Connecting 8-Channel Shielded Coaxial Cable
This section introduces Agilent 16494E wide temperature 8-channel shielded
coaxial cable, and explains how to connect the 16494E to the Device Under Test
(DUT).
WARNING Do not connect the 16494E cable to the E5255A or any instrument until
connecting to the DUT as described below. If you ignore this warning, you
maybe exposed to dangerous voltage.
The 16494E coaxial cable is used to connect the E5255A output directly to the DUT,
DUT socket, or any fixture you want without using the connector plate. One 16494E
is used for one 8-channel output connector of the E5255A. To use 24 output
channels (three 8-channel output connectors), you need three 16494Es.
Instrument Side The instrument side of the 16494E cable can be connected directly to the E5255A
output.
DUT Side Solder the open side of the 16494E directly to DUT, DUT socket, or your test fixture
as shown in Figure 4-1.

NOTE For highly accurate current forcing and measurements with minimized leakage,
extend the guard to surround the signal lines as close as possible to the DUT.
