Abstract: Technologies directed to calibration and measurement of transmit phased array antennas with digital beamforming are described. One method includes a communication device generating a radio frequency (RF) signal and a reference RF signal generated using a first offset value. A processing device sending to a measurement device data indicating a first periodicity of the first RF signal and a first data acquisition parameter. The processing device receives measurement data indicating conditions of the first RF signal and the reference RF signal received at the measurement device. The processing device determines signal characteristics of the first RF signal and the reference RF signal. The processing device sends a command to the communication device. The command indicates a modification of the first offset value to a second offset value. The communication device generates a second RF signal using the second offset value.
