Acquisition and waveform setup
R&S

MXO 4 Series
108User Manual 1335.5337.02 ─ 05
The number of acquired waveforms is shown in the "History" dialog, when the history is
active.
Remote command:
ACQuire:SEGMented:MAX on page 441
Fast segmentation
If fast segmentation is enabled, the acquisitions are performed as fast as possible,
without processing and displaying the waveforms. When acquisition has been stopped,
the data is processed and the latest waveform is displayed. Older waveforms are
stored in segments. You can display and analyze the segments using the history.
Remote command:
ACQuire:SEGMented:STATe on page 441
Segments (N-Single)
See "N-single/Avg count" on page 105.
Max available
Shows the maximum number of segments that can be captured with current sample
rate and record length settings.
6.2.4 High definition mode
The high definition mode increases the numeric resolution of the waveform signal by
using digital filtering, leading to reduced noise. The higher vertical resolution reduces
quantization noise and acquires waveforms of higher accuracy with finer details of the
signal to be seen. The high definition is also applied to the digital trigger, thus the
R&S MXO 4 can trigger with the same high resolution with which they can display sig-
nals.
The maximum numeric resolution in high definition mode is 18 bit. The actual value
depends on the selected bandwidth. Increasing the bandwidth reduces the resulting
digital resolution. For dependencies and details, refer to the R&S MXO 4 specifica-
tions.
The number of vertical resolution bits defines the number of vertical levels that the
acquisition samples are mapped to (quantization). For example, 16 bits of resolution
represent 65536 voltage quantization levels, while 8 bits of resolution represent only
256 voltage levels. The waveform values are recorded with a word length of 16 bit,
except for peak detect decimation.
