I need to measure the power or power spectral density of some zigbee

Any pointers were to understand power measurements with spreadspectrum would
be appreciated.

Several people - Boonton, Agilent, Keithley maybe - make fast-response
wideband RF power meters, suitable for RF burst measurement. Big
bucks, mostly.

And these are cute:

A simple diode detector, from Mini-Circuits or whatever, might get you
into the rough ballpark, but calibration and matching become issues.

PSD for pulsed RF is a more serious issue.
