For example, at 200 ps/div and 10 divisions, the record length must be 500 points:
Max Rec Length 500 samples = (10 divs x 200 ps/div)
÷
4 ps/sample
Max Rec Length = 500 samples
Note
As implied from the operation just described, Resolution and the equivalent elements, Sample
Interval and Sample Rate, are derived and cannot be set directly. You can, however, check the
Resolution at anytime in the resolution readout. Also note that the front-panel RESOLUTION
knob actually adjusts the Record Length to increase sample density.
The previous discussion also assumes that Horizontal Scale is held constant. You can hold the
Sample Rate constant instead by clicking Hold Sample Rate constant on the Record Length tab of
the User Preferences control window.
Independent versus Shared Window
The instrument applies the same horizontal acquisition window to all channels from which it
acquires data. Unlike the vertical acquisition window that you size and offset independently for
each channel, the same time/div, resolution (record length), and horizontal position (from the same
trigger point) apply to all channels simultaneously. One trigger, from a single trigger source, will
locate a common horizontal acquisition window for all active channels, which you can shift in
parallel by setting the horizontal position control.
