Title:
DEVICE AND METHOD FOR MEASURING POWER OF SPECTRUM ANALYZER
Document Type and Number:
Japanese Patent JPH0735789
Kind Code:
A
Abstract:

PURPOSE: To provide a device and method for measuring power which can measure a total power and an average power accurately without any error in measuring noise and spectrum diffusion signal.

CONSTITUTION: In a spectrum analyzer, an input signal is converted to a genuine number of PPn=10Pn/10 by providing a genuine number conversion part 11. Then, by providing an average value calculation part 12, an average value of PPa=(PP1+PP2+...+PPN) is obtained. Then. by providing a logarithmic conversion part 13, an average power is obtained by Pavg=10logPPa, thus constituting a power measuring instrument. Also, by providing a total power calculation part 14 and by multiplying an average power per unit by a measurement frequency value, a device for obtaining the total power may be configured. Also, the operation may be realized as a method for measuring power.
