A Precise and Practical Test Instrument
So far, I have used 2 out of the three I ordered. 100% just right! Frequency and duty-cycle are right on, as confirmed by my 6.5 digit multimeter. You do need some finesse to mount it, though. Great addition to my lab.

Output voltage tracks the power supply voltage. With power supply at 5V peak voltage is 5 volts with a 45ns rise and 7ns fall as measured on a 500MHz scope. With power supply at 15V the peak output voltage is 15 volts with a rise of 53ns and a fall of 12ns.

Excellent Accuracy
Excellent square-wave generator at twice the price or more! All specs verified in our telecom shop. Below 200Hz the wave is not very square but has good edges. Usable duty cycle 10 - 90%. Rise time ~500ns. Nice looking display
