10 | ni.com | NI PXIe-5694 Calibration ProcedureConfiguring the HardwareComplete this process to connect the two sources to a power sensor and power meter, preparingthe configuration for verification and characterization. This assembly is used in VerifyingThird-Order Intercept Point Out-of-Band.1. Connect the spectrum analyzer REF OUT connector to the REF IN connector on the backof the PXI Express chassis. Use a standard BNC (m)-to-BNC (m) cable.2. Connect one 10 dB attenuator to a non-common low-frequency combiner connector. Labelboth the low-frequency combiner connector and the attenuator P1.3. Connect the remaining 10 dB attenuator to the remaining non-common low-frequencycombiner connector. Label both the low-frequency combiner connector and the attenuatorP2.4. Use an SMA (m)-to-SMA (m) cable to connect RF source 1 to the 10 dB attenuator labeledP1. Label the signal generator Source 1. Label the cable S1P.5. Use an SMA (m)-to-SMA (m) cable to connect RF source 2 to the 10 dB attenuator labeledP2. Label the signal generator Source 2. Label the cable S2P.6. Connect the combiner common connector to power sensor A.7. Connect channel A of the power meter to power sensor A.Figure 1.
