- 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 ...

Problem Solution
Upon installation,
the software says
that the receiver is
not found and
offers to run in
demo mode only.
WR-G39DDCe (USB models):
Check that receiver is turned on using the switch
located at the front of the device. The blue LED should
flash.
Compare the LED flashing pattern with the table
shown in Appendix C. If the flashing pattern is “5”
(meaning USB connected, driver not installed), please
reinstall the driver: Disconnect the receiver from the
USB port first and reinstall the software from the
supplied CD ROM. Then reconnect the receiver.
Windows should detect this and start the usual “new
hardware found” routine.
WR-G39DDCi (PCIe models):
Check that the PCI card is properly seated in the PCI
slot.
There may not be enough power available on the
PCIe bus, auxiliary power may be needed. This is
provided on a standard 6-way PCIe connector at the
rear of the card. This additional power supply is
particularly necessary for multi-channel installations,
where more than one WR-G39DDCi card is installed
in a single PC.
