The average mode of the X-Series peak and average power sensor provide accurate average
power measurements for broadband modulated signals similar to a thermocouple sensor. This
is due to the X-Series power sensor’ four path diode design, which enables all the diodes to
operate in their square-law region.
1. Specification is based on pulse signal with ≥ 80 ns rise time.
2. Specification is based on pulse signal with 5 ns rise time.

Characteristic peak flatness
The peak flatness is the flatness of a peak-to-average ratio measurement for various tone
separations of an equal two-tone RF input. Figure 5 below refers to the relative error in
peak-to-average ratio measurements as the tone separation is varied. The measurements were
performed at –10 dBm and applicable for carrier frequency ≥ 300 MHz.
