Thank you! I'm sorry, I think I explained it wrong. Connectd is V+ is ch1+ v- is ch2+ ch1-, ch2- gnd The resistance I want to measure is 1 kohm, so 1 kohm should come out when measuring impedance. However, the impedance measurement in two ways did not produce 1 kohm. Can you tell me what the problem is?

Hi! I'm going to measure impedance with AD2. I used W1-C1-DUT-C2-R-GND. I don't know is when measuring the circuit like below, I don't know if I should connect the reference resistor to GND or scope2(V-). Which of the 2 methods is correct?

Thank you! So, what is the plug size of the secondary power supply?

Hi! I'm using analog discovery2. I know that the maximum output current for analog discovery 2 is 700 mA. I have to use a current of about 450mA. However, the analog discovery 2 basically uses 300mA to 320mA. So it can only use a current of 350 mA. Is there a way to reduce the basic current or increase the output current?

Thank you so much!! !!

The sample rate is the same and the noise in the gui is removed, but it comes out differently. Shouldn't GUI and python sample code come out the same?

Hi! I'm measuring the voltage value in my circuit. But, The GUI scope value finely differs from the python sample code. I use the 'AnalogIn_Record.py' code for Python example. Can you tell me why it's different? Help..me..please...

Hi! I found lock-in system in waveforms. But I want to use Python to use a locking system. I looked for SDK manual but couldn't find directions for use lock-in system . How can I use Lock-in system through Python?(AD2) Help me please...
