No. of Averages
Defines the number of waveforms used to calculate the average waveform, if "Acquire
Mode" = "Average". The higher the number, the better the noise is reduced.
To restart the average calculation, press the CLEAR SCREEN key.
Remote command:
ACQuire:AVERage:COUNt on page 263
ACQuire:AVERage:RESet on page 264
Nx Single
Sets the number of waveforms that are acquired with a SINGLE acquisition.
Remote command:
ACQuire:NSINgle:COUNt on page 251
Roll
Enables the roll mode.
The roll mode displays the untriggered, continuous signal. The roll mode moves the
captured input data on the display from the right to the left. The instrument shows the
waveform immediately, without waiting for the complete acquisition of the waveform
record.
Remote command:
TIMebase:ROLL:ENABle on page 264
Interpolation
Selects the interpolation method if interpolation is required to get the defined record
length.
"Sin(x)/x"
Two adjacent ADC sample points are connected by a sin(x)/x curve,
and also the adjoining sample points are considered by this curve.
The interpolated points are placed on the resulting curve. This inter-
polation method is the default method. It is precise and shows the
best signal curve.
"Linear"
Two adjacent ADC sample points are connected by a straight line,
the interpolated points are placed on the line. You see a polygonal
waveform similar to the real signal, and also the ADC sample points
as vertexes.
"Sample-Hold"
The ADC sample points are displayed like a histogram. For each
sample interval, the voltage is taken from the sample point and con-
sidered as constant, and the intervals are connected with vertical
lines. Thus, you see the discrete values of the ADC.
