Agilent Technologies B2201A manual When more than ±40 V is forced from an SMU in the 4155/4156

Installation

Output Connections

	The 4155/4156 semiconductor parameter analyzer's Intlk connector provides the
	interlock signal and a LED drive signal. If a LED is connected between pin 4 and
	pin 5 (or 6) of the interlock connector, the LED lights to indicate high voltage output
	when more than ±40 V is forced from an SMU in the 4155/4156.

To Connect Interlock Circuit to Instrument

Before beginning the measurement, connect the interlock circuit to the instrument’s interlock connector as follows.

•For the instruments which has a BNC-Type interlock connector:

1.Get the following parts.

•Agilent 16493J Interlock cable, 1 ea.

•Agilent 16435A Interlock cable adapter, 1 ea.

2.Connect the 16493J interlock cable between the interlock circuit and the 16435A adapter.

3.Connect the BNC cable (furnished with the adapter) between the adapter and the instrument’s interlock connector.

•For Agilent 4155/4156/E5260/E5270:

Connect the 16493J interlock cable between the interlock circuit and the instrument’s interlock connector. You can connect it directly without using any adapter.
