Calibration Parameters
Each submodule has a serial e²prom memory (or similar) where:
The device type is encoded
The biasing parameters are stored (that ensures that single modules may be
added/changed
Tip
At cut-off frequencies <1000 Hz, reflected frequencies above 50x the corner frequency
are possible.
Example 1: f
c
= 100 Hz
Reflected frequency band starts at 50 Hz x 100 Hz = 5000 Hz. A signal frequency of
5100 Hz would be noticeable at 100 Hz.
Example 2: f
c
= 1000 Hz
Reflected frequency band starts at 50 Hz x 1000 Hz = 50,000 Hz. A signal frequency of
51,000 Hz would be dampened 6 dB by the static low-pass filter. This signal would be
noticeable for signal strengths above 20 dB.
If you need a device for low-frequency applications, iba AG can supply a variant of this
device for sampling at 1 kHz or less, with a static low-pass filter. Please contact iba AG
for further details.
