    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
