Description
This is the ra
nge of real-time rates, expressed in samples/second, at which a digitizer samples signals at
its inputs and stores the samples in memory to produce a record of time-sequential samples. (IEEE
1057, 2.2.1)

(Sin x)/x interpolationWaveform Interpolation
Waveform interpolation is activated for sweep speeds of 100 ns/div and faster.
This is the total number of samples contained in a single acquired waveform record (Memory Length in
IEEE 1057.2.2.1).

s is the maximum, total, long-term error in sample-rate or horizontal position time accuracy, expressed
in parts per million.

Horizontal Position Time
Ra
nge
The user controls the time from the trigger to the center graticule on the display with the Horizontal
Position knob.
The resolution of the Horizontal Position time is 1/25 of a horizontal division.
Horizontal Window
Display
The Window Zone enables a user to select a part of the display to be m agnified. The user controls the
location with the Horizontal Position knob and the width with the Sec/Div knob. Vertical cursors show the
selected zone. To magnify the zone, the user selects the window from the menu.
