Pulse Generator 202 MAX

The PSG-MAX is a completely different animal from the PSG-202. The operating characteristics have been optimized to produce a higher output and much shorter pulse duration than the PSG-202.This does NOT mean that the PSG-MAX is a better signal generator than the PSG-202. It is simply a DIFFERENT signal generator with a sharper output and is not meant to replace the PSG-202. Many people DO NOT LIKE the output characteristics of the MAX, complaining that the output is excessive and sharp. But many people buy the MAX especially for this characteristic.


Like the PSG-202, the MAX has dual outputs, but each are completely independent and isolated from each other. Power output is alternated between the two channels so that both channels never have output at exactly the same time. Besides the interesting effect, this feature also allows for safer application under certain conditions.

The Frequency control on the PSG-MAX is an adjustment of the rate or cycle time. It can be adjusted to provide a very long off cycle time (for a slow pulse rate) to an extremely short off time (producing a very fast rate of pulses).

The PSG-MAX has a Pulse Grouping function. When the Pulse switch is on, the generator produces a train of "grouped" pulses. The Rate Control provides for a very wide range of effect for this function.

As with the PSG-202, the PSG-MAX also has quick disable buttons which can instantly turn off the output of either channel. A Green LED (light emitting diodes) is provided for each channel to indicate the on or off state. A Red LED is also provided for each channel to provide a visual indication of the approximate amount of power each channel is producing (the brighter the LED, the higher the output).

The PSG-MAX is powered by a ordinary 9 volt transistor radio battery. The design of this signal generator provides for an extremely long battery life, so no provision for an A.C. Adapter was necessary.

Note: If you're into TT or nipple work and have, or are planning to purchase, a PSG-MAX be sure to check out the Vacuum Electrode Cups.
