Typical Applications
SMUs are ideal for I-V characteristics and high precision measurements for a wide range of applications, such as semiconductor testing, optoelectronic device testing, active/passive component testing, and material characterization. The IT2800 series SMU combines ATE integration with desktop usage requirements. It is an excellent product to meet the diverse testing needs from R&D to production testing and automated manufacturing, from industrial development to university research.

Six in one high precision SMU, reduce your test cost
Performing IV measurements with conventional instruments such as voltage/current sources, pulse generator, high precision voltage/current meters, etc. is complicated and costly. It takes up limited test bench space and requires engineers control and synchronize programming of multiple devices to perform an accurate measurement. The IT2800 series SMU provides engineers with an economical and efficient solution. It integrates different source and measurement capabilities into one compact form factor of 1/2 2U size, which can accurately source and measure voltage and current. It combine the capabilities of six devices including: 6 ½ digital multimeter (VIR measurement), battery simulator and pulse Generator.

Intuitive graphical display, fast access to product features
The IT2800's front panel has many features that improve the speed of interactive use, user friendliness and ease of operation. These include a 5 inch color LCD display, a USB2.0 memory I/O port, a rotating navigation button, a trigger button, function keys and popular banana jack. The USB2.0 memory port supports easy data storing, test configuration file import and system upgrade. The IT2800 Series supports both graphical and numerical test results view modes. The intuitive graph view, scope view and record view greatly improves the productivity of bench-top tests and IV characteristic analysis.

Graph view: Graph View displays measurement results on XY graphs (such as I-V and V-t curves) on up to 2 channels. This is useful for quick evaluation of device characteristics, especially those obtained from sweep measurements.

Scope view: Scope view draws I-t or V-t curves in real time during the test. It can capture and export up to 600,000 data points. This function is independent of other functions and can be run simultaneously. In Scope view mode, the sampling rate is up to 100,000 points per second (10us), which facilitates the tester to monitor low frequency transient signals.

Record view: Record view allows the user to view historical waveforms and table data over a period of time. The minimum sampling time interval is 100mks, and up to 1 million points of data can be recorded. It also supports exporting to spreadsheets (.csv) for further analysis, greatly improving the efficiency of testing and debugging.

Standard and LIST sweep capabilities
IT2800 Series features standard and LIST sweep capabilities. Under standard sweep mode, it supports parameters such as linear and logarithmic modes, single and double sweep functions and constant and pulsed sweep operation. List sweep functions can efficiently perform arbitrary waveform output which is useful when characterizing devices where the test response varies greatly depending upon the applied voltage or current. The user can use Excel import or panel edit to generate sweep curves of any shape with up to 99,999 data points can be import, which is an ideal choice for testing U-I and I-U features.

Limit test, improve the efficiency of batch product sorting
Limit test is to make pass or fail judgment on measurement data or mathematical operation result data, which are obtained by the channel. A maximum of 12 limits (LIMIT1 to LIMIT12) can be defined. Each limit test status corresponds to 12 Digital I/O ports. When the test passes or fails, the corresponding Digital IO will output pulse signals to implement sorting or grading of products in the production line.

4-wire ohmic measurement permits accurate low resistance measurement
When measuring small resistances the innate cable resistance can create serious measurement error. To solve this, the IT2800 Series supports a 4-wire measurement function. In the 4-wire scheme two of the connectors force current and the other two connectors measure voltage. Since the connectors measuring voltage do not have any current flowing through them, they can accurately sense the actual voltage at the DUT.

The application case
Resistivity is one of the important parameters of semiconductor materials. The resistivity of a single crystal material is a measure of the resistance of a charged carrier to flow through the material. It is closely related to the performance of semiconductor devices. For example, the breakdown voltage parameters of transistors are directly related to the resistivity of silicon single crystal. Four-probe method is a widely used standard test method, the main advantages of which are easy to operate, high accuracy and no strict requirements on the geometric size of the sample.

Battery simulator function enables more accurate analysis of low power consumption
Thanks to the four-quadrant operating characteristics of SMU, the IT2800 Series can not only be used as voltage source, current source, 6 ½ Digital Multimeter, but also built-in professional battery simulator function to help engineers better study the impact of battery characteristics on DUT power consumption and performance reliability. You can quickly generate battery curves by customizing (SOC-VOC-R) or setting conventional parameters. In addition, the initial SOC state of the battery can be specified arbitrarily, without waiting for charging or discharging like using a real battery, which greatly improves the efficiency of R&D and production testing.

Large cache improves measurement throughput
For testing applications requiring high levels of automation and throughput, the IT2800 series SMU features a large cache. The Measure function can store up to 1 million points of output, and the source-measure measurement can store up to 1 million data points. Engineers can read the cache data in batches at the same time of measurement, so as to realize high-speed data acquisition and reduce the data transmission time in single instruction mode.

Multi-channel cascade, easy to achieve parallel testing
The IT2800 series SMU offers multi-channel expansion applications that can connect up to 16 source meter units through fiber ports on the rear backplane to serve as a single, tightly synchronized, multi-channel system. Each channel instrument can run its own independent test sequence to achieve a fully multi-thread test which can meet advanced semiconductor test research as well as batch production line test applications.

Four quadrants and pulse output capability
The IT2800 Series SMU can operate in all four quadrants, where quadrant 1 & 3 are Source mode and quadrant 2 & 4 are Sink mode. The IT2800 Series features a 6 ½ Digital Multimeter with up to 100nV/10fA resolution. The full range of models are available in DC and Pulse output modes. The IT2806 model also offers up to 10A pulse output capability, ideal for testing devices at the semiconductor wafer level, such as VCsels, laser diodes, and leds, protecting DUTs.

Professional I-V Characteristics Software and Semiconductor Parameters Testing Software
The I-V feature software provides a user-friendly GUI, which can be connected to a PC through the standard USB/LAN interface of the device for fast I-V measurement. The software provides multiple test function modules, including IV characteristic analysis, IV tracer, limit test, battery test and battery simulation, etc. Semiconductor parameter testing software provides fast and powerful dynamic and static parameter testing solutions for semiconductors. The software presets various types of semiconductor devices, and users can quickly configure SMU by dragging. The graphical UI interface is simple and easy to operate, which accelerates the testing and research process of engineers.

Banana to triax adapter
Signal interference or excessive loop leakage current will lower the precision for ultra-low current measurement (below nA level). Therefore, it is necessary to ensure the measurement accuracy of extra low current through wiring protection. It requires to use the special triax cables. The IT2800 SMU provides a wealth of optional accessories banana-to-triax adapters and low-leakage triaxial cable accessories to meet the needs of ultra-low current measurement.

When used together, the guard conductor is at the same potential as the center conductor. Since there is no voltage difference, no current flows from the center conductor to the guard conductor, preventing leakage of current from affecting the test results.
