Vector Signal Generator R&S SMIQ – Specifications
Modulation with coding
The table below shows the possible combinations of modulation with coding (X = combination possible).
Data generator (option R&S SMIQB11)
Programmable data memory for modulation data, envelope-control and trigger signals. The data generator can be operated
only in conjunction with the optional modulation coder (R&S SMIQB20).
