General description of the
used AGILENT U2722A
for sale.
The Agilent U2722A USB Modular Source Measure Unit is a 3-channel 20V/120mA that can operate in a 4-quadrant operation. The channels could be connected in series or in parallel to achieve up to 60 V/360 mA. It uses the common non-proprietary standard high-speed USB 2.0 interface that provides ease of connectivity - allowing users to set up and configure their tests swiftly with its plug and play feature. The U2722A can function as a standalone module. It can also be used as a modular device, allowing expansion and compact solution when used with the other modules in the USB Modular Instruments and DAQ family. Specifications. Number of outputs: 3. Voltage Output: –20 V to 20 V. Current Output: –120 mA to 120 mA. Voltage programming Ranges: ±2 V, ±20 V. Voltage programming Max Resolution: 0.1 mV. Current programming Ranges: ±1 µA, ±10 µA, ±100 µA, ±1 mA, ±10 mA, ±120 mA. Current programming Max Resolution: 100 pA. Voltage readback Ranges: ±2 V, ±20 V. Voltage readback Max Resolution: 0.1 mV. Current readback Ranges: ±1 µA, ±10 µA, ±100 µA, ±1 mA, ±10 mA, ±120 mA. Current readback Max Resolution: 100 pA. Remote sense operating range: Ensure that the maximum voltage between the OUTPUT+ and SENSE+, OUTPUT–, and SENSE– does not exceed 3 V. Temperature coefficient: Maximum change in output/readback per °C after a 30-minute warm-up is 0.15. Guard output resistance: 0.2 kohm. Noise 10 Hz to 20 MHz (peak-peak): 100 mV typical into a resistive load (floating mode). Output voltage overshoot, ±(% of output + offset): During turn-on or turn-off, the output plus overshoot < 0.1% + 10 mV. Programming language: SCPI (Standard Commands for Programmable Instruments). Maximum sense lead resistance: 1 M-ohm for rated accuracy.
