Sampling Operation
Figure 5-2 shows the measurement sequence of this instrument.
Measurements are performed when the trigger event is received.
When each measurement is complete, the COMPLETE signal is output and the data output starts.
The measurement data is output to the display or interface.
If a sampling speed is faster than the transfer speed of an interface, the data cannot be output.
In this case, output the measurement data after acquiring all the measurement data in the data memory.
