HP / Agilent 70340A Microwave Synthesizer, 1 GHz to 20 GHz

The HP/Agilent 70340A is a modular microwave signal synthesizer engineered for automated test equipment systems within Agilent’s Modular Measurement System (MMS) architecture. Operating from 1 GHz to 20 GHz, it delivers leveled RF output with exceptional spectral purity and supports pulse and analog modulation. Optional frequency extension via the HP 70341A module expands coverage down to 10 MHz, enabling comprehensive signal generation across microwave and lower frequency bands.

– Key Features

The 70340A integrates as a 4-slot module within Agilent's 70000-series test systems. SCPI and HP-IB programming interfaces enable automated control. Optional output step attenuator (1E1) and 3.5 mm RF connector (1E9) expand flexibility. High-fidelity pulse capabilities with sub-10 ns transitions support demanding modulation requirements. Internal leveling with remote port correction ensures consistent output flatness across distributed test configurations.

– Typical Applications

Microwave component characterization, antenna testing, error performance analysis, and modular ATE system integration. The pulse and AM modulation combination simulates dynamic RF environments for realistic device validation.
