Agilent Technologies N1911A - Figure 11-159 P-Series Sensor Error in Peak-To-Average Measurements for a Two-Tone Input

11 Specifications and Characteristics
268 N1911A/1912A P-Series Power Meters User’s Guide
Characteristic Peak Flatness
The peak flatness is the flatness of a peak- to- average ratio measurement
for various tone- separations for an equal magnitude two- tone RF input.
Figure 11- 159 refers to the relative error in peak- to- average ratio
measurements as the tone separation is varied. The measurements were
performed at –10 dBm with power sensors with 1.5 m cable lengths.
