Automatic Arrangement Setting
Press ReOrder to select the waveform ordering mode of the channels currently
turned on. You can select “D0-D15” or “D15-D0” and the default is “D0-D15”.
 D0-D15: from top to bottom, the waveforms on the screen are D0-D15.
 D15-D0: from top to bottom, the waveforms on the screen are D15-D0.
To Set the Threshold
Press Threshold to enter the threshold setting menu. You can set the threshold of
the two channel groups independently according to your need for the threshold level
of the two channel groups (D7-D0 and D15-D8) can be adjusted independently.
When the voltage of the input signal is greater than the threshold currently set, it is
regarded as logic 1, otherwise logic 0.
Press LevelType to selecte preset values or user-defined.
The preset values include TTL, 5.0V CMOS, 3.3V CMOS, 2.5V CMOS, 1.8V CMOS, ECL,
PECL, LVDS and 0V. After any one of the preset values is selected, press
App-toD7-D0 to apply this threshold to the channels of D7-D0; press
App-toD15-D8 to apply this threshold to the channels of D15-D8.
After “User Def” is selected, press D7-D0 and D15-D8 respectively and use to
set the desired threshold.
