BK Precision 4012A Sweep Function Generator

The BK Precision 4012A Sweep Function Generator is a compact bench instrument delivering accurate waveform output up to 5 MHz, with sine, square, triangle, pulse, and ramp modes across a frequency range of 0.5 Hz to 5 MHz. Coarse and fine frequency adjustment lets you dial in exact values, while a 4‑digit LED display provides clear readouts of frequency and settings. It supports linear and logarithmic sweeps with sweep rates from 0.5 seconds to 30 seconds, and includes a variable duty cycle along with an adjustable DC offset to tailor signals for amplifiers and signal‑path testing. Powered from 115/230 VAC, 50/60 Hz, the unit uses an internal jumper to select the line voltage and features a dedicated BNC output connector with an included cable (BNC to alligator clips) and an instruction manual. Its enclosure measures about 10.5" W × 4.5" H × 12.25" D and weighs roughly 4 lb (1.8 kg), making it suitable for electronics labs, classrooms, and desk setups for bench testing, signal integrity checks, and general waveform generation needs.
