Overview

E5061B option 3L5 allows you to apply the DC bias on the source signal of Port 1 or LF output port. The range of DC bias is -40 V to +40 V.

DC Source

When you make S-parameter measurements, the LF output port can be used as the DC supply.

Setting DC Bias

1. Press Sweep Setup > DC Bias Port, then select LF Out or Port 1 which you want to output the DC bias to.

2. Press DC Bias Level, then enter the DC bias level.

Applying DC Bias

1. Press Sweep Setup > DC Bias to turn it ON.

When an ECal is connected to the E5061B USB port or Cal > Calibrate is pressed, DC Bias is turned OFF in order to avoiding the calibration kit having damage.

Using as DC Source

1. Setup the S-Parameter measurements.

2. Press Sweep Setup > DC Bias Port > LF Out.

3. Press DC Bias Level, then enter the DC level.

4. Press DC Bias to turn ON.

5. Make the S-Parameter measurements.
