25. Persist
When the Persist function is used, the persistence display effect of the picture tube oscilloscope can be
simulated: the reserved original data is displayed in fade color and the new data is in bright color. With the F2
menu selection button, different persistence time can be chosen: 1sec, 2sec, 5sec, Infinite and Closed.
When the "Infinite" option is set for Persist time, the measuring points will be stored till the controlling value is
changed (see Fig. 42).
25. XY Format
This format is only applicable to Channel 1 and Channel 2. After the XY display format is selected, Channel 1
is displayed in the horizontal axis and Channel 2 in the vertical axis; the oscilloscope is set in the untriggered
sample mode: the data are displayed as bright spots and the sampling rate is 1MS/s and can not be changed.
The operations of all control knobs are as follows:
•
The Vertical VOLTS/DIV and the Vertical POSITION knobs of Channel 1 are used to set the
horizontal scale and position.
•
The Vertical VOLTS/DIV and the Vertical POSITION knobs of Channel 2 are used to set the
vertical scale and position continuously.
