OK having seen your last post I've repeated the measurements on the switchable probe....
Without being plugged into the scope, and the probe set on ×1 the Atlas measured it as 50pF.
Without being plugged into the scope, and the probe set on ×10 the Atlas measured it as 15pF.
Plugged in and set on ×1 the Atlas measured it as 1000pF
Plugged in and set on ×10 the Atlas measured it as 15pF
Plugged in and set on ×1 the Atlas measured it as 1200pF with a certified 1nf in parallel, (someone throw that penguin a mackerel,
)
Is that calculable, or a pre existing observation?
Ta!
Amie.
