General Description
N-TM 224a 2CH Variable Attenuator has two block of attenuator which is able to adjust the signal from 0db to 31db (1db/step).Tthe attenuation rate is selected to match slide switches of 1dB,2dB,4dB,8dB and 16dB. The in/output impedance are 50Ω both. Also, the input signal does not have polarity, MAX power is 1/8W.
