Typical Results
Typical results of this test are shown in the following screen shot. The filter amplifier used for this
test had a gain of 100 and a bandwidth of 0.5 to 5000 Hz (FA64I-100-0.5-5000). If you use a
filter amplifier with a narrower bandwidth, you can generally expect a slightly lower noise level.
Noise level test with #MPA8I and FA64I-100-0.5-5000 filter amplifier.
The noise level is 60 μV peak to peak with the provided test model probe (channels 1 – 32)
and 20 μV peak to peak with grounded inputs (channels 33 – 64). The top window shows
raw data; the bottom window shows the extracted peak-to-peak amplitudes of channels
1 and 33. (The miniature preamplifier was shielded by a metal case connected to the ground /
earth of the test lab.)
