Khozmo 64 Step Relay Based Ladder Attenuators

Our new great design based on HQ Omron relays instead of moving contacts.  Though they look like mechanical switches, they are operated by either the optical encoder, or the remote control.   Khozmo designed their own optical encoder which guarantees long life operation.   Remote control is included.

Ladder type stepped attenuator

This is where 2 resistor and 2 switch contacts are used per step, making up a unique combination of resistors per step that add up to the impedance of the stepped attenuator you use. Effectively a voltage divider network.

The total series resistance of each two resistor set is equal, so the signal source always sees the same impedance.
