Set the Pull-up/Pull-down resistor

Are there pull-up/pull-down resistors on the measurement line?
Or can I set a specific pull-up/pull-down resistor’s value?

The Saleae Logic Pro 16 page says that the input impedance is 1M or 2M Ohm, depending on model. Usually that’s to ground.

I have never heard that it’s possible to adjust the input impedance. What are you trying to achieve?

@ukjaeyu For quick reference, our datasheets can be found below:

The input impedance rating for the inputs (found in the datasheets above) are to ground.
