13.2.4 Waveforms
A waveform can be saved in two ways:
●
As a reference waveform for later use with R&S
RTM: REF key
See:
chapter 5, "Reference Waveforms"
●
As data in various formats directly to a USB flash drive for analysis by other means:
FILE > "Waveforms".
This way is described in the current chapter.
If you want to save many waveforms, you can assign the function to the PRINT key.
Infrequent save operations can be started from the "File" menu. See also:
ter 13.2.2, "Quick Access with PRINT key"
13.2.4.1
Waveform File Formats
Data of all waveforms - channel, reference, and math waveforms - is saved as a suc-
cession of values or pairs of values. Pairs of values are written as two consecutive single
values. Depending on the file format, only amplitude values are stored, or the amplitude
values are stored together with their time value, or frequency value in FFT mode.
With export/import, you can change the target file format and convert the data.
In order to reload waveform data as a reference waveform, it must be stored in TRF or
CSV format.
TRF Format
TRF is the specific binary format for reference waveforms of the R&S
RTM. It contains
amplitude values or pairs of values, time information (time of the first sample and the
sample interval) and current instrument settings. The data can be loaded as reference
waveform for further use on the instrument. It is not intended for analysis outside the
R&S
RTM.
CSV Format
In a Comma Separated Values text file, the waveform is stored in a two-columned table.
Columns are separated by a comma, and the lines are separated by line breaks
\r\n
(
0x0D 0x0A
). Values are listed in scientific notation.
