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 SC5405A, a three-stage high dynamic range superheterodyne upconverter for PXI Express. Designed to convert low frequency broadband IF signals to higher RF signals, the SC5405A has 3rd order linearity and noise performance that rival direct-conversion devices, but without image and in-band LO leakages that are inherent to them. The SC5405A is also highly configurable to suit the intended application; the user may choose to set the device biased towards linearity or towards better signal-to-noise ratio (SNR), as an example.

The SC5405A is designed with the intent of being paired up with SignalCore downconverters to form transceiver pairs and are ideal for applications such as Record and Playback. As the IF frequencies are the same, the pair may also form a frequency re-allocator that would receive information on one band and transmit the same information on another. With an add-on feature,  the  SC5405A can be configured as a 1 MHz to 3.9 GHz sine-tone generator.
