Use the probe adjust output on the oscilloscope or a pulse generator (less than
1
ns rise time) for full bandwidth adjustment.
1. Make sure that the trimmers T2 and T3 are in a center position.
2. Set the timebase of the oscilloscope to 5
ns/div.
3. Start the RF adjustment with trimmer T3. Turn it until the peak of the adjusta-
ble pulse response reaches the end level without any overshoot.
4. Turn trimmer T2 in the same way, but accept a small overshoot for the first
few nanoseconds.

After adjustment, we recommend sticking the label again to avoid confusion of the
trimmers.
