Wavetek 180

The Wavetek 180 is a versatile sweep/function generator that produces sine, square, triangle, TTL pulse, ramp, and DC waveforms across a broad frequency range. It supports both manual and voltage-controlled frequency adjustment with an internal sweep generator for frequency response analysis and system characterization. The instrument delivers variable amplitude outputs through dual BNC connectors with selectable DC offset capability, making it suitable for testing and calibrating analog and digital circuits across laboratory and industrial environments.
