I just connected the analog output from our F71 to an oscilloscope for the first time. Up to now I have only used the front display readings which seem very reasonable. However, the oscilloscope shows weird 100 microsecond period pulses of amplitude +/-15 V, see attached image.
The probe is a FP-2X-250-TF15-15 and is situated in an ambient background field.

I think you probably have the analog output set to show the raw signal, which is really only good for troubleshooting when measuring DC. You could try changing the analog output mode in your teslameter settings to see an output level that has been demodulated and is more representative of the field being measured.
