E4446A 44 GHz Spectrum Analyzer, 2.4 mm (m)

The Keysight E4446A PSA measures and monitors complex RF and microwave signals up to 44.0 GHz. Part of Keysight’s high performance PSA spectrum analyzer range, the E4446A Spectrum Analyzer is capable of a frequency range of up to 325 GHz with external mixing. This tenacity in terms of frequency range is coupled with great accuracy standards, a high degree of flexibility, and an analysis bandwidth that starts from the built-in 80 MHz (14-bit digitizer resolution). This can expand all the way to 300 MHz of analysis bandwidth capacity if combined with an oscilloscope applied as an additional digitizer.
The Keysight E4446A is a great device for spectrum analysis that comes loaded with features, such as:
All-digital IF with auto-ranging capability
Phase noise optimization
Full detector suite
160 resolution bandwidth settings (10% steps)
2 dB step attenuator
FFT and swept measurement modes
Gated sweep
Power Suite one-button power measurements
EMI measurements with CISPR compliant bandwidths and detectors
