Connecting the E5250A Input
To Connect Bias Source to the E5255A Bias Input The E5255A BIAS INPUT connector is a BNC-type connector.
Use BNC cable to connect the bias source to the BIAS INPUT of the E5255A.
If output terminal of the bias source is a banana plug, use a Dual Banana Plug to
BNC Adapter (Agilent part number 1251-2277).
To Connect GNDU to the E5250A Input Ground Unit (GNDU) of Agilent 4142B Modular DC Source/Monitor or Agilent
41501 Expander (for Agilent 4155/4156) is usually connected to GNDU connector
on the connector plate by using Agilent 16493H GNDU cable. This connection
allows current over 1A.
If you want to connect the GNDU through the E5250A to connector plate, test
fixture or DUT, connect the GNDU to the E5250A input as shown below.
CAUTION Make sure current to GNDU is less than 1 A if you connect GNDU to the E5250A.
The maximum input current of the E5250A is 1A.
Required Parts:
Procedure:
1. Connect the adapter to the E5250A SMU INPUT connector (1&2, 3&4 or 5&6)
as shown in Figure 4-7.
2. Connect the GNDU cable between the instrument GNDU connector and the
triaxial connector on the adapter.
