Output Pulse Monitoring Instrumentation

The original Febetron manual recommends using an oscilloscope with a P-11 phospher Cathode-Ray tube, such as is found on the Tektronix Model 519. Use of other, more modern, oscilloscopes is certainly possible, but is important to note that the instrumentation of a Febetron system requires an oscilloscope with a rise time of not more than 2 to 3 ns and a sensitivity of 7 to 10 volts/cm. Obviously, the output pulse of the febetron system is of such short duration (~50 ns) that some method for storing and later playing back the output signal is needed. This can be either traditional photographic or more modern digital storage methods.

A 75 volt capacitive divider is provided on the 2020 Pulser for sampling the ouput voltage of the aqueous resistive load. Prior to pulsing pulsed voltage monitoring equipment should be fully warmed up and stabilized.
