Keysight/Agilent M9111A PXIe High-Speed Source Measure Unit
The Keysight M9111A is a PXIe source measure unit that combines precision voltage and current sourcing along with fast digitizing measurement capability in a single slot. This SMU can operate in two quadrants and deliver 13V at +/-1A or 6V at +/-3A within its 18W power envelope. Because this SMU dynamically alters the output voltage while settling and simultaneously accurately measuring the current from amps down to microamps in less than a millisecond, it is well-suited for high-throughput automated test systems. Every millisecond of test time is valuable for such systems.
The M9111A was engineered specifically for production testing and design validation of power amplifiers and front-end modules. The primary challenge facing designers of these devices is dynamic load currents that cause voltage droop. The control loop in the M9111A will compensate for loads as large as 150 µF of capacitance and recover to ±20 mV in less than 35 µs after a 1.4 A load step. In addition, the SMU has multiple modes of compensation available, so it can be easily configured to work effectively regardless of how many different types of impedance are present (due to wiring, components, etc.) and provide glitch-free output during all changes of operation.
Three user-configurable current measurement ranges (3A, 1mA, and 100µA) allow engineers to precisely characterize the active operating current of their devices as well as the standby leakage current. A built-in digitizer provides simultaneous sampling of voltage and current at rates of 195 kSPS (samples per second), which allows users to stream time-domain waveform data for detailed transient analysis.
Because the M9111A is a key component of Keysight's RF PA/FEM Characterization & Test Reference Solution, it is designed to integrate seamlessly into PXI-based racks that use backplane-triggered synchronization. Both IVI-compliant drivers and a soft front panel provide an easy interface to automate your system under Windows-based environments. As such, engineers depend on the M9111A to significantly reduce test time in power amplifier validation, semiconductor parametric testing, and other applications where the need exists for rapid sourcing of voltage and/or current in conjunction with accurate high-speed current monitoring when operating under pulsed-loaded conditions.
