• Save Seg — when data is acquired to segmented memory, you can
specify whether the currently displayed segment is saved or all
acquired segments are saved. (See also
"Saving Data from Segmented
Memory" on page 230.)
4 Finally, press the Press to Save softkey.
A message indicating whether the save was successful is displayed.
CSV Data
When the CSV data (*.csv) file format is selected, comma- separated values
for each displayed waveform and digital channel pod are saved as multiple
columns in a single file. Math FFT waveforms, whose values are in the
frequency domain, are appended at the bottom of the .csv file. Pod names
(for example, D0- D7) or waveform labels are used as column headers. This
format is suitable for spreadsheet analysis.
For CSV data, length "N" value- at- time measurements are performed
across the entire screen (using the measurement record data) for each
active source. Interpolation between measurement record data points is
performed as needed.
ASCII XY Data
When the ASCII XY data (*.csv) file format is selected, comma- separated
value files for each displayed waveform, digital channel pod, digital bus,
and serial bus are saved. For digital pods, an underscore (_) and the pod
name (for example, D0- D7) are appended to the specified file name;
otherwise, an underscore and the waveform's label are appended.
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.
