Chapter 11 Waveform Recording
Tip
Maximum Number of Frames
In the waveform recording menu, Total Frames shows the the maximum number
of frames that can be recorded currently. As the waveform memory capacity is
fixed, more points per frame (namely the memory depth) results in a smaller
number of waveform frames. Thus, the maximum number of frames of waveform
recording is related to the "Memory Depth" currently selected (refer to "To Set
the Memory Depth"). In addition, the maximum number of frames is also
related to the on/off states of the digital channels, as shown in the table below.
Table 11-1 Maximum Number of Frames
Memory Depth
Interweave:
Non-interweave: 7 k points

Non-interweave: 70 k points
Interweave:
Non-interweave: 700 k points

Note: Memory Depth = Sample Rate × Horizontal Time base × Number of Grids
Horizontally on the Screen. For MSO4000/DS4000, the "Number of Grids
Horizontally on the Screen" is 14. Therefore, when the memory depth is set to
"Auto", the mximum number of frames of waveform recording is related to the
current "Sample Rate" and "Horizontal Time base".
