voltage source mode
2. Close the protective cover.
3. CHECK for the ripple pulse noise within 30 mV
4. Remove the X1 probe.
Specifications:
H Each step is within 2 % of total output + 3 % of Step Amplitude + 2 mV.
H Less than 2 % variation between step amplitudes.
H With STEP MULTI .1X on, each step is within 4 % of total output + 5% of
step AMPLITUDE + 2 mV.
H With STEP MULTI .1X on, variation between step amplitudes is less than
5 %.
1. Change the following 371B setting:
