A high-performance HF signal generator was designed by Southwest Research Institute (SwRI) as part of the test equipment for a specialized HF receiver. The generator is capable of producing up to 250 different signals in any 1 MHz band within the 3 to 30 MHz HF band. The transmitted signal or signals are truly arbitrary, produced at an IF range of 0.5 to 1.5 MHz, with a DAC update rate of 5 million samples per second.
Custom software was also developed to facilitate signal creation within certain parameters. Each signal had unique
The system achieved 75 dB SFDR, with a THD of 70 dB and a noise floor of 85 dB below full power.
