Thankyou for your inquiry with regard your 2104 and associated attenuation inquiry.
PicoScope has a built-in library of common probe types, such as the x1 and x10 voltage probes used with most oscilloscopes, but if your probe is not included in this list you can use the Custom Probes dialog to define a new one. Custom probes can have any voltage range within the capabilities of the oscilloscope, display in any units, and have either linear or nonlinear characteristics.
Custom probe definitions are particularly useful when you wish to display the probe's output in units other than volts, or to apply linear or nonlinear corrections to the data. Click Tools on the Menu bar and select custom probes.
One option available would be to use the 20:1 attenuator . http://www.picoauto.com/attenuator.html
You could also use a standard 10:1 probe.
