Keysight Technologies M9111A PXIe High-Speed Source/Measure Unit 13 V, ± 1 A or 6 V, ± 3 A, 18 W Data Sheet 02 | Keysight | M9111A PXIe High-Speed Source/Measure Unit - Data Sheet Source Faster, Measure Faster Change voltage, stabilize, and make accurate measurements in less than 1 ms! In automated test environments, the adage “time is money” is never more prevalent. Thus, speed of test is critical. The faster you are able to test a device, the more money you will save. Keysight’s M9111A PXIe High-Speed Source/Measure Unit (SMU) was specifically designed for this environment. It helps you achieve high-throughput, while maintaining measurement quality in design validation and production test of power amplifiers. The M9111A can change its output voltage, stabilize that voltage, and accurately measure current from Amps down to micro-Amps all in less than 1 ms so that you can move on to the next test as quickly as possible. As part of Keysight’s RF PA/FEM Characterization and Test Reference Solution, this combination provides exceptional performance for the demanding requirements of testing modern power amplifiers (PAs) and front-end modules (FEMs). Overview The M9111A is a 1-slot, 2-quadrant PXIe module that delivers up to 13 V, ± 1 A or up to 6 V, ± 3 A, 18W. The M9111A SMU combines the capabilities of a voltage source, a current source, an ammeter and a voltmeter to provide stable, glitch-free sourcing and sinking, and high accuracy measurements. It offers: –– High-speed changes in voltage with fast settling times –– High-speed recovery and low-voltage droop when the DUT pulls fast slewing current pulses –– High-speed, accurate low level-current measurements, such as leakage current Speed up test with high speed SMU output When it comes to speed, the M9111A PXIe High-Speed Source/Measure Unit achieves performance unlike a typical DC power supply; it’s up to 20x faster than previous generation Keysight SMUs. The M9111A quickly changes voltage in 10-50 microseconds depending capacitance of the device under test (DUT), and that voltage quickly settles to its programmed value to quickly provide a stable output. Decrease test time by minimizing the wait time for a power supply voltage to settle with the M9111A, so the rest of the test system can continue to do its job. 03 | Keysight | M9111A PXIe High-Speed Source/Measure Unit - Data Sheet Stable Voltage even with Dynamic or High Capacitive Loads Power amplifiers and other components present a unique testing challenge: they draw rapid pulses of current. By offering superior transient performance, the M9111A SMU dramatically reduces the transient voltage drop due to pulsed loading and recovers quickly to its program voltage (even with capacitances of up to 150 μF). The M9111A provides industry-leading output stability under extreme, dynamic load conditions so that you never have to worry about your power source interfering with your measurements. The M9111A SMU’s glitch-free operation ensures that during programmed output or measurement ranges changes, the M9111A’s output voltage and current remain steady and the DUT remains unaffected. Further, to provide this output stability, the M9111A SMU has user-selectable compensation modes that improves usability and productivity by instantly configuring the SMU’s feedback loop to match the impedance of the system (DUT and wiring paths). Accurately Measure Leakage and Dynamic Currents Measuring static current accurately can be a challenge. Measuring dynamic currents from µA level to A is an even greater challenge. Depending on the level of current, a different precision measurement resistor must be used, representing a measurement range in the SMU. The three current measurement ranges (3 A, 1 mA, and 100 µA) of the M9111A makes it tuned to quickly and accurately measure the different operating states and power consumption of a device. The built-in measurement system enables fast measurement of low currents down to µA, even if the DUT has a large capacitor (up to 150 µF) and the built-in high-speed digitizer measures voltage and current every 5.12 µs (~200 ksamples/s). Triggering The M9111A PXIe SMU utilizes the PXI chassis backplane trigger-in to receive triggers to start a measurement. 04 | Keysight | M9111A PXIe High-Speed Source/Measure Unit - Data Sheet Drivers and Soft Front Panel To simplify system development, the M9111A comes with IVI.COM and IVI.C drivers for 32-bit and 64-bit Windows OS. The soft front panel interface provides an easy way to monitor, configure, and control the M9111A SMU. Figure 1.
