Optical Electronics 5893 peak sense-and-hold analog memory module senses input peaks of AC waveforms and produces smooth DC output voltage for driving 21/2 -digit digital voltmeter. Output of 5893 is divided by about 10 to give 1-V full-scale output for meter. External capacitor used with parallel resistor provides time constant required for steady display on DVM. Response time is 4 s for input change from 10 V to 0 and less than n s for rise from 0 to 10 V. Useful bandwidth is 20 Hz to 2 MHz. HOLD switch is operated when peak reading on meter is to be held several minutes.- Digital Peak Reading AC Voltmeter, Optical Electronics, Tucson, AZ, Application Tip 10259.
