Acoustooptic modulators (deflectors) find implementation as high speed spectrum analysers. Change of its construction by add second electrode and analyse of interference picture, give possible measure the phase of signal. They make of possible measure of frequency and direction of propagation signal simultaneously. The main of problems resolved in this implementation is a cross talk signals. In this paper described influence of cross talk factor on measuring errors, possibilities of correction and results of implementation correction procedure. In laboratory set-up the standard errors of measure the phase of signal 3 0 was obtained.
