Installation
Connecting the R-Box to the 4155/4156
Before connecting the R-box to the 4155/4156 and 41501, turn off the instruments.
1. Connect the To R-Box terminal on the 4155/4156 rear panel to the Control
terminal on the R-Box rear panel using a 3.0 m or 1.5 m control cable.
2. Connect the instrument measurement terminals to the R-Box input terminals as
shown below:
3. Connect the R-Box output terminals to the input terminals of the 16442A test
fixture or an connector plate using 40 cm triaxial cables as shown below:
When you use the connector plate, use a low-noise coaxial cable (Agilent part
number: 8120-3674) from the connector plate to DUT. If you use insufficiently
insulated cables, leakage current may occur.
