SQUARE WAVE RESPONSE.

a. Test equipment required: Oscilloscope (-hp-
Model 175A/1750B) and 10:1 Probe (-hp-
Model 10001A).
b. Connect CHANNEL A OUTPUT without a
load to the oscilloscope using the 10:1
Probe, and set the 3300A controls as
follows:
CHANNEL A function .................SQUARE
FREQUENCY dial ......................10
RANGE switch............................X10K
c. Verify: Rise and fall time

Test equipment required: Oscilloscope (-hp-
Model 175A/1750B) and 10:1 Probe (-hp-
Model 10001A).
Connect SYNC OUTPUT to oscilloscope
and set 3300A controls as follows:
Pulse should be > 10 volts peak-to-peak
and < 5 microsecond duration.
Test equipment required: DC Power Supply
(-hp- Model 723A) and Oscilloscope (-hp-
