To Set the Waveform Display Size
Press LA  WaveSize, rotate to select the desired display size and the press
down . You can also press WaveSize continuously to switch among S (small), M
(medium) and L (large).
Note: L (large) can only be used when the number of channels currently turned on is
no more than 8.
Reorder Setting
Press LA  ReOrder to select the waveform order mode on the screen of the
channels currently selected. You can select “D0-D15” or “D15-D0” and the default is
“D0-D15”.
 D0-D15: the waveforms on the screen are D0-D15 from top to bottom.
 D15-D0: the waveforms on the screen are D15-D0 from top to bottom.
To Set the Threshold
Press LA  Threshold to enter the threshold setting menu. The threshold levels of
channels D7-D0 and channels D15-D8 can be set separately. When the voltage of the
input signal is greater than the threshold currently set, it is treated as logic 1;
otherwise, it is treated as logic 0.
Press Type to open the threshold type selection list to select a preset value or user.
 The preset values include TTL, 5.0V CMOS, 3.3V CMOS, 2.5V CMOS, 1.8V CMOS,
ECL, PECL, LVDS and 0V. After selecting a preset value, press AppToD7-D0 to
apply the threshold level to channels D7-D0 and press AppToD15-D8 to apply
the threshold level to channels D15-D8.
 When “User Def” is selected, press D7-D0 and D15-D8 and use to set the
desired thresholds respectively. The range is from -20.0 V to +20.0 V.
