Bruel & Kjaer Type 4420 Statistical Distribution Analyzer - Collector’s Grade

TECHNICAL CONDITION:

Internal Pulse Generator: Fully functional. The unit responds perfectly to the "Period Selector" (0.1 to 10 seconds), and the internal pulses drive the counters smoothly.

Mechanical Counters: All counters (main and channel) flip cleanly and respond to the mechanical reset.

External Inputs: Please note – due to a lack of specific multi-pin cables, the external inputs have NOT been tested.

Lights & Indicators: The red Pulse lamp is fully operational.

IMPORTANT: A power cable is NOT included. The unit was tested using a custom-made connector to ensure internal functionality.

VISUAL & INTERNAL CONDITION:

Pristine Interior: This unit features original silver-plated PCB tracks in factory-new condition. No corrosion, no humidity damage, and all original solder joints. It has been stored in ideal conditions.

Exterior: Excellent vintage condition. The front panel is clean with clear, legible markings. A true masterpiece of Danish engineering.
