Logic Test Probe
Top of the line pen sized TL/CMOS logic
probe plus logic pulser
Large LEDs and pulse memory
Logic Test: detects pulses as narrow as
10nS at up to 50MHz, compatible with
TTL (DTL, HTC) or CMOS
Logic pulse function: used to
inject a single pulse, a low-repetition
rate pulse (0.5Hz) or a high repetition
rate pulse (400Hz)
Logic thresholds:
TTL "1" (HI LED) > 3.0±0.25VDC,
Logic "0" 9LO LED) < 0.75±0.25VDC
CMOS "1" (HI LED) > 60% Vcc±5%,
Logic "0" (LO LED) < 15% Vcc±5%
Output current 100mA sink/source (5mA square wave output)
with low 1M sync input impedance to ensue that circuit under test is
not loaded down. Pulse width 100µs.
Pulse has external sync for synchronization with computer clock circuit
