Gain Menu
The GAIN menu allows you to expand the display vertically by set levels or to
vary it continuously. The expanded waveform lets you inspect a waveform
feature or more precisely position a cursor for a measurement.
Press the GAIN MENU button to access the Gain menu. Use the fixed bezel
buttons to select from the gain settings of X1, X5, X10, and Variable gain. Gain
is useful in all display modes except PICTURE mode. In Vector displays,
variable gain changes both horizontal and vertical gain equally. Lightning and
Diamond displays have both horizontal and vertical variable gain.
CLEAR MENU turns off all of the menu readout, except the VAR GAIN label.
Variable gain remains active as long as the front-panel GAIN indicator is lit.
To turn Gain off, press the GAIN button once (twice if the Gain menu is not
visible). When you quit the Gain menu, Variable gain returns to the calibrated
setting and Vertical gain returns to X1.
