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. 48).
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 un-triggered 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 1are
used to set the horizontal scale and position.
The Vertical VOLTS/DIV and the Vertical POSITION knobs of Channel 2
