NOTE
CAUTION
Gate terminals are designed for using with the Selector Output terminals. See
Figure 3-11. High should be connected to the gate or base terminal of a DUT.
Low should be connected to the source or emitter terminal of the DUT.
Open the Gate terminals for the ultra high voltage measurement using UHVU.
3. Selector Output
See Figure 3-11 and
For connecting a prober station, use the N1254A-524 system cable.
Open the terminals for the ultra high voltage measurement using UHVU.
a. Low Force and Low Sense output terminals
Force and Sense must be connected together at the low terminal of a DUT.
Use the banana-banana wire (N1254A-522) for performing the ultra high
current measurement using UHCU.
b. High Force and High Sense output terminals
Force and Sense must be connected together at the high terminal of a DUT.
Use the banana-banana wire (N1254A-522) for performing the ultra high
current measurement using UHCU.
c. Guard terminal
Guard (high level) must be opened. You may extend it as close as possible to
a DUT terminal for reducing the leakage current of the extension cable.
d. Chassis common terminal
Use for grounding or shielding.
Selector may emit a noise sound during operation. However it is not abnormal
status.
4. Bias Tee High and Low terminals
Output terminals internally connected to the Bias Tee High and Low input
connectors on the rear panel.
High and Low must be connected to the high and low terminals of a DUT
respectively. Use SHV(plug)-SHV(plug) cable (N1254A-512) and
SHV(jack)-banana adapter (N1254A-513) for connection.
Open the Bias Tee terminals for the ultra high voltage measurement using UHVU.
