This section describes how to make and connect the cell cables.
To Keysight Model BT2152A
Two methods of cabling are available:
1. RJ45 to bare wire
Obtain off-the-shelf RJ45 CAT6+ shielded cables. Many lengths are available. For example:
Manufacturer = Belden. Part number = C6F1106010. Maximum allowable cable length = 10 meters.
Cut the cable in the middle. Now, you have two pieces half the previous length. Each piece has an
RJ45 on one side and bare wires on the other.
Connect the RJ45 CAT6+ cables from the instrument to the test fixture.
When using shielded cables like Cat 6A or Cat 7, leave the shield floating at the cell end of the
cable. The cable shield connects to the instrument chassis at the BT2152A end of the cable.
Wire resistance calibration
instrument to allow for more accurate output resistance selections. Wire resistance
calibration is also recommended whenever any RJ45 connector is unplugged, reinserted, or
reseated. Wire resistance must be between 0Ω and 5Ω.
2. RJ45 to RJ45
Obtain off-the-shelf RJ45 CAT6+ shielded cables. Many lengths are available. For example:
Manufacturer = Belden. Part number = C6F1106010. Maximum allowable cable length = 25 meters.
Obtain off-the-shelf RJ45 board mount receptacles. For example: Manufacturer = Amphenol. Part
number = RJSSE-5380-04.
Mount the RJ45 receptacle on the test fixture. Connect the RJ45 CAT6+ cables from the instrument to
the receptacle.
