600 Ohm Precision Step Attenuator
RLC Electronics’ AT-600 Series precision step attenuators are designed to provide an extremely accurate attenuation over the range of DC-1 MHz. Selected precision chip resistors and surface mount construction provide accuracy, long life and repeatability. Units are provided with knobs and are calibrated for nominal attenuation steps.

To designate the attenuator desired use:
1: 600 for a 2 section, 0-50dB attenuation in 1dB steps 601 for a 2 section, 0-90dB attenuation in 10dB steps 602 for a 3 section, 0-100dB attenuation in 1dB steps |
2: B for BNC female connectors P for binding posts |
Example: AT-602-B is a 0-100dB attenuator with BNC female connectors
