The TF2300B FM/AM Modulation Meter measures FM deviation in ranges from 1.5kHz to 500kHz full scale at modulation frequencies between 30Hz and 3.4kHz on the 1.5kHz range, and 30Hz and 200kHz on all other deviation ranges. AM depth can be measured up to 95% in a 30Hz to 50kHz modulation bandwidth. Either FM or AM can be measured in the presence of the other. Carrier Frequency range: 4 to 1200MHz (FM); 4 to 400MHz (AM). Calibration Accuracy: ?3%. 50-ohm input impedance.
