Signal Interference

Due to the small voltage signals from the detector, care should be taken to provide appropriate grounding for the

sensor and cable shield wire, in order to minimize the influence of electromagnetic interference (EMI). In instances

where SI-100 series radiometers are being used in close proximity to communications (near an antenna or antenna

wiring), it may be necessary to alternate the data recording and data transmitting functions (i.e., measurements

should not be made when data are being transmitted wirelessly). If EMI is suspected, place a tinfoil cap over the

front of the sensor and monitor the signal voltage from the detector. The signal voltage should remain stable at (or

very near) zero.
