Khozmo Ladder Attenuators

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 with ladder attenuators. 

Switching type: MBB (Make Before Break) 
Number of steps: 48
Attenuation range: -60 dB … 0 dB
Attenuation per step: steps 1 to 11 – 2dB, 12 to 48 – 1dB
Contact material: Hard gold 
Polished wiper and contact pins
Extremely short signal path
Channel matching: +/-0.1 dB
Resistance: 5K, 10K, 25K, 50K, 100K, 250 kohm
Mechanical life: > 50 000 cycles
CNC machined PA11 aluminium body
Precision ball bearing support
Shaft diameter: 6 mm
Indexing angle: 7,2 deg

Note:  when ordering, please let me know what impedance you need.  Options 10K or 100K.   The price is the same.  I cannot tell you which one you need.  That is up to the design of the piece of equipment.  You are safe if you swap the same value impedance.
