Module Vertical Scale and Offset Controls
861xx series plug-in modules have front-panel vertical scale and offset controls which provide the same function as the vertical scale and offset controls that are located on the N1000A. Turn the vertical scale knob to adjust the sensitivity of the currently selected channel. Turn the offset knob to adjust the vertical position of the waveform on the display screen without modifying the waveform itself. The offset value represents an absolute value on the display.
