Description
PERF Mode
8-bit
Set the vertical resolution (A/D)
12-bit
14-bit (only for
XDS3102AP/XDS3202A)
This menu is only for XDS3000-A series.
When the sample rate <=250MS/s, ADC resolution is set to 12-bit by default;
When the sample rate >250MS/s, and both channels are turned on, ADC resolution is
set to 8-bit by default;
When the sample rate <250MS/s, and only one channel is turned on, ADC resolution
can be set to 8-bit or 12-bit in this menu.
Note: For XDS3102AP/XDS3202A, the selection of 8-bit, 12-bit or 14-bit is not affected by
sample rate.

Description
Intrpl
Sinx/x
Use sine(x)/x interpolation
x
Use linear interpolation
Interpolation method is a processing method to connect the sampled points, using
some points to calculate the whole appearance of the waveform. Select the appropriate
interpolation method according to the actual signal.
Sine(x)/x interpolation: Connect the sampled points with curved lines.
Linear interpolation: Connect the sampled points with straight lines. This method is
suitable to rebuild the straight-edged signals, such as square or pulse wave.
