The Avtech model AV-1000-C is a 50 MHz, generalpurpose laboratory pulse generator providing amplitudes of 0 to +/-10 V. It also includes DC offset, variable rise and fall times, exceptionally low jitter, and operating convenience. ECL and TTL outputs (and their complements) are provided, making the AV-1000-C an ideal pulse source for both digital and analog applications, and for triggering those Avtech instruments which require an external trigger (i.e., modules and -PS units).
