High Resolution Phase Shifters DC-18.0 GHz Direct Reading  General Specifications Models This series of directly calibrated phase shifters feature a very high degree of accuracy and extremely high resolution for fine tuning of phase. The digital readout is calibrated in 0.01°/GHz increments with an accuracy of ±0.1°. Altho units are calibrated at 1 GHz, use at other frequencies is easily obtained by multiplying phase readout x operating frequency GHz.
