User Manual 9250
3-12 Portrayal
Channel 1, Auxiliary
Offset Adjustment
Equipment: Oscilloscope, waveform generator, x10 attenuator
Procedure:
64. Configure the waveform generator as follows:
65. Frequency: 1MHz
66. Function Ch1: Square wave
67. Function Ch2: DC
68. Amplitude Ch1: 200mVp-p (may vary depending on
the configured gain)
