Figure 11.3 Schematic diagram of storage depth
The relationship between storage depth, sampling rate and horizontal base gear is as
follows:
MDepth = SRate * TSCale * HDivs
MDepth: storage depth, in unit pts.
SRate: sampling rate, in unit Sa/s.
TSCale: horizontal time base gear, in unit s/div.
HDivs: the number of grids in horizontal direction, in unit div.
Therefore, at the same horizontal time base gear, high storage depth can ensure high
sampling rate.
Click Auxiliary > Acquisition to open the acquisition menu.
Select a storage depth. The default storage depth is 4K. Click the storage depth or down
arrow to select another storage depth.
Optional storage depth: 4K, 20K, 200K, 2M, 4M, or 8M.
In single-channel mode, the maximum storage depth is 8M.
In double-channel mode, the maximum storage depth is 4M.
In triple or quadruple-channel mode, the maximum storage depth is 2M.
Tip:
Under sAutomatic mode, the oscilloscope automatically selects the storage depth based
on the current sampling rate.
11.5 Interpolation methods
Under real - time sampling, oscilloscope obtains discrete samples of the displayed
waveform. In general, waveforms displayed by dots are difficult to observe. In order to
increase the visibility of the signal, the digital oscilloscope usually adopts interpolation
display mode. Interpolation is a method of connecting sample points and calculating the
whole wave form from some points. For real-time sampling using interpolation, even if
the oscilloscope only collects a few sampling points, interpolation can be used to fill the
gaps between points and reconstruct accurate waveforms. Interpolation methods
include sine wave interpolation, step interpolation and linear interpolation.
