Description

To work with the block, install/update the support package RITM blocks.

Block BA-IS-XX RF9-PRODUCE-LFM It is used to reproduce a quadrature linear frequency modulation signal on an SDR transmitter.

# ampl — the amplitude of the signal in the 16-bit DAC code
scalar

Details

Data types	`Float64`
Complex numbers support	No

# begin_freq — the initial modulation frequency in mhz
scalar

Details

Data types	`Float64`
Complex numbers support	No

# linear_coef — the coefficient of linear frequency growth
scalar

Details

The coefficient of linear frequency growth in F0/NT, where F0 is the initial frequency, NT is the number of periods with the initial frequency.
