Patent ID: 8537942

Claim:
A method for correcting for DC offset in a data packet signal received by a data packet signal receiver, comprising: receiving, from a device under test (DUT), a packet data signal with the data packet signal receiver having a plurality of operating environment parameters including one or more of signal frequency, signal gain and operating temperature; if compensation data corresponding to said plurality of operating environment parameters is available, then compensating, within said data packet signal receiver, said received packet data signal with said compensation data, and measuring a DC signal voltage during a gap between adjacent data packets in said received packet data signal to provide a measured DC voltage signal; and if said compensation data corresponding to said plurality of operating environment parameters is not available, then calibrating said data packet signal receiver to provide said compensation data, compensating said received packet data signal with said compensation data, and measuring a DC signal voltage during a gap between adjacent data packets in said received packet data signal to provide a measured DC voltage signal.
