Why are the 435/6/7/8A/B Power Meter, 53147/8/9A Microwave Counter/Power Meter/DVM, 70100A MMS Power Meter, E1416A VXI Power Meter and the E7495A/B Base Station Test Set incompatible with the N8480 Series Power Sensors (Standard or CFT option)?

The N8480 Series Power Sensors (Standard or CFT option) employ an EEPROM chip, which requires an additional line to power it up (see the N8480 Series Block Diagram below). The 435/6/7/8A/B Power Meter, 53147/8/9A Microwave Counter/Power Meter /DVM, 70100A MMS Power Meter, E1416A VXI Power Meter and the E7495A/B Base Station Test Set do not have the required additional line to power the EEPROM. This is why these instruments are incompatible with the N8480 Series Power Sensors (Standard or CFT option).
