Set 222A for "+" PULSE POLARITY;
40 nsec pulse width; 150 mV p-p as
monitored on oscilloscope.
c.
Monitor 222A pulse output with oscil-
loscope and set REP RATE for 10 Hz.
d.
Set 5304A Channel A controls as follows:
ATT EN switch to XI
AC-DC to DC
SLOPE to +.
LEVEL to PSET or adjust until a
stable count is displayed.
e.
5300A display should be approximately
10 Hz.
f.
Repeat step c with 222A repetition rates
of 10 kHz, 100 kHz, 1 MHz and 10 MHz.
