Description
This is the range 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 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).
2,500 samples per record.
5 ns/div to 50 s/div in 1–2.5–5 sequence
Sec/Div Variable function is not available for this product.
This is the maximum, total, long-term error in sample-rate or horizontal position time accuracy, expressed
in parts per million.
±50 ppm over any ≥1 ms interval.
Horizontal scale setting
5 ns/div to 10 ns/div
25 ns/div to 100 μs/div
250 μs/div to 10 s/div
25 s/div to 50 s/div
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.
The Window Zone enables a user to select a part of the display to be magnified. 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.
Horizontal position time range
-4 div * s/div to 20 ms
-4 div * s/div to 50 ms
-4 div * s/div to 50 s
-4 div * s/div to 250 s
