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.
