In the above test setup, all cables, attenuators, and oscilloscope should have
bandwidth ratings of at least 2 GHz (and preferably > 10 GHz). The use of 40 dB
attenuator at the sampling scope vertical input channel will insure a peak input signal to
the sampling scope of less than 1 Volt, to avoid damaging the scope.
BASIC TEST ARRANGEMENT, WITH OUTPUT MODULES
For normal operation, one or both of the output modules will be installed on the outputs.
When using OUT1, the basic test arrangement is shown below:
