Specifications

• Each decade consists of inductors wound around a ferrite pot core,
which gives a Q factor between 55 and 100.
• Like all inductors of this type, the applied voltage mostly depends on the
operating frequency. The voltage must be limited to avoid core saturation
and overheating.
• Robust switches with metal frame and gold-plated contacts.
• Output of each decade on safety socket.
• Screen outputs (front panel and case) on safety earth socket.
