The maximum sample rate allows you to have the maximum single-shot
bandwidth.
The real-time sampling mode is intended to capture events that happen
either once or infrequently. To accurately display infrequently occurring
events, you need to capture and display as much data as possible with a
single trigger. For example, use the real-time sampling mode for laser
applications, high-speed glitch capture in digital systems, eye diagrams, or
when looking for transient events.
Equivalent time
In the equivalent-time sampling mode, the waveform is reconstructed from
data points that are acquired from multiple trigger events. The
equivalent-time sampling mode has the following features:
•
8 bits of vertical resolution
•
Averaging of acquired data points to achieve vertical resolutions of up to
12 bits.
•
Maximum sampling rate of 500 MSa/s on each plug-in slot
•
Maximum system bandwidth
•
Ability to turn on or off averaging
•
Selectable record length
•
Maximum of 32K points for any equivalent-time waveform.
The equivalent-time sampling mode is intended for use on repetitive signals.
For repetitive signals, you can use the data acquired from multiple triggers to
reconstruct the waveform, which gives you a higher system bandwidth.
