Making a Network Analyzer Measurement with Power Sensors

Question asked by lynchdavidb on Nov 10, 2011
If you need to make a scalar network analyzer measurement of your device you can doing it at low cost using hardware you already have.  To make a gain measurement and return loss measurement of any device, you can use a scalar network analyzer such as the discontinued Agilent 8757D or you can use power meters and power sensors, along with a signal generator and some other hardware on your bench to make the same measurement. You probubly already have all of this equipment laying about the lab.

To do: this review the Applicartion Note "Scalar Network Analysis with U2000 Series USB Power Sensors" which you can find at:

This note shows you how to put together a system to make these measurements.  There is also free sofware available to make these measurements at:
