BirdModel 8325
Tenuline 500W--30 dB Attenuator-DC to 500MHz,
New price is 00
This is a heavy duty, 50 Ohm, 30 dB RF attenuator, designed to last a lifetime!
I purchased it for my own use as a consulting engineer.
You have a 14 day right of return unless it is damaged or opened.
It was just Refurbished with a complete disassembly, cleaning, O-ring replacements and a new, precision, non-inductive power resistor.
All parts are new from Bird. Dielectric oil has been filled to correct level.
The specs are:
Input:
50.02 Ohms
;
Output:
49.77 Ohms;
Factory specs for input and output resistance is 50 +/-2 Ohms
;
Input to Output:
93.49 Ohms
, Factory spec is 93.7, +/- 2 Ohms.
All measurements are almost perfect.
Attenuation: 30.15 dB @ 0 to 500 MHz,
Factory spec 30 dB +/- 0.5 dB. See photo: Tracking Generator set at -9 dBm. Analyzer reads -39.15 dBM. Difference is -30.15 dB--Exceeds specs--flat to ~750 MHz
See photos for condition and measurements.
Paper Manual included
