APPH Phase Noise Analyzer Increasing operating frequencies for radar and communications are pushing the test and measurement industry to provide solutions for characterizing phase noise in these upper bands. The development of test systems at mmWave and higher frequencies is important for research and will become essential for production testing. This article shows a cost-effective and
Multi-channel Signal Sources Electronically generated signal frequencies always have phase noise or frequency jitter. Over time and with varying ambient temperature, the signals will drift further. Generating accurate and stable signal frequencies and, for many applications, maintaining the relative frequency and phase stability among multiple channels are a fundamental and ongoing challenge. If the phase
APVSG: Vector Signal Generator AnaPico of Switzerland has launched its APVSG series of vector signal generators (VSGs), which cover frequency ranges from 10 MHz to 4, 6, 12, 20 or 40 GHz and are available in single– and multichannel versions. Each VSG channel contains built-in arbitrary wave signal generation, RF and microwave signal generation and
APVSG: Vector Signal Generator Today, digital modulation schemes are widely used in communication systems, and the increasing need for data bandwidth has pushed the signal purity and modulation bandwidth requirements for modern vector signal sources. Other applications with similar performance requirements include radio surveillance, interference analysis, radar signal analysis and electronic warfare. Addressing these demanding
APPH40G: Phase Noise Analyzer Phase noise is an important parameter for the performance of a radar system. Most radars employ pulse modulation, and the velocity of the target is derived by detecting the Doppler shift of the radar’s reflected signal relative to the frequency of the transmitter. The transmitter’s own phase noise strongly affects the

APMS40G-ULN-PHS: multi-channel synthesized signal generators Simulating and testing multi-antenna systems such as phased arrays or beamforming antennas requires a test system capable of providing multiple signals with deterministic frequency and amplitude with stable, user-adjustable phase relationship among those signals. AnaPico’s APMS multi-channel signal generators provide a well-designed solution for these applications, packing unique phase coherent
