Condition: For parts or not working

This Keysight Agilent 85514A 4-in-1 OSLT mechanical calibration kit is listed as out of specification and is strictly sold for parts or repair purposes. No returns are accepted.

What is typically included:
• 85514A 4-in-1 OSLT calibration module (open, short, load, through combined unit)

The Keysight (formerly Agilent) 85514A is a 4-in-1 OSLT mechanical calibration kit designed to calibrate vector network analysers and other RF test instruments via a Type-N male (m) 50 Ω interface. It integrates four calibration standards — open, short, load, and through — into a single compact, lightweight module, simplifying the calibration workflow and reducing the number of connections required.

The built-in through standard enables straightforward calibration of non-insertable devices, such as cables or filters fitted with male-male Type-N connectors, making it particularly useful in field and lab environments. The kit is compatible with Keysight and Agilent VNA platforms including the PNA, ENA, and FieldFox handheld analyser series, as well as earlier HP and Agilent network analyser families.
