Since the AVO-9H-B-P1B can generate pulses with subnanosecond rise times, it may
be necessary to use a sampling oscilloscope, rather than a real-time oscilloscope. In
this case, the test arrangement should be altered as shown below:
Since most sampling oscilloscopes have limited input amplitude ranges, attenuators are
required. Select appropriate attenuators for your oscilloscope.
When the output module is not used, a 50 Ohm load impedance is
required
for proper
test operation.
BASIC TEST ARRANGEMENT - WITH OUTPUT MODULE
To fully test the instrument, and for normal operation, the output module should be
connected as shown below:
