DDS-based High-Speed Switching Signal Generator Board for ISA
Model FSW01-ISA |
FSW01 is a high-speed switching signal generator board with wide band clock source
utilizing DDS(Direct Digital Synthesizer) technique.
It provides sine wave signal output from 10MHz to 200MHz in 0.1Hz step
and the frequency can be switched within 1uS. Also, the signal amplitute can be controlled
with more than 30dB and switched within 10uS. The output level is maximum +10dBm.
In case the accurate 10Mhz clock is available externally, the frequency stability can be
improved.
