ProDAQ 5821 -
Bustec Ltd.
The ProDAQ 5821 series of Signal Conditioning Cards is designed to interface with a variety of sensors, principally RTDs, Thermistors, Cryogenic Diodes and Voltage type sensors. Each version of the 5821 provides the capability of precise 4-wire measurement. In order to achieve this, a precise 500μA constant current source is provided per channel. The current source can be disabled on a per channel basis and is monitored to ensure that current is flowing. The value of the output current is stored on-board after calibration. In order to achieve the highest accuracy the output current may be automatically calibrated 'on-the-fly' using the ProDAQ 3416 24-bit Sigma-Delta ADC card and an on-board precision resistor.

LXinstruments GmbH
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

CBCT -
Manta Test Systems
The CBCT is a variable voltage DC power supply designed specifically to test substation circuit-breaker Open and Close coils. The CBCT uses the substation’s DC power supply to electronically generate a programmable output voltage from 5% to 95% of the source voltage. The CBCT can maintain up to an 80A test current while maintaining 2% or better voltage regulation during the circuit breaker coil operation.

Model 155 -
Lake Shore Cryotronics, Inc.
To reliably characterize developing semiconductor materials and devices, you need high quality current or voltage sources to excite samples. A cleaner (i.e., lower noise) excitation signal enables better measurement of the sample’s response. The MeasureReady™ Model 155 precision I/V sources are ideal for electronic material characterization and other demanding scientific applications requiring a precise, low-noise supply of current or voltage. Supplying 1 W maximum from DC to 100 kHz over a broad output range, these sources provide a solid foundation for I/V curve, Hall effect, and other fundamental measurements. With online software updates, your instrument will always have the most current capabilities. As Lake Shore introduces new options in the future, you can purchase and download them to your instrument. This allows the Model 155 to grow as your measurement needs evolve.

HiRES -
HIGHVOLT Prüftechnik Dresden GmbH
The digital recorders HiRES are used to measure, store, and evaluate signals from up to 64 sources synchronously. Depending on the sensors used voltages, currents, temperatures, mechanical movements and various other signals can be measured. This measurement system features the ability to capture fast transient processes such as those occurring in impulse current tests on electrical devices or during switchgear testing. The system is also capable of measuring semistationary and periodic events such as DC voltage and AC voltage as well as superimposed semistationary, periodic and transient processes.

16-Bit, 8-Channel, 250 kS/s Ch-Ch Isolated PXIe Analog Output Module—The PXIe‑4322 is a channel‑to‑channel isolated analog output module with integrated signal conditioning. The device provides accurate, simultaneous dynamic voltage and current outputs. By combining signal conditioning and D/A converters on the same device, the PXIe‑4322 isolated analog output module delivers a smaller footprint and higher measurement performance. In current mode, the module operates in all four quadrants, so you can both sink and source current. Isolation and higher voltage and current outputs make this module ideal for automotive applications.
