Edge count
Except for delay measurement, the measurements have the same settings and results
for analog and digital sources.
Delay measurement on digital channels is reduced to measure the time between two
subsequent rising or two subsequent falling edges.
See also Chapter 8.2, "Automatic measurements", on page 330.
14.5 Data export
The data of digital channels and parallel buses can be saved to file in the same way as
analog waveform data. One digital channel or bus per file can be saved.
If the data is written to XML or CSV files, the selected format is used. If the target file
format is BIN, you can save signed and unsigned binary data. The data format
"Signed" writes signed data; all other formats are saved as unsigned binary data.
The export of raw data is not available.
Export of a digital channel
If the data of digital channels is stored in BIN format, 1 bit is written for each sample. 8
data samples are written in 1 byte (data word). Thus, the file size is
File size = Number of samples / 8
For example, 100 MSa are written into a 12.5 MByte BIN file. After reading the file, you
have to extract the samples from the data words.
If saved to BIN file, the digital channel can be imported as reference waveform.
Export of a parallel bus
A parallel bus can be exported to file if "Enable bus" and "Show bus" are both activa-
ted, and the bus representation is "Comb".
All data formats can be saved to XML, CSV, and BIN files. If you save binary format to
XML or CSV, you can see the values of each line for each sample.
In BIN files, 4 Bytes are written for each sample.
