RF Power Meter Comparison Chart

A key goal of the MB-1 design was to build a meter that was fully configurable in a stand-alone mode without requiring a PC to control any of the meter's functions. Therefore, the charts below compare only those features that are available on all meters when used in a stand-alone mode. 

The other meters in the comparison chart below support various PC features. For additional information on those features, please consult the manufacturers' websites.

The data for the other meters was obtained from the websites and manuals for those products where available. If you see anything that you believe to be incorrect, please bring it to our attention.
