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.
– Compatibility & Integration
Designed for seamless operation within HP/Agilent Modular Measurement System mainframes and 70000-series platforms. Direct pairing with the HP 70341A frequency extension module. Compatible with instruments including the HP 71500A microwave transition analyzer and HP 71600 Series error performance analyzers.
