HP / Agilent 3310B FUNCTION GENERATOR

The HP/Agilent 3310B Function Generator delivers precision waveform synthesis across seven distinct output types: sine, square, triangle, positive pulse, negative pulse, positive ramp, and negative ramp. Operating from 0.0005 Hz to 5 MHz across ten decade ranges, it combines broad frequency coverage with exceptional output control - delivering up to 30 V peak-to-peak (open circuit) or 15 V peak-to-peak (into 50 Ω) on the high output, with minimum outputs below 30 mV peak-to-peak. The instrument features adjustable DC offset (±10 V open circuit, ±5 V into 50 Ω), a built-in attenuator providing >30 dB control, and external VCO capability for frequency modulation and external triggering. Pulse and ramp functions offer fixed 15% or 85% duty cycle operation.
