RIGOL Chapter 7 Digital Channel
7-4 DS1000Z User Guide
To Set the Waveform Display Size
Press WaveSize to open the waveform size selection list. You can use or press
WaveSize to set the waveform display size of the channel currently turned on to S
(small) and L (large).
Note:
L (large) can only be used when the number of channels currently turned on is
no more than 8.
You can also directly rotate VERTICAL
SCALE to set the waveform display
size. Turn clockwise to set it to L; turn counterclockwise to set it to S.
Reorder Setting
Press 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.
Auto View
Press Auto View and the analog channel waveform and digital channel waveform
will be displayed respectively on the upper and lower half screen respectively. By
default, the digital channel waveforms are displayed on the upper half screen and the
analog channel waveforms are displayed on the lower half screen.
Note: When the number of channels currently turned on is more than 8 or the
waveform display size is L, Auto View is grayed out and disabled.
To Set the Threshold
Press Threshold to enter the threshold setting menu. 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.
The threshold levels of channels D7-D0 and channels D15-D8 can be set separately
according to the need. You can select a preset value or user-defined threshold. The
range of the user-defined threshold is from -15.0 V to +15.0 V.
Press Low Type to open the threshold selection list to select the threshold of D7-D0.
The selectable preset values include TTL (1.40 V), CMOS (2.50 V), ECL (-1.30 V),
PECL (3.70 V), LVDS (1.20 V) and 0V. You can also press D7-D0 and use to set
