BERT block
In this block an integrated bit and block error rate tester can be set. The bit error tester
makes it possible to evaluate a signal demodulated and decoded by a DUT by measuring
the bit error rate. The data used to drive the DUT can be generated by the R&S SMU or
an user-defined external source. In addition, the block error rate measurement can be
used to verify CRC checksums.
The TOGGLE ON/OFF key switches the active function(s) of the block on or off. The
functions (BERT and BLER) are activated in the respective menus.
3.4 RF Section
The RF section of the R&S SMU may also contain two paths.
An RF path is configured by installing a frequency option that comprises all required
modules.
One of the following options must be installed.
Frequency options (Path A)
●
R&S SMU-B102 (up to 2.2 GHz)
●
R&S SMU-B103 (up to 3 GHz)
●
R&S SMU-B104 (up to 4 GHz)
●
R&S SMU-B106 (up to 6 GHz)
Frequency options (Path B)
●
R&S SMU-B202 (up to 2 GHz)
●
R&S SMU-B203 (up to 3 GHz)
RF path B can be I/Q-modulated only if the baseband section is equipped with two Base-
band Main Modules R&S SMU-B13.
In addition, each RF path can be equipped with
●
high-power option for higher output levels (R&S SMU-B31/B36)
For detailed information on available options, refer to the R&S SMU data sheet and the
R&S SMU Configuration guide.
Up-to-date information is available at R&S SMU homepage on the internet http://
