TDS 500D, TDS 600B, & TDS 700D User Manual

To change the DPO display style, do the following steps:
1. Press DISPLAY ➞ Settings (main) ➞ Display (pop-up) ➞ Mode (main) ➞
DPO (pop-up) ➞ Style (main).
2. Select between Vectors and Dots in the side menu. (Dots display is the
factory default setting.)
3. Select between Infinite Persistence, Variable Persistence, and No
Persistence in the side menu. (Variable Persistence is the factory default
setting.)
Infinite and variable persistence are explained on page 3–41. The No
Persistence setting is available only in DPO mode. No Persistence erases the
display each time a new waveform array is displayed.
4. If you select Variable Persistence, use the general purpose knob or keypad
to adjust the persistence time (decay rate).
To change the DPO readout options, do the following steps:
1. Press DISPLAY ➞ Settings (main) ➞ Display (pop-up) ➞ Mode (main) ➞
DPO (pop-up) ➞ Format/RO (main).
2. Toggle Display T @ Trigger Point, Trigger Bar Style and Display
Date/Time in the side menu to the settings desired.
DPO adds three intensity settings that set the brightness and contrast of
displayed images. To set the intensity do the following steps:
1. Press DISPLAY ➞ Settings (main) ➞ Display (pop-up) ➞ Intensi-
ty (main) ➞ DPO Brightness or DPO Contrast (side). Enter the intensity
and contrast values with the keypad or the general purpose knob. Both
controls are ignored if Color Mapping is set to Percentages. Higher
brightness settings result in less frequent events being more easily seen. Low
contrast settings make less frequent events display at the same brightness as
frequent events. High contrast settings make less frequent events display at
lower brightness than frequent events.
2. To automatically set the brightness maximum to the value of the most
frequent event, press DISPLAY ➞ Settings (main) ➞ Display (pop-up) ➞
Intensity (main). Then toggle AutoBright (side) to ON. Off lets the
displayed brightness depend on the trigger rate, creating a display like an
analog oscilloscope.
