- Marvin Test Solutions announces the release of its GX3116e Device Power Supply (DPS) module.
- This 16 channel PXI board offers power supply capabilities for devices under test, source and measure (SMU).
The GX3116e is a precision four-quadrant, 16 channel Device Power Supply (DPS) capable of forcing and measuring both voltage and current on all 16 channels independently. It incorporates two electrically isolated groups of 8 programmable voltage/current source and measurement channels.
Three programmable current ranges are available: 2.56 mA, 25.6 mA and 512 mA; the voltage output range is determined by the current range selection. In low current ranges the DPS can force between -2 V and 10.5 V, and in high current mode (>25.6 mA), the DPS can force between 0 V and 9.5 V. Multiple channels can be ganged together to achieve higher current levels, with a maximum current output of 2 A per bank; additionally, both banks can be ganged together to extend the total available output current to 4 A.
In constant voltage mode, the DPS forces a voltage whose current output is determined by the programmable source/sink current limits. The output voltage can be sensed either locally or remotely utilizing Kelvin connections available on a per channel basis. Kelvin connections provide the best voltage accuracy at the device under test (DUT), ensuring that the DUT receives the required excitation levels independent of cabling and other interconnects.
Each channel has a ground sense which can be connected to local ground or to the DUT ground. The ground sense, when connected to the DUT, is capable of tracking the DUT ground level and adjusting its output accordingly.
In constant current mode the DPS forces a current, and the voltage output is limited by programmable high/low voltage limits. Output voltage and current levels are set with 16 bits of resolution, and measurement readback with 24 bits of resolution. Each channel can be protected and disabled when an over current, over voltage or over temperature condition is detected.
The GX3116e is supplied with a featured virtual instrument panel that can be used to interactively program and control the instrument, as well as documentation and online help files. MTS also delivers GtLinux, a software package providing support for Linux 32/64 operating systems.
