FAQ: What is the difference between 20 us and 40 us measurement resolution described in the User’s Guide?

It is assumed that you are referring to the following table on page 163 of the N6705B User’s Guide and page 80 of the N6700 User's Guide:

Current measurement speed is dependent on the number of channels being used in a mainframe and the type of module being used. A parameter refers to either voltage or current when using digitizing mode. When using datalogging or elogging mode, voltage, current, or power count as a parameter.

For example on an N6781A power module, when only one parameter is selected the “digitized current measurement” time interval is 5.12us, for ONE module output. If you had FOUR modules and want to measure current on all four outputs, the time interval would be 20.48us.

The 20us resolution mode, simply allows you to have 20.48us interval resolution for an incremental value. For example if the resolution is set to 40us, and you want to increment your time interval from 20.48us to the next allowable value, the next allowable value would be 60.48us. (20.48 + 40)
