Capturing Data
Choosing the Sampling Mode
The osilloscope can operate in real-time or equivalent-time sampling modes.
You can choose the oscilloscope’s sampling mode in the Acquire menu (accessed
by pressing the [Acquire] front panel button).
To select the real-time sampling mode
In the real-time sampling mode, single waveforms are sampled at uniformly
spaced intervals. See Figure 28 .
Use the real-time sampling mode when capturing (non-repetitive) single-shot or
pulse waveforms.
The 1000B Series oscilloscopes provide real-time sampling rates up to 500 MSa/s
(when two channels are on) or 1 GSa/s (when one channel is on).
To select the Real-Time sampling mode:
1 Press [Acquire] .
2 In the Acquire menu, select Sampling to choose the “Real Time” sampling mode.
In the real-time sampling mode, when the horizontal scale is set to 20 ns or faster,
the oscilloscope uses sine(x)/x interpolation to expand the horizontal time base.
