Rental Partners - Fast Power Measurements for X-Series Signal Analyzers
Notas de Aplicação
1. Overview of Fast Power Measurements
Fast Power is available for the UXA, PXA, EXA, and MXA Series Signal Analyzers (N9040B, N9041B, N9030B, N9020B, N9021B, and N9010B). By using an FPGA hardware-based FFT engine built on the digital IF, measurement times are significantly decreased and repeatability for a given acquisition time is improved when compared to traditional sweep-based power measurements.
Fast Power is supported by the 40 MHz digitizer (option B40) as well as the wideband digitizers up to 510 MHz bandwidth. For digitizer paths from 10 MHz to 40 MHz, the embedded FFT engine uses RMS power averaging. For digitizer paths greater than 40 MHz, only voltage averaging is available.
