Fairchild R70B The R70B RFI Receiver is a portable

The R70B RFI Receiver is a portable calibrated receiver that can be used to measure interference at proposed receiver or computer sites, shielding effectiveness of enclosures, noise radiated from power lines, transmitted field strength and antenna flatness plus numerous other applications. Tracking RF pre-selection in all nine tuning units enhances selectivity. The unit is portable in one lightweight attaché case with a rechargeable battery and has calibrated responses in both narrowband and broadband noise. Frequency range is from 100kHz to 1100MHz and the voltage range is from 1.0 µV to 1.0 V (100kHz to 34MHz) & 1.0 µV to 3 mV (34MHz to 1100MHz). Input impedance is 50-ohms (Type N). Provides outputs of Audio, Final IF, FM and AM Video.
