I had no problems with the boards I constructed but I have had reports of the circuit not working. The 2N2369 transistors appears to be no longer available. I have no experience with using the circuit with 2N2369A or BSX20 devices. Ihave a report that is does not work with these devices likely due to insufficient voltage to breakdown. This module produces a pulse with a very fast rise time. Its main use is for testing oscilloscope rise-time and hence estimating bandwidth. For convenience the module is powered from a micro-usb socket. Most current oscilloscopes have a USB host socket that can provide the power needed. Connection to the oscilloscope will require a BNC-to-BNC adapter. A length of 50ohm coax should be used to extend the pulse so that rise-time may be measured.
