Length Control - Agilent Technologies InfiniiVision 4000 X-Series User Manual

Save/Email/Recall (Setups, Screens, Data)
If the oscilloscope acquisition is stopped, data from the raw acquisition
record (which has more points than the measurement record) can be
written. Press the [Single] key to obtain maximum memory depth with
current settings. If enabled, serial decode data is saved.
When you want to save less than the maximum number of data points, a
1- of- N decimation is performed to produce an output whose length is less
than or equal to the requested length. For example, if there are 100k
points of data, and you specify a length of 2k, 1 of every 50 data points is
saved.

Length Control

The Length control is available when saving data to CSV, ASCII XY, or BIN
format files. It sets the number of data points that will be output to the
file. Only displayed data points are saved.
When Max Length is enabled, the maximum number of waveform data
points is saved.
The maximum number of data points depends on these things:
• Whether acquisitions are running. When stopped, data comes from the
