Abstract RU 2673781 C1

FIELD: measuring equipment.

SUBSTANCE: invention relates to a radio measuring technique and can be used in the calibration of meters of complex transfer coefficients of microwave devices with frequency conversion. Calibration method of a two-channel superheterodyne receiver in the meter of complex transmission and reflection coefficients of microwave devices with frequency conversion involves measuring the difference ΔϕOK between the phase angle of the reference microwave device with frequency conversion and the phase of the coherent reference signal from the reference signal generator and the measurement of the difference ΔϕIR between the phase angle of the microwave device under study with frequency conversion and the phase of the coherent reference signal from the reference signal generator. It is proposed to attach a reference microwave device with frequency conversion in the measuring channel of a two-channel superheterodyne receiver and measure the phase difference ϕT between the intermediate frequency signal received from the reference microwave device with frequency conversion in the measuring channel, and the reference signal received from the reference signal generator, then connect the reference microwave device with frequency conversion to the reference channel of a two-channel superheterodyne receiver and measure the phase difference ΔϕOK between the intermediate frequency signal, received from the reference microwave device with frequency conversion in the reference channel, and the reference signal received from the reference signal generator, then calculate the calibration parameter ΔϕCT-ΔϕOK. Further, having attached the studied microwave device with frequency conversion to the measuring channel of a two-channel superheterodyne receiver, measure difference ΔϕIR between the phase angle of the investigated microwave device with frequency conversion and the phase of the coherent reference signal, which is obtained from the generator of the reference signals. Then the difference is finally calculated Δϕ=ΔϕIR-ΔϕK-ΔϕOK between the phase angle of the investigated microwave device with frequency conversion and the reference microwave device with frequency conversion.

EFFECT: technical result is to increase the measurement accuracy, simplify the measurement process, reduce the number of operations required for calibration.
