Amplifier Measurement Example
Amplifier Measurement Example
Dual Channel
This example contains information about measuring the residual noise of two-port devices. It
demonstrates a residual phase noise measurement for an RF Amplifier. Refer to the PNTS User’s
Guide Chapter 7 for more information about residual phase noise measurements.
Equipment Needed
— N5511A-K26 Phase Noise Measurement Interface
— DUT (this measurement features CMMIC CMD274P)
— 8 SMA cables (to match
)
— Signal Analyzer (this is only used for setting up the calibration tone)
— Stimulus source
— Calibration source
Connections
Wire the system using the diagram (
) and the PNMI (
) for the front view of the PNMI
connections.
To prevent damage to the test system’s hardware components, verify that the input signal is
within the test system’s power limits. Refer to the N5511A Data Sheet online.
For optimal measurement performance, both channel paths need to be matched in delay. This
means that LO cable lengths need to match each other as well as the RF port cables.
