Pure signal generation for RF testing
The AP500xA compact and portable RF analog signal generators from Keysight, enable you to characterise, and fully stress test your wireless devices. This range enables you to test devices up to 26 GHz quickly and confidently, with exceptional output power range, low phase noise, and fast switching speed.
The AP504xA and AP5042A single and multi-channel vector signal generators provide you with a combination of performance and versatility in a compact form factor. Leverage the excellent phase noise, spectral purity, fast switching speed, phase coherent multi-channel performance and vector modulation capability of these generators for an effective and cost-efficient tool in your lab. Put these sources to work, testing in application areas such as receiver testing, phased array antenna testing, avionics testing, RADAR & EW signal generation, quantum computing testing, MIMO signal generation, production testing and more.
