MIL-PRF-19500/505E

NOTES:

1. The input waveform is supplied by a pulse generator with the following characteristics: tr  20 ns, tf  20 ns,

Zout = 50 , PW = 23 s, duty cycle  2 percent.

2. The output waveform is monitored on a sampling oscilloscope with Zin  20 M, Cin  11.5 pF, tr  2 ns.

3. Resistors shall be noninductive types.

4. The dc power supplies may require additional by-passing in order to minimize ringing.
