"En
HR" Each acquisition is done in high resolution mode, and the minimum
and maximum values over some consecutive acquisitions build the
envelope.

No. of Averages
Defines the number of waveforms used to calculate the average waveform. 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

Nx Single
Sets the number of waveforms that are acquired with a [Single] acquisition.
Remote command:
ACQuire:NSINgle:COUNt
on page 434
Roll
Enables the automatic roll mode. The instrument switches to roll mode if the Time
Scale is equal or slower than Start Roll Time .
The roll mode displays the untriggered, continuous signal, and moves the captured
input data on the display from the left to the right. The instrument shows the waveform
immediately, without waiting for the complete acquisition of the waveform record. The
record length is set automatically ("Auto" mode). Some math functions are non-calcula-
ble if roll mode is active.
You can use the horizontal and vertical zoom in roll mode if the acquisition is stopped.
Remote command:
TIMebase:ROLL:AUTomatic
on page 458
Start Roll Time
Sets the limit timebase for the roll mode. The instrument switches automatically to roll
mode if:
●
the Time Scale exceeds the value given here.
●
the roll mode is activated ( Roll ).
Remote command:
TIMebase:ROLL:MTIMe

Interpolation
Selects the interpolation method if interpolation is required to get the defined record
length.
