Patent ID: 7386070

Claim:
A tester module used to perform an adjacent channel leakage ratio measurement, the tester module comprising: a translation block that translates a received intermediate frequency signal to a baseband signal; a first filter that compensated amplitude and phase of the baseband signal for any unflatness in a host hardware used to capture the received intermediate frequency signal; a re-sampler that decimates the compensated baseband signal; a memory that stores the decimated compensated baseband signal; a router that reroutes the stored decimated compensated baseband signal to the re-sampler, the re-sampler resampling the rerouted stored decimated compensated baseband signal to perform spectrum shifting; a second filter that performs a low pass filtering operation on the resampled rerouted stored decimated compensated baseband signal; and a power detector that detects a channel power of the filtered resampled rerouted stored decimated compensated baseband signal.
