Overview Control elements and resourcesTo set display format (Cont.)
To select the
format (Cont.)
XYZ. This format compares the voltage levels of the
CH 1 (X) and CH 2 (Y) waveform records point by point
as in XY format. XYZ requires Fast Acquisitions mode.
The displayed waveform intensity is modulated by the
CH 3 (Z) waveform record. XYZ format is not triggered.
A --5 division signal (including position and offset) on
CH 3 produces a blank screen; a +5 division signal
produces full intensity.

Using FastFrame
FastFrame is an acquisition mode that lets you capture many records in a larger
record, and then view and measure each record individually.
FastFrame lets you quickly capture multiple acquisitions in the acquisition
memory of a single channel. Figure 3--16 shows how FastFrame combines the
desired captured frames into one larger waveform. For example, FastFrame
would let you store 4000 frames (depending on the record length option
installed) of 500 samples each into one waveform.
FastFrame mode lets you jump to and view the frame that you select. Time
Stamps can display the absolute trigger time for a specific frame and the relative
time between triggers of two specified frames. FastFrame lets you compare
different waveforms. Math is available on each frame.
