E4991A-001 DC Bias

Product Status: Discontinued | Currently Supported
This product is no longer available

A replacement for this product is available:


For components with voltage and current dependency, such as RF inductors or ceramic capacitors, the DC bias function (Option E4991A-001) supplies DC voltage (±40 V) and current bias (±50 mA) across the device. You can easily observe your device behavior under various DC bias conditions without using an external DC bias source.
