National Instruments 783761-01 PXI Source Measure Unit
The National Instruments 783761-01 (or PXIe-4137) is a top-notch PXI Source Measure Unit (SMU). This unit supports 4-quadrant operation that offers the ability to source up to 40 W of DC power and pulse up to 500 W. It utilizes advanced analog-to-digital converter technology for high-precision measurements with a current resolution of 100 fA and acquisition speeds up to 1.8 MS/s. The 783761-01 features SourceAdapt technology that enables users to fine-tune the transient response for optimal stability and accuracy across various load characteristics.
This 783761-01 SMU operates on ±200 V DC voltage and its current requirement range is ±1 A DC along with a pulse current capability up to ±3 A. It provides robust channel-to-earth ground isolation with continuous 250 V DC, CAT I, and a withstand capability of 1,000 V RMS. The unit includes a guard output with cable guard functionality, a nominal output impedance of 3 kΩ, and a typical offset voltage of 1 mV.
The 783761-01 is recommended for calibration at one-year intervals and requires a power supply of 3.0 A from the 3.3 V rail and 6.0 A from the 12 V rail. It offers bias voltage limits up to 200 V and current limits up to 1 A along with pulse voltage limits up to 160 V. The module supports a wide range of voltage and current source and sink ranges that make it suitable for applications such as IC testing, PMICs, RFICs, LEDs, and optical transceivers.
Accuracy and resolution are the key features of this NI 783761-01 SMU. The voltage programming accuracy of this module is ±0.025% and current programming accuracy is up to ±0.04%. This SMU offers a transient response time of less than 70 μs for load changes. The device also features comprehensive protection mechanisms that include overcurrent, overvoltage, and overtemperature shutdowns, along with a safety interlock to disable high voltage output when necessary.
The NI 783761-01 unit is a compact 3U, one-slot PXI Express/CompactPCI Express module with dimensions of 2.0 cm × 13.0 cm × 21.6 cm. The overall weight of the unit is approximately 428 g. Environmental characteristics of the 783761-01 unit ensure reliable operation within a temperature range of 0 °C to 55 °C and storage from -40 °C to 71 °C. The allowable humidity range of this SMU is 10% to 90% (noncondensing). The PXIe-4137 complies with international standards for electromagnetic compatibility and safety.
