1. Hold the 1710J-Series Waveform Monitor REF button in until the calibrator
signal is displayed.
2. Turn off the HORIZONTAL MAG and select 2 LINE sweep.
3. Use the HORIZONTAL position control to place the first falling calibrator
transition on the 10
m
s graticule mark (the timing mark on the left side of the
graticule that goes completely through the blanking line). See Figure 6–2.
