ADLINK PXIe-9908 8-channel four quadrant high-density source measurement unit

Product Overview and Core Features

Channel and output mode

Normal mode: 8 independent SMU channels; Output voltage range -10V~+20V; The maximum power for a single channel is 2W, and the total power for the entire machine’s 8 channels is 16W.

Cascade cascade mode: channels are merged into 4 high-performance channels in pairs; The output voltage is expanded to ± 30V; the maximum for a single channel is 3W, and the maximum for a total of 4 channels is 12W.

Current range: 9-level range: 100 mA, 10 mA, 2 mA, 200 μ A, 40 μ A, 5 μ A, 1 μ A, 100 nA; 10 μ A range only supports measurement and cannot source.

High voltage measurement capability: With a range of 10 μ A, it can measure ± 100V voltage (only for measurement, not for source), enabled by hardware pin En_100V.

performance metrics

Resolution: 18 bit;

Single channel maximum measurement sampling rate: 1 MS/s;

Maximum source output update rate: 100kHz;

Source event delay: 5 μ s.

Hardware function: 4-wire remote detection for each channel (Sense HI/LO); Guard shields the driver output, reduces leakage current, and improves the accuracy of weak current measurement; Support sequence engine, with input trigger and output trigger.

Front panel interface: CN1, 62 pin D-Sub female socket, integrated with all 8-channel Output HI/LO, Sense HI/LO, Guard, 100V enable, external calibration pins.

Cable reminder: Standard cables TB-6221 and ACL-10262 may cause unstable output and measurement at low current levels below 2   mA; Specialized cables and adapter plates must be customized for weak current applications.

Typical Applications

ATE automatic testing system, Mini/Micro LED wafer probe testing, IC testing, laboratory automation, industrial process monitoring.

Key electrical specifications

Specification conditions: Environment 25 ± 5 ℃; Preheat for 30 minutes; Calibration cycle of 1 year; The maximum speed of the chassis fan.
