USB-190116-bit USB DAQ module powered from the bus
- Manufacturer
USB-1901 is a multifunction data acquisition module with a USB link, meant for bench and field measurements where no slot is available in the PC.
The high-impedance input, above 1 GΩ, limits the load on the circuit under test and coupling is DC. Acquisition can be started from software, from an external digital trigger or from an analog trigger taken from the signal, and the module works between 0 and 55 °C.
