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.
