Module 2
Basic Measurement
To prevent shock hazard, the B1500A will not operate above 42 V, unless you connect the interlock
circuit.
The interlock connection is required when the voltage exceeds 42 V or when the program memory is
used in a control program.
The 16442A/B test fixture has the interlock circuit internally which makes this short by closing a lid
activated switch.
You must make the circuit to your prober to comply with US OSHA safety standards. The switch on
the prober should be mounted into the access door of the shield box.
If you want to connect to the BNC type interlock connector on the 16088B, your fixture or prober,
use the 16435A Interlock Cable Adapter. The 16435A provides a BNC cable and a small adapter
box which is used to join the BNC cable and the interlock cable furnished with the B1500A.
If you want to wire your own cable or fixture, these Keysight part numbers may be used:
1252-1419 Female 6-pin plug connector
1252-1418 Male 6-pin cable connector
