Peak Detect Mode
In Peak Detect mode at slower sweep speeds, minimum and maximum samples are kept
in order to capture infrequent and narrow events (at the expense of exaggerating any
noise). This mode displays all pulses that are at least as wide as the sample period (see
Table 1).
See also “Glitch or Narrow Pulse Capture” on page 112.
High Resolution Mode
In High Resolution mode, at slower sweep speeds extra samples are averaged in order to
reduce random noise, produce a smoother trace on the screen, and effectively increase
vertical resolution.
High Resolution mode averages sequential sample points within the same acquisition. An
extra bit of vertical resolution is produced for every factor of 4 averages. The number of
extra bits of vertical resolution is dependent on the time per division setting (sweep
speed) of the scope.
The slower the sweep speed, the greater the number of samples that are averaged
together for each display point.
High Resolution mode can be used on both single-shot and repetitive signals and it does
not slow waveform update because the computation is done in the MegaZoom custom
ASIC. High Resolution mode limits the oscilloscope's real-time bandwidth because it
effectively acts like a low-pass filter.
