2. For the TDS1000-series (monochrome monitor), a dimmed

waveform indicates reference waveforms or waveforms with

persistence applied.

For the TDS2000-series (color monitor), reference waveforms

appear white and waveforms with persistence applied appear in

the same color as the Main waveform, but with less intensity.

3. A broken line indicates the waveform display no longer matches

the controls. This happens when you stop the acquisition, and

change a control setting that the oscilloscope is not able to apply

to the displaye d waveform. For example, changing the trigger

controls on a stoppe d acquisition causes a broken-line waveform.

Key Points

Persistence. The TDS1000- and TDS-2000 series oscilloscopes use

“dfm” at a “reduced intensity” for persistence.

With Persistence set to Infinite, record points accumulate until a

control is changed.

XY Format. Use the XY format to analyze phase differences, such as

those represented by L issajous patterns. The format plots the voltage

on channel 1 against t he vol tage on channel 2, where channel 1 is the

horizontal axis and channel 2 is the vertical axis. The oscilloscope

uses the untriggered Sample acquisition mode and displays data as

dots. The sampling rate is fixed at 1 MS/s.
