Page 9: Introduction
Introduction This startup guide describes the procedure for making quick check on 87300B, C, D, 87301B, C, D, E directional couplers and 87310B hybrid coupler.Throughout this quick check procedure, each connection made must be accomplished by following the Principles of Microwave Connector Care. Select the correct microwave cables and adapters when preparing the test setup. -

Keysight 87310B Hybrid Coupler 1 Select the correct microwave cables and adapters when preparing the test setup. 2 Calibrate the network analyzer with full 2-port calibration with setup based on network analyzer model being used. The test setup is shown in Figure Figure 4 Equipment setup using network analyzer with hybrid coupler... - Page 14 Figure 5 Equipment setup using network analyzer with hybrid coupler port 1 and port 3 7 Measure amplitude imbalance (S31/ S21) The following example (Figure 6), of the maximum deviation from 0.0 dB reference is approximately -0.7 dB at 1 GHz. The allowable maximum imbalance is 1.0 dB So the measured amplitude imbalance value -0.7 dB is within the specification.
- Page 15 Figure 6 Amplitude imbalance 8 With the same setup as above, change the format to phase and measure the phase imbalance (S31/S21) 9 Connect the DUT as shown in Figure 7. Measure and record isolation S41 and S44 SWR. [1] Phase imbalance is defined as the difference between phases of port 3 to port 2 within the frequency band.
