The Multi-Function fixture offers the ability to route mulitple RF and DC channels into one device. Hence, MMICs and other module-like devices that require more than just two power supplies may be tested. The fixture shown here also routes two sets of RF inputs and outputs to the device. When married with the proper RF Control Unit (RFU) configuration, mult-band devices may be stimulated. Further, the pulsed controls may be used to force cycling between bands to test switching performance.
