Agilent E4440A PSA Spectrum Analyzer Review

Agilent E4440A PSA Spectrum Analyzer Review

Known industry wide as for its superb accuracy and speed, the Agilent E4440A is a powerful spectrum analyzer that is optimized for carrying out measurements in the 3 Hz to 26.5 GHz range. This truly powerful test solution is designed to offer an absolute amplitude accuracy of +/-0.19 dB and also an excellent average noise level of -155 dBm.


The E4440A spectrum analyzer provides operators with an analysis bandwidth of 10 MHz in the basic mode. The technician is able to measure and capture complex signals by employing the optional 40 MHz or 80 MHz. These options are suitable for applications that require an analysis bandwidth that is not achievable in the basic mode. The spectrum analyzer also offers a third order intermodulation of -78 dB for 80 MHz or 40 MHz analysis bandwidth. It is specifically optimized for carrying out calibrated VSA measurements and features  up to 300-MHz analysis bandwidth for such measurements.
