Keysight Technologies has introduced its first PXI Express source/measurement unit, the M9111A , for design verification and production testing of next-generation power amplifiers and front-end modules supporting mobile phones and wireless connectivity.
The high-speed M9111A changes voltage, stabilizes and accurately measures microampere currents, all in 1 ms. The PXIe SMU is 20 times faster than Keysight's previous standalone SMUs and is smaller.
Germany is the senior director of mobile technology chip test Giampaolo Tradioli said: "In the power amplifier automated test environment, test speed is very important launch M9111A PXI very useful to enrich the product line, can meet the challenges of speed tests it not only has high speed. Features such as output and bumpless operation, and excellent stability, even when the capacitance reaches 150 μF, make it ideal for power amplifier testing of mobile phones and mobile phones."
Power amplifiers bring fast pulse currents, but the M9111A has the industry's unparalleled transient performance to meet this challenge. The M9111A SMU significantly suppresses voltage sags caused by pulsed loads and quickly returns to the programmed voltage.
Traditional SMUs become unstable under extreme, dynamic load conditions. But the M9111A has industry-leading output stability, so there's no need to worry about the power supply affecting the measurement. The undisturbed operation ensures the safety of the device under test when the output and measurement range are changed. Even if high capacitance occurs, there is no need to worry. The output voltage and current remain stable, so the device under test will not be damaged.
The single-slot, two-quadrant PXIe SMU module provides up to 18W of power and supports 13 V, ±1 A or 6 V, ±3 A mode. Functionally, the M9111A can be used not only as a voltage source and current source, but also as an ammeter and voltmeter. The measurement capabilities of the M9111A include:
? Has fast settling time and can measure high speed changes of voltage
? When the pulse current of the device under test changes abruptly, it can achieve fast recovery and reduce voltage drop.
• Perform low current measurements such as leakage current quickly and accurately
The M9111A is part of Keysight's RF power amplifier and front-end module reference solution, which quickly and comprehensively characterizes next-generation power amplifier modules such as power amplifier devices for S-parameters, demodulation, power, adjacent channel power and Measurements such as harmonic distortion.

There is no requirement for the shape of the two-core Argentina plug, only that the distance from the pin to the edge is not less than 8mm, and the maximum size of the three-core Argentina plug is 38mm. The power cord plug looks like an Australian plug and also looks like a national standard plug. However, the size of the plug of his plug is different from that of Australia. The length of the pin is 1 mm, so the size is also a bit different. The most important point is that the plug direction is different and the grounding direction is opposite.
