Device Capacitance Selector (N1272A) specification
The N1272A simplifies 2 and 3 terminal device capacitance measurements by automatically creating the correct configu-
ration of test resources (including adding any needed DC blocking capacitors and AC blocking resistors) for a specified
capacitance measurement. To measure packaged device capacitance the N1273A Capacitance Test Fixture is also neces-
sary. However, the N1272A can be used directly with a probe station to measure on-wafer device capacitances.

Measurement accuracy for 2-terminal device (Supplemental characteristics)
The accuracy of the supplemental characteristics is defined at the output terminals of the TO socket adapter in the
N1273A Capacitance Test Fixture when the N1272A is connected to B1505A with the 1.5 m CMU cable and the N1273A
system cable.
