FWSDR - A firmware for turning the high-end digitizer ADQ14 into a
Software Defined Radio
In this issue SP Devices is pleased to announce the new firmware which
turns the high-end, multi-channel digitizer ADQ14 into a Software
- Software Defined Radio
- Phase noise measurements
- Zero-IF receiver
- Low-IF receiver
The FWSDR firmware includes complex mixer for I and Q signals which in
combination with decimation selects the frequency band of interest. The
decimation factor can be set from 2 up to 2^32 to match the bandwidth of
the input signal, and higher order decimation is perfect for accurate
noise analysis. The high image suppression of 125 dB enables frequency
selection with high precision.
DC-coupled ADQ14 models can be used with FWSDR in order to implement a
zero-IF receiver and for such configurations the digitizer is directly
connected to a wideband IQ demodulator IC.
For best linearity at higher frequency which is suitable for a high
IF-receiver, AC-coupled models can be used. The FWSDR also includes a
complex filter for implementing equalization and IQ-balancing functions.
The powerful Software Development Kit (SDK) makes it easy to implement
streaming applications with up to 3.2 Gbytes/s data transfer rate. Using
the SDK any radio standard is easy to implement.
