HF Compensation
Before shipment from the factory, this probe has been correctly adjusted to
Yokogawa’s digital oscilloscope DL1740 with the signal generator having 300 ps-
rise time so that the optimum square waveform is obtained. If the HF adjustment
needs to be performed, two trimmers (T1 and T2, see also the following Figs.)
are used. The T1 trimmer is used to adjust the rise time while the T2 trimmer is
used to adjust the response time of the probe.
