Multi-Line Phase Shifters DC-2.0 GHz  General Specifications Models These models utilize a multiline "open trough" design in which only the center conductor's length is varied to achieve phase change. This design combines high reliability with small package size and long delay adjustments. An optional digital readout is available, calibrated directly for degrees at 1 GHz. Readings at other frequencies are obtained by multiplying phase readout by frequencies in GHz. Resolution is 0.1° and accuracy is ±0.5°/GHz on Model 3448B and ±1.5°/GHz for Model 2448A.
