Beschreibung

The Picotest J2170B power adapter is specially designed for use with the Picotest J2110A, J2111A, J2112A and J2113A signal injector products. The supply combines a universal worldwide input (100 to 240 VAC ) with two high performance linear regulators.
While there are many off-the-shelf power supplies available that can provide a universalinput voltage and 12V output voltage, they do not provide the same performance as theJ2170B. Most switching regulators produce significant ripple at and above 100kHz. Thisripple passes through the PSRR of the internal opamps, reducing the noise floor. While thismay work in many applications, it is less than ideal. Typical switching power supplies andeven typical linear regulators have a high output impedance at 40MHz, due to the ESL of theoutput capacitors and the nature of the control loop. The J2170B uses a discrete design approach, offering very low output impedance, stableperformance with large ceramic decoupling capacitors and ultra high PSRR compared withtypical off-the-shelf devices. To maintain a good noise floor for various measurements, thepower supply must have very low noise.
