v1 v2 40 40 The BER is calculated in real-time by the PHY. This test uses a feature of the PHY which allows the receiver to compare an incoming packet with a packet already stored in a local buffer. In this test, the refdes server sends a packet via Ethernet to both nodes. Node 0 transmits the packet via the OFDM PHY. Node 1 copies the packet to a local buffer, which the receiver uses for its BER comparison. The receiver only updates its BER counters for packets which are received with an error-free header (packets with header errors cannot be received, as the modulation and length fields can't be trusted). 41 41 42 The independent variable in both tests is transmit power at node 0, swept over a range of 60dB. The power is controlled by setting the gain applied by the variable gain amplifier in the MAX2829 Tx path. The X-axes below are path loss, ranging from -60dB (maximum transmit power, 60dB series attenuation) to - 120dB (minimum transmit power, 60dB series attenuation).42 The independent variable in both tests is transmit power at node 0, swept over a range of 60dB.
