… all the time?
… after some time of use? (After how long time?)
… at special times of the day (or night)? When?
… at all locations in the hospital, or only in one room/area?
… from time to time, no special pattern of time is observed?
7-5-4 Overview of Types of Noise
There are different types of noise. Use the information next to classify the noise and possible cause.
7-5-4-1 Noise Picked Up from the Air
Electromagnetic Interference (EMI) from radio frequencies, magnetic fields, and transients in the air.
If picked up by a probe cable, the noise will be coherent -“penlight noise” pointing down in the picture -
due to the fact that the noise is received on all channels.
Is it a problem on one probe only?
Try another probe.
Is it a problem on one of the probe connectors only?
Move the scanner to another location and verify any changes.
