The PR-21 is a versatile instrument for troubleshooting and analyzing logic circuits. Features include visual indication of pulse level and pulse presence, pulse memory, Plus an audible, two-tone, logic state indicator. The probe responds to pulses as narrow as 30NS and pulse trains up to 20MHz, and is compatible with TTL, dtl, RTL, htl, CMOS and mos. It is also compact and light weight. Three color-coded LEDs indicate pulse presence and high/low logic States. Visual indication is complemented by audible tones of two distinctly different frequencies to distinguish the logic States easily. The PR-21 logic probe is a valuable servicing aid, especially when used in conjunction with the pr-31 logic Pulsar.
