Step attenuators are used in RF test equipment, signal conditioning, telecommunications systems, and laboratory measurements to reduce signal levels in controlled increments. Commonly found in telecom bench setups and RF/microwave test configurations requiring manual attenuation adjustment.
Condition: Used
This Texscan RA-70 Adjustable Step RF Attenuator has been inspected and tested at our facility and is in working condition. We measured the resistance across the center pins at each dial position using a multimeter. The approximate readings at dial settings 0 through 10, plus the Zo position, are as follows: 0.4, 8.9, 17.3, 25.8, 33.9, 42.4, 50.4, 57.3, 64.7, 71.4, 77.7, and 149.4 ohms. The SMA connectors show visible oxidation and surface wear consistent with age and use. The aluminum body and dial are intact. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
