F Understanding the Bias Networks
Features
Using the Agilent 11612V K11 and K21 bias networks, you can
simultaneously supply DC bias and RF energy to the device under test
(without the need to use patch cables or adapters) to make convenient
and accurate DC and S- parameter measurements.
Each bias network provides:
• floating triaxial FORCE connection to input current or voltage
• floating triaxial SENSE connection to monitor voltage or current
• floating triaxial GNDU connection to implement an active ground
• 2.4 mm coaxial RF input
• 2.4 mm coaxial combined RF/DC output
• device bias oscillation suppression
