Fukuda got a reaction from WalterC in How to change input impedance settings for analog input on DAQami
When measuring voltage with analog input ACH0 and ACH1 using USB-2627 and DAQami, the measured voltage will not match the actual voltage.
Is it possible to change the input impedance of analog input on DAQami?
If possible, could you please tell me the command? Or can I do that using UL and InstaCal?
I think this phenomenon is caused by installing voltage dividing resistors of 300kΩ and 100kΩ to reduce the voltage to a quarter before inputting it. By inputting 1V into this, I can see the following:
Voltage at the connector end of the channel containing the voltage dividing resistor: Measured about 0.7V Measure voltage of channel without voltage dividing resistor: 1V From this phenomenon, I inferred that the input impedance of the analog input port was low.

Fukuda reacted to Fausto in CAD file for USB-1208HS-4AO and USB-1608HS-2AO
Hello @Fukuda.
A 2D drawing of the USB-1208HS-4AO is available, but no drawings for the USB-1608HS-2AO.

Fukuda reacted to JRys in How to collect analog input data every trigger edge detection for USB-231
The External Trigger input is used to signal the start of data collection. What you need is a device that has an external clock input like the USB-1608G.

Fukuda reacted to Fausto in Regarding the EOL schedule for PCI-DDA08/12
Hello @Fukuda.
The PCI-DDA08/12 (SKU: 6069-410-088) is not scheduled for EOL. The "not recommended for new applications" note was posted because the product is an older form factor (PCI). We suggest that new applications consider the USB-3100 Series instead.
