Today’s new high dynamic range power sensors are not built the same as the older generations of sensors. Older generations of power sensors only had a correction table for their frequency response. This was a simple number that could be easily dialed or entered into the power meter allowing the power meter / sensor to make accurate measurements.
A reader noticed the tolerances were not correct. Lower and upper limits in the table of the article have now been corrected–the online version of volume 20:3 has been updated. We apologize for the incorrect calculations and any inconvenience they may have caused.
