A-148

Module A-148 (Dual S&H) has two identical sample & hold modules, designed to produce ‘staircase’ voltages. The signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the S&H output.
The exact shape of the staircase depends on the sort of waveform at the sample input: NOISE or RANDOM signals produce random patterns; an LFO produces rising or falling staircase patterns.
Two LEDs for each S&H indicate the voltage (positive or negative) of the sampled signal.

Technical Specs.:

• Width: 4HP
