Output Connection
To Use High Voltage Bias-T
The high voltage bias-T is used to perform capacitance or impedance measurements using
DC bias of up to ± 3000 V. The bias-T High terminal is internally connected to the MF
CMU Hpot and Hcur input connectors. And the bias-T Low terminal is internally
connected to the MF CMU Lpot and Lcur input connectors.
• Required parts:
N1254A-512 SHV(plug)-SHV(plug) cable, 2 ea.
N1254A-513 SHV(jack)-banana adapter, 2 ea.
N1254A-508 or N1254A-509 connection wire, 2 ea.
• Connection:
See Figure 2-9 .
1. Attach the SHV-banana adapter to the SHV cable, and make two cables.
2. Connect a cable (solid line) between the bias-T Low terminal and the low terminal
of DUT.
3. Connect a cable (solid line) between the bias-T High terminal and the high terminal
of DUT.
4. Connect a wire (dotted line) between a SMU Force output terminal and the DC Bias
Input High terminal. Use MPSMU for DC bias of up to ± 100 V, HPSMU for ± 200
V, or HVSMU for ± 3000 V.
5. Connect a wire (dotted line) between the SMU Guard output terminal and the DC
Bias Input Guard terminal.
