Frequently Asked Questions
Have a Question?
-
How does the optical knob control enhance reliability?
The P9611A features an innovative optical knob control system that uses photo-interrupted technology instead of traditional potentiometers. This design eliminates mechanical wear, prevents contamination from dust or moisture, and ensures consistent, precise control throughout the product's lifetime. The optical system provides numerical capability and directional control for enhanced user experience.
-
What are the key differences between P9611A and P9610A models?
The P9611A provides 0-60V/0-6A (150W) output compared to the P9610A's 0-36V/0-7A (108W) specification. The P9611A offers higher voltage capability making it suitable for testing higher-voltage circuits, whilst the P9610A provides higher current output. Both share the same mixed-mode technology, programming accuracy, and protection features.
-
Is the P9611A suitable for high-current applications requiring DC bias?
The P9611A delivers up to 6A output current with 1mA programming resolution, making it excellent for DC bias applications. It pairs effectively with Picotest accessories like the J2103A Power Stage Isolator and J2130A DC Bias Injector for advanced power supply testing and inductor measurement under bias conditions.
-
What are the programming accuracy and resolution specifications?
The P9611A provides exceptional programming accuracy of 0.05% + 10mV for voltage and 0.2% + 10mA for current. Programming resolution is 1mV for voltage and 1mA for current, with read-back accuracy of 0.05% + 5mV and 0.15% + 5mA respectively. This precision enables accurate characterisation of sensitive devices and components.
-
How does the P9611A compare to traditional linear power supplies?
Whilst maintaining the low-noise advantages of linear supplies, the P9611A offers superior efficiency, reduced heat generation, and lighter weight through its mixed-mode design. It provides faster transient response (<50μs) compared to many linear supplies and delivers higher power density in a more compact form factor, making it ideal for modern test applications.
-
What protection features are included in the P9611A?
The P9611A incorporates comprehensive protection including overvoltage protection (OVP), overcurrent protection (OCP), and over-temperature protection (OTP). It can withstand continuous short circuits or repetitive short circuits up to 13 times per second. These protection features safeguard both the power supply and the device under test from damage during fault conditions.
-
Can the P9611A be integrated into automated test systems?
Yes, the P9611A supports both USB and GPIB interfaces (optional) with SCPI command compatibility. It's code-compatible with the Keysight E3632A, simplifying integration into existing test systems. The unit also features programmable sequencing with eight programmable points for automated test procedures and remote monitoring capabilities.
-
What makes the P9611A suitable for noise-sensitive applications?
The P9611A achieves exceptional low-noise performance with ripple and noise below 0.5mVrms and 3mVp-p in the 20Hz-20MHz bandwidth. The mixed-mode design isolates switching noise through the linear regulation stage, making it ideal for testing sensitive analogue circuits, audio equipment, and precision measurement instruments that require clean power sources.
-
How does the autoranging feature benefit test applications?
The P9611A's autoranging capability automatically optimises power delivery across the entire voltage and current range without requiring manual range selection. This ensures 100% power availability at any operating point within the specifications, eliminating the need for multiple power supplies and reducing equipment costs whilst maximising test flexibility.
