6.3 Reference Waveforms
To compare waveforms and analyze differences between them, you can display refer-
ence waveforms.
Reference waveforms are waveform data stored in the internal reference storages.
Four reference waveforms are available and can be displayed: R1 to R4.
The display of a reference waveform is independent from the display of the source
waveform; you can change the vertical and also horizontal scales and positions. The
current scale values are shown in the waveform label of the reference waveform.
Short menu
The short menu shows the status of all reference waveforms.
1 = select a reference waveform
2 = display a reference waveform
3 = Reference waveform label with vertical and horizontal scale, reference number and source waveform
File format
Waveforms can be saved as reference waveforms. The file format is TRF. Files can be
saved to and loaded from internal memory or external USB flash device.
TRF is the specific binary format for reference waveforms of the R&S RTB2000. 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 RTB2000.
6.3.1 Using References
To create and display a reference waveform
1. To activate the reference waveform and open the "References" menu, press the
REF key twice.
