4-2 Keysight B1505A Configuration and Connection Guide
N1272A and N1273A Connection Guide
This chapter describes the required information for connecting Keysight B1505A,
N1272A, N1273A, and a device under test (DUT).
• "Input Connection"
• "Output Connection"
The N1273A capacitance test fixture is a test fixture used for capacitance measurements of
packaged devices. The fixture can be connected to GNDU, MFCMU, HVSMU, and
MPSMU via the N1272A device capacitance selector.
The N1272A selector is connected between the mainframe and the test fixture. And it is
used for switching the IV measurement and the CV measurement, and has a built-in
GNDU protection adapter and a built-in MFCMU protection adapter.
General specifications of the N1272A/N1273A are listed below.

WARNING To avoid electrical shock and instrument damage, turn the all instruments off before
connecting or disconnecting measurement cable.
WARNING There are potentially hazardous voltages of up to ± 3000 V (HVSMU) or ± 100 V
(MPSMU) at the Force, Guard, and Sense terminals. To prevent electrical shock, do
not expose these lines.
WARNING To prevent electrical shock during use, connect the Interlock cable (see "To Connect
Interlock Circuit" on page 4-3 ).
WARNING The B1505A is heavy and requires a two person lift.
CAUTION Do not grab the fixture cover when lifting the N1273A.
CAUTION Never connect the Guard terminal to any output, including circuit common, chassis
ground, or any other guard terminal. Connecting anything may damage the module.
CAUTION Never connect the HVSMU Force and Guard terminals to any output, including circuit
common, chassis ground, or any other module terminal. Connecting other module may
damage the connected module.
