For example, when the Waveform display is in Overlay mode, you can select
from 1 Line, 2 Line, 1 Field, or 2 Field sweeps. When that same display is in
Parade mode, only 1 Line and 1 Field sweeps are available.
3. After you press the SWEEP button to close the pop-up menu, you can press
the SWEEP button again to toggle the sweep between 1 Line and the last
selected sweep setting.
To set the horizontal
(sweep) magnification
The magnification function applies only to the Waveform, Lightning, Bowtie,
and ANC Data displays. The magnification settings for each display type are
independent of each other.
Set the Waveform, Lightning, or Bowtie horizontal (sweep) magnification. The
default magnification setting is 1x. Select a magnification setting by performing
the following actions:
1. Press and hold the MAG button to display the Magnification pop-up menu.
2. Use the arrow keys to select a magnification setting. The available
magnification options depend on which display mode is active:
■ For the Waveform and Bowtie displays, you can select from Best View,
10x, 20x, 25x, or 50x. The Best View setting optimizes the magnification
for the selected sweep mode. For 2 Line and 2 Field sweeps, the
magnification is optimized to show the blanking intervals. For 1 Line and
2 Line sweeps, the magnification is optimized to achieve a reasonable
scale factor.
■ For the Lightning display, the magnification controls H Gain (horizontal
gain). You can select from 2x, 5x, or 10x fixed magnifications and you
can enable Variable H Gain and then use the General knob or the up/
down arrow keys to adjust horizontal variable gain.
3. After you have selected a magnification setting, press the MAG button to
close the pop-up menu.
4. You can now press the MAG button to toggle the magnification between 1x
and the last selected magnification setting.
NOTE.
For the Lightning display only, when variable H Gain is enabled and
a magnification setting other than 1x is also selected, the magnification
settings are multiplied together. For example, if variable H Gain is enabled
and set to 1.2x, and a fixed magnification of 5x is also selected, the displayed
H Gain magnification will be 6x (5 × 1.2).
Set the ANC data display magnification.
When the ANC Data display is selected,
press the MAG button to toggle the size of the user-data display area.
The magnification function for the ANC Data display allows you to see more of
the user data at the bottom of the display or to see more of the listed data types at
the top of the display.
