10.2.2.3
BIN format
BIN files contain only binary amplitude values but no time values. Each value has a
word size of 8, or 16, or 32 bit, the word size is the same throughout the file.
You can set the word order: BIN MSBF saves data in Big Endian order - beginning with
the MSB (Most Significant Byte) and ending with the LSB (Least Significant Byte). BIN
LSBF saves data beginning with the LSB and ending with the MSB. Pairs of values are
listed as two subsequent single values, without any identification.
10.2.2.4
FLT format
FLT files contain amplitude values in float format, where a 32-bit float value is saved in
4 successive bytes.
You can set the word order: FLT MSBF saves data in big endian order - beginning with
the MSB (most significant byte) and ending with the LSB (least significant byte). FLT
LSBF saves data beginning with the LSB and ending with the MSB.
10.2.2.5
TRF format
TRF is the specific binary format for reference waveforms of the R&S
RTA4000. It con-
tains the amplitude value of each sample that is displayed on the screen (8 bit or 16 bit
long). For peak-detect waveforms, 2 values per sample are saved. The file contains
also 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
RTA4000.
