Keysight Self-Configured System Installation Guide 2-21System DescriptionCompatible Millimeter-wave ModulesCompatible Millimeter-wave ModulesNon-LFE broadband systems use the N5293A and N5295A (TxRx) millimetermodules. For banded millimeter-wave system measurements, theTransmission (Tx) and Reflection (Rx) banded millimeter modulesmanufactured by Olsen Microwave Labs (OML) and Virginia Diodes Inc (VDI)can be used with the N52xxB banded mm-wave network analyzer systems.Both types of systems require the N5292A controller. Refer to Table 2-10 onpage 2-22 and Table 2-11 on page 2-23.Keysight’s N5293A/5A, and OML’s and VDI’s Transmission/Reflectionmillimeter-wave modules contain an RF source multiplier, dual directionalcoupler, reference downconverter and a test downconverter. A singleTransmission/Reflection module allows the measurement of reflectioncoefficient only (e.g., S11, S22, etcetera). Refer to Figure 2-10 on page 22.OML/VDI’s “Receive only” millimeter-wave modules contain a testdownconverter to receive the test signal from a Transmission/Reflectionmillimeter-wave module. The use of a Receiver module, as the second module,allows the system capability to measure a single transmission coefficient only(e.g., S21, S12, etcetera). Refer to Figure 2-10 on page 22.The use of two Keysight N5293A/95A or OML/VDI Transmission/Reflectionmodules in the millimeter-wave VNA system allows for all four S-parameters tobe measured. The test downconverters of Transmission/Reflection modules arethe receivers for the signal from the modules sources. When the two moduleswaveguide are connected, S11 and S21 are measured in the forward direction,S22 and S12 are measured when the signal path is reversed. If a 4-Port systemis configured with Transmission/Reflection modules, all 16 S-parametermeasurements can be made on a 4-Port device. Refer to Figure 2-10 onpage 22."Receive only" millimeter-wave modules only apply to the OML/VDImodules.
