The probe is slower than the input pulse, so the measured rise time is slower. The
probe also introduces a small amount of ringing.
OUT2
When OUT2 is connected to a high-bandwidth sampling oscilloscope (using the
arrangement shown in the "BASIC TEST ARRANGEMENT, WITHOUT OUTPUT
MODULES" section), waveforms similar to the one shown below will be obtained:
Pulser settings: 10 kHz, +50V, 200 ns PW.
Scope settings: 10 V/div, 50 ns / div.
The next photo shows the same waveform, with a finer time scale (1 ns/div) to show the
very fast rising edge (< 0.5 ns rise time on a 20%-80% basis):
Pulser settings: 10 kHz, +50V, 200 ns PW.
Scope settings: 10 V/div, 1 ns / div.
