A secretary in an office above a Bruker AMX-500 is complaining that she has
bought 3 different cordless phones and none of them work in her
office. The last one is a Panasonic KX-TG5240 5.8 GigaHertz model. I told
her it "might be possible" that rapid pulsing experiments (wide-line solid
state) could cause RF interference for her phone. Maybe the sharp edges of
pulses have RF harmonics with high enough frequencies to interfere. I've
always worried about problems the other way around: cordless phones and
cell phones broadcasting into the NMR receiver. But I often see
researchers nowadays talking on their cell phones while sitting at the NMR
console, and I've never seen any obvious glitches as a result.
Does anyone have any real scientific information, or believable
anecdotal information, about NMR instruments interfering with cordless phones?
