Chapter 11 Waveform Record RIGOL
MSO2000A/DS2000A User’s Guide 11-3
capacity of the waveform memory is fixed, the more the number of points each
frame of waveform has, the less the number of waveform frames can be
recorded. Thus, the maximum end frame of waveform record is decided by the
memory depth currently selected. Please refer to the instruction in “Memory
Depth” to select the desired memory depth. In addition, the maximum number
of frames is also related to the on/off states of the digital channels.
Note
[1]
: Memory depth = Sample rate × Horizontal time base × Number of grids horizontally
on the screen; wherein, for MSO2000A/DS2000A, “Number of grids horizontally on the
screen” is 14. Therefore, when the memory depth is set to "Auto", the maximum end frame of
waveform record is also related to the “Sample rate” and “Horizontal time base”.
Table 11-1 Memory Depth and Maximum Number of Frames (In this example,
only a single channel is turned on)
Memory Depth Maximum End Frame
14 k points None of the digital channels is turned on: 8128
One or more digital channels are turned on: 4088
140 k points 508
1.4M points 63
14M points 7
56M points 2
