As modular instruments continue to grow rapidly in popularity, many test development engineers are realizing the advantages offered by the small, flexible form factor of PXI-based systems. As part of our commitment to offer products across multiple popular architectures, SignalCore offers the SC5505A, a 1 slot, 3U, PXI Express 25 MHz to 6 GHz dual channel CW signal source. The channels provide independent frequency generation from 25 MHz to 6 GHz in frequency steps of 1 Hz. Both channels have a common internal 10 MHz TCXO reference, which can be phase locked to an external source for frequency synchronization.
The SC5505A is designed with the intent of being paired up with SignalCore IQ modulators and demodulators such as the SC5412A and SC5312A respectively, to form RF transceivers. It also serves well as LO sources for multiple single stage downconverters or a dual stage downconverter. Due its low spurious content and low phase noise, it is an ideal choice as a clock source for fast DAC and ADC applications, especially for those that require variable sampling rates. Its compact size and instrumentation grade performance make the SC5505A an ideal RF source for many modern applications such as wireless test systems, radar, digital clocking, instrumentation, and both academia and military applications.
