate: 20Hz to 50Hz +/- 5 Hz
Pulse Output Z: 600 ohms
Power Source: Microphone line or external 9-12 VDC
Pressing PTT enables pulse output. Releasing PTT reverts microphone to normal operation.
Aux In: suitable for Two Tone test generator such as
the PreciseRF model TTG
Requires a 12VDC Power Supply (wall ward) for stand alone operation (sold separately)
Optional universal male and female 8pin DIN microphone interface cables available. 
Compatible with most Elecraft, Kenwood, Icom and Yeasu transceivers (selected via internal DIP switch)
