功能說明

The 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 universal input voltage and 12V output voltage, they do not provide the same performance as the J2170B. Most switching regulators produce significant ripple at and above 100kHz. This ripple passes through the PSRR of the internal opamps, reducing the noise floor. While this may work in many applications, it is less than ideal. Typical switching power supplies and even typical linear regulators have a high output impedance at 40MHz, due to the ESL of the output capacitors and the nature of the control loop.

The J2170B uses a discrete design approach, offering very low output impedance, stable performance with large ceramic decoupling capacitors and ultra high PSRR compared with typical off-the-shelf devices. To maintain a good noise floor for various measurements, the power supply must have very low noise.

What's included:

1. J2170B High PSRR Regulated Adapter
2. User manual
