Real-Time
The real-time mode sets the oscilloscope to acquire data in the real-time
acquisition mode. In this mode, all the data points that make up a waveform
come from one trigger event.
The real-time mode is typically used to capture signals that happen either
once or infrequently. The oscilloscope can simultaneously capture 2
single-shot acquisition on all channels at sampling rates up to 2 GSa/s. This
allows the capturing of simultaneous, nonrecurring, or low-repetition-rate
events at the same time.
In the real-time mode, you can set the sample rate to auto or adjust, and you
can vary the record length. When real time is selected, three additional
softkeys are displayed: sequential key, record length, sample clock. Each of
these keys are discussed later in this chapter. You can calculate the amount
of time captured in memory in the realtime mode using the following formula.
Time = record length + sample rate

the oscilloscope, for additional information on repetitive and real-time
sampling.
