DDS-based High-Speed Switching Signal Generator Board for PCI
Model FSW01-PCI |
FSW01-PCI 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 2.5MHz to 400MHz in 0.23Hz step
and the frequency can be switched within 1uS. Also, the signal amplitute can be controlled
with more than 30dB and switched within 1uS. The output level is maximum +10dBm.
In case the accurate 10Mhz clock is available externally, the frequency stability can be
improved.
