---Digital Modulator/Calibrator

The Hallux-PCI Digital Modulator/Calibrator is a DSP (Digital Signal Processing) based multifunction card designed around the PCI form factor. Modulation modes are software selectable to support FM, FSK, PM and BPSK modulation techniques. The product also has the ability to be a baseband signal generator for triangle, square and sawtooth waveforms. Up to eight internal VCOs can be individually configured as either modulator or calibrator channels with any combination of channel types and modulation schemes. All configured channels are digitally summed together creating a single multiplex output. Modulator channels are modulated with user supplied data connected to the card through BNC cables. Calibrator channels are configured for modulation type, frequency, deviation and autostep profile. Select from FM, FSK, PM or BPSK modulation mode for each channel. Fully programmable, all IRIG 106-93 CBW and PBW FM subcarriers are supported as well as nonstandard frequencies with a carrier frequency range of 250 Hz to 5 MHz.
