To Connect High Voltage Bias Tee
Keysight N1260A high voltage bias-tee is used to perform the high voltage C-V
measurement. The C-V measurement of up to 3000 Vdc can be realized by using the
bias-tee, MFCMU, and HVSMU. The N1260A should be installed near your DUT
interface as shown in Table 5-1 on page 5-5. Also see Figure 5-9 for connection example.
The N1260A is also used for the high voltage C-V measurement using the N1265A test
fixture. It must be connected between the MFCMU and the N1265A. Then use two
N1254A-518 SHV cables to connect the N1260A output to the N1265A Bias Tee input.
The N1260A input connection is same as Table 5-18. Ignore Table 5-19.
Table 5-18 To Connect N1260A Input
NOTE Turn the B1505A off before connecting the CMU cable.
Connect HVSMU to obtain DC bias input. Because the bias-tee cannot pass the MFCMU
internal DC bias.
