Gain Menu

Press the GAIN button to display the Gain menu shown in Figure 2-13. The current gain setting is displayed in the lower left corner of the screen. The gain setting is displayed in yellow if variable gain is active.

In variable gain modes, use the general purpose knob to set the gain. The variable gain modes work together with the fixed settings. For example, touch the 1x soft key, touch the Variable Gain soft key, and then turn the general purpose knob to select a setting of 1.50x. The vertical gain is 1.5. Now touch the 5x soft key. The gain is 7.50x (the product of 1.50 and 5).

NOTE. The variable gain range is from 0.25x to 14x. You cannot select values outside this range. Gain is only active in Waveform, Vector, Lightning, Eye, and Jitter modes.

In fixed gain settings, the vertical graticule appears with a calibrated scale. When variable gain is enabled in Waveform, Jitter, and Eye modes, the graticule appears without a scale. In Vector and Lightning modes, the targets move when fixed gain settings are changed, but do not move as variable gain is adjusted.
