"The Model 132A uses unique output circuitry to form the pulse. This method of pulse generation is a development of E-H and is the reason for the broad capabilities of the Model 132A. Basically, the latch is a bistable circuit with one stable state being zero volts output and the other stable state being some positive or negative output determined by the Amplitude and Polarity controls. The latch is triggered from one state to the other by a series of trigger pulses generated by the timing circuits. The latch changes in about 10ns, providing the fast rise and fall of the output pulse

One of the most important features of the latch circuitry is the freedom from all waveform adjustment controls. The output pulse is extremely clean and fast under all conditions of amplitude, repetition rate, pulse width, etc., with no 'trimming up' of the pulse required. The only waveform control is the front panel rise time control which is provided as a convenience to the user.

The timing circuitry of the Model 132A is entirely solid-state, insuring reliable operation indefinitely. A vacuum tube used in the output latch is a premium type rated for 10,000 hours life. In addition the Model 132A has been quality constructed to provide long trouble-free operation." (E-H, Catalog, 1972)
