Key Features
Overview
Precision Mixed Mode Technology
The Picotest P9611A represents a breakthrough in programmable DC power supply design, delivering the combined benefits of both linear and switched-mode technologies in a single 150W unit. This innovative mixed-mode approach provides exceptional efficiency whilst maintaining the low-noise characteristics essential for sensitive circuit testing.
Engineered for professional electronic design engineers, the P9611A offers continuous autoranging capability from 0-60V and 0-6A, eliminating the need for manual range selection. The supply delivers outstanding programming accuracy of 0.05% + 10mV with ultra-low ripple noise below 3mVp-p (20Hz-20MHz bandwidth), making it ideal for testing noise-sensitive analogue circuits and precision instrumentation.
Advanced Features for Modern Testing
Key advantages include rapid transient response time under 50μs, optical knob control for enhanced durability, and comprehensive protection including OVP, OCP, and short-circuit withstand capabilities. The unit supports programmable sequencing with eight programmable points and offers optional GPIB and USB interfaces for automated test system integration.
The P9611A is part of the P961xA series, alongside the P9610A (36V/7A model), providing engineers with scalable solutions for various voltage and current requirements. Its compact, lightweight design (under 2.5kg) and stackable form factor maximises bench space efficiency whilst delivering professional-grade performance.

Questions and Answers
-
How Does the P9611A Compare to Traditional Linear Power Supplies?
The P9611A keeps the low noise of a linear supply, but its mixed-mode design gives higher efficiency and lower weight. Its transient response (<50μs) matches that of the Keysight E3632A linear supply, and it offers higher power density in a more compact case.
-
What Are the Programming Accuracy and Resolution Specifications?
P9611A programming and read-back specifications:
- Voltage: programming accuracy 0.05% + 10mV, resolution 1mV, read-back accuracy 0.05% + 5mV
- Current: programming accuracy 0.2% + 10mA, resolution 1mA, read-back accuracy 0.15% + 5mA
-
Is the P9611A Suitable for High-current Applications Requiring DC Bias?
Yes. The P9611A delivers up to 6A output current with 1mA programming resolution, which suits DC bias applications. It pairs with Picotest accessories such as the J2103A Power Stage Isolator for power supply testing and the J2121A High Power Line Injector for inductor measurement under DC bias.
-
What Are the Key Differences Between P9611A and P9610A Models?
The P9611A provides 0-60V/0-6A (150W), while the P9610A provides 0-36V/0-7A (108W). So the P9611A suits higher-voltage circuits and the P9610A gives more current. Both share the same mixed-mode technology, programming accuracy and protection features.
-
How Does the Optical Knob Control Enhance Reliability?
The P9611A's knob uses photo-interrupted optical sensing instead of a traditional potentiometer. There's no mechanical wear and it doesn't get dirty, so it won't degrade the way potentiometers do. It provides numerical and directional control.
-
How Does the Autoranging Feature Benefit Test Applications?
Autoranging lets the P9611A deliver full power across its whole voltage and current range without manual range selection. You get 100% power availability at any operating point within the specifications, so one supply can do the job of several, reducing equipment costs.
-
What Makes the P9611A Suitable for Noise-sensitive Applications?
Ripple and noise are below 0.5mVrms and 3mVp-p (20Hz-20MHz bandwidth). This suits sensitive analogue circuits, audio equipment and precision measurement instruments that need clean power.
-
Can the P9611A Be Integrated Into Automated Test Systems?
Yes. The P9611A has USB and GPIB (optional) interfaces and accepts SCPI commands. It's code-compatible with the Keysight E3632A, which simplifies integration into existing test systems. It also offers programmable sequencing with eight programmable points, plus remote monitoring.
-
What Protection Features Are Included in the P9611A?
The P9611A has:
- overvoltage protection (OVP)
- overcurrent protection (OCP)
- over-temperature protection (OTP)
It withstands continuous short circuits, or repetitive short circuits up to 13 times per second. These features protect both the supply and the device under test during faults.
