DESCRIPTION:

The Port Saver family of DC blocks incorporates new features designed to protect your most value instruments while also greatly improving performance. Port Saver includes inrush currently limiting, which together with the transient protection, limits the voltage that appears at the instrument when a DC voltage is applied. Pre-charge allows the block to charge even without a connection to the instrument, eliminating the inrush. Self-discharge allows the DC block to discharge even if it is removed from both the source and the instrument, eliminating potential damage from energy stored in the block.

Typical RF blocks are based on ceramic capacitors, which exhibit AC and DC bias effects, making it very difficult to calibrate, as well as ferro-resonant noise. Port Saver blocks do not exhibit DC or AC bias effects, resulting in greatly improved calibration and measurement accuracy and do not exhibit ferro-resonant noise, making them quieter.

Port Saver DC blocks can easily be customized for different voltages and bandwidth. Please inquire with Signal Edge Solutions at info@signaledgesolutions.com
