Description
The J2116A is a combined unit with source power amplifier and ground isolator with up to 22.5dB gain and 100dB CMRR. It is used to improve signal-noise in crosstalk and ultra-low impedance measurements. It achieves +20dBm output with +/-9V power and +22.5dBm with +/-12V power. It is compatible with all popular VNAs, including the Keysight E5061B and the OMICRON Lab Bode 500.
The J2116A can be powered from +/-9V – +/-12V using an external power supply or batteries. Power is applied to the unit using connections from a supplied 4-pin Molex connector VEE-GND-GND-VCC (left to right). This is so that an external power supply can be used to power the isolator. SMA connectors are provided to input and output connections.
