- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

WiNRADiO G39DDC User’s Guide
8
The power input socket requires 12 V DC with a tolerance of ± 1 V. The power
adapter must be rated for a minimum of 2 A.
CAUTION: For best performance and safety, we recommend using only
the power adapter supplied by WiNRADiO, which comes included with
your receiver.
The antenna input is an SMA-type connector with 50 ohm impedance. The
USB interface is compatible with the USB 2.0 standard and serves to connect
the receiver to a desktop or a laptop computer.
WR-G39DDCi Internal (PCI Express) Receiver Models
The WR-G39DDCi model is particularly suited for compact desktop monitoring
stations and for multi-channel applications. The advantage of this model is in
that it comfortably “hides” inside a desktop PC, requiring no additional desk
space, no interface wiring and no power supply – it relies on power supplied by
the PC.
For details of the available connections on the PCI Express card, please refer
to Appendix E – G39DDCi PCIe Card Connections.
