No serial or parallel bus is active.
If "PEAK DETECT" is set to "Auto", the instrument selects the best peak detection
mode depending on the time base and sampling rate. The minimum and the maximum
of each sampling interval are recorded as data pairs, and the other samples are discar-
ded. Thus the instrument can detect fast signal peaks at slow time scale settings that
would be missed with other acquisition modes.
HIGH RES.
The average of n captured sample points is recorded as one waveform sample. High
resolution reduces the noise, the result is a more precise waveform with higher vertical
resolution.
The following requirements must be met to activate the high-resolution mode:
●
Sampling rate is smaller than the maximum sampling rate (no interlace mode)
●
Peak detection is deactivated
●
No active logic probe
●
No serial or parallel bus is active
INTERPOLATION
Selects the interpolation method to display the acquired data points:
"Sin x"
Two adjacent waveform points are connected by a sin(x)/x curve, and
also the adjoining sample points are considered by this curve. This
interpolation method is the default method. It is precise and shows
the best signal curve.
"Linear"
Uses a line to connect acquired data points.
"Sample-Hold"
Allows a more precise assessment of the position for the acquired
data points. For each sampling interval, the Y-value of the sample
point is considered as constant, and the intervals are connected with
vertical lines. Thus, you see the discrete values of the ADC.
RECORD MODE
See
4.3.3 Record Modes
The R&S
RTC1000 provides several record modes, which combine the setting of the
sampling rate, the memory depth, and the waveform rate.
MAX. WFM. RATE
Memory depth and sampling rate are adjusted to obtain the maximum trigger repeat
rate. The oscilloscope displays the maximum number of acquisitions per second in the
signal window. Each column in the signal window displays a captured date. When peak
detection is activated, each column displays a pair of min/max values. The
R&S
RTC1000 displays a signal window of 600x400 pixels (without zoom), which
translates into 600 data points per acquisition. When peak detection is activated, 600
pairs of min/max values or 1,200 data values are displayed.
