Exact Electronics Model 501 VCF/Sweep Function Generator

Vintage benchtop electronic test instrument manufactured by Exact Electronics, Inc., Tillamook, Oregon, USA. This Model 501 generates selectable electrical waveforms for circuit testing, troubleshooting, and laboratory applications, with adjustable frequency, amplitude, DC offset, and sweep controls. OPERATING CONDITION & REQUIRED CORD REPAIR The unit is operational, but the attached power cord has a split outer jacket near the point where it enters the chassis, exposing the internal insulated wiring. The cord and strain relief require inspection and repair or replacement by a qualified technician before further use. Sold as an operational instrument requiring power-cord repair—not as ready-to-use equipment. Calibration status and accuracy across all settings have not been verified.
