Is it possible to measure DC current in Nano Ampere range?
Is it possible to measure DC current in Nano Ampere range?
Is it possible to measure DC current in Nano Ampere range by using Second-Generation PC USB Oscilloscopes like VT DSO-2A20E? If so what will be the min/max resolution limit? Thanks

Re: Is it possible to measure DC current in Nano Ampere rang
The second generation VT DSOs such as 2A10, 2A20, 2A10E, 2A20E have a resolution of 10~16bits. As the sampling rate goes down, the resolution goes up. The minimum full-scale voltage range is +/-10mV. To measure a current, a resistor has to be used to convert the current to a voltage. For example, you can use a 10k resistor to convert a 1000nA to 10mV. This is of course provided that the inclusion of the 10k in-series resistor will not change the circuit under test too much.
