FROM EDN EUROPE: Spectrum analysis at 42.98 GHz

by Graham Prophet -- EDN Europe, 10/13/2005

Agilent has extended the coverage of its PSA series of spectrum analysers with the E4447A model that now reaches to 42.98 GHz. The company expects the extended performance to be used by developers of 3G cellular and other wireless and digital radio systems, as well as by microwave and millimeter-wave engineers. The instrument offers ±0.62 dB (±0.17 dB typical) amplitude accuracy at 1 GHz; fast measurement of adjacent channel power, with low-level spur search across the whole frequency span. A 2-dB step attenuator covers the range up to 42.98 GHz. The PSA also performs conducted and radiated CISPR and MIL-STD EMI measurements. A Power Suite tool set offers 10, one-button RF and microwave power measurements, including multi-carrier ACP, CCDF and TOI. Fifteen optional measurement personalities perform complex measurements such as phase noise for oscillators, the noise figure of an amplifier, scalar network analysis for components, as well as digital modulation analysis on 2G to 3.5G signals.

Users can combine the PSA hardware with the 89601A VSA software, to add I/Q analysis up to 8 MHz, analogue and digital demodulators, and time, frequency and modulation analysis tools, with standard-signal presets that include GSM (EDGE), cdma2000, WCDMA, and 1×EV-DO.
