The integrated bit error rate and block error tester is configured and activated in the
"BERT" function block:
●
Bit error rate and block error measurement
see
Chapter 5.4, "Bit and Block Error Rate Measurements - BERT Block" ,
on page 180
The RF signal is configured and the analog modulations activated in the "RF/A Mod"
function block:
●
CW mode
see
Chapter 5.5.1, "Overview of RF Signal" , on page 199
●
List mode
see
Chapter 5.5.15, "List Mode" , on page 273
●
Sweep mode
see
Chapter 5.5.14.1, "Overview" , on page 260
●
Analog modulations
see
Chapter 5.5.11.1, "Overview" , on page 240
In the "I/Q-Mod" function block, I/Q modulation is possible with external analog signals
and internally generated baseband signals.
●
I/Q modulator
see
Chapter 5.6, "I/Q Modulation - I/Q Mod Block" , on page 282
Noise can be added to the baseband signal and the baseband signal can be impaired
before input into the I/Q modulator. It is therefore possible to output a baseband signal
with impairments via the I/Q-OUT outputs ("AWGN/IMP" function block). Impairment is
also possible during I/Q modulation ("I/Q Mod" function block).
●
Impairing the signal
see
Chapter 5.7.1, "Impairments" , on page 289
●
Adding noise
see
Chapter 5.7.2, "AWGN - Noise Generator" , on page 293
The baseband signal is available at the I/O outputs.
●
Output of the baseband signal
see
Chapter 5.7.3, "Output of the Baseband Signal - I/Q Out" , on page 301
The R&S SMJ offers various possibilities for generating digital modulation signals in
compliance with the definitions of digital standards or with characteristics which can to
a large extent be freely defined. The range of software options for this is being exten-
ded continuously.
