Note 7 Uses the 1/3 octave bandpass filter to enhance the measured range in the presence
of wideband noise. Alternate (interfering) channel input must be ≥5 mV.
Note 8 For fully specified performance. Usable with inputs as low as 10 mV. Readings are
disabled for in[uts below approximately 7 - 8 mV.
Note 9 System specification including contribution from generator.
