Atto Sense and Switch Unit
Atto Sense and Switch Unit
Only for the B1500A. To use the Atto Sense and Switch Unit (ASU), it must be
connected to the SMU which is connected together when the calibration is
performed. Using the ASU permits use of the 1 pA range. Also the ASU can switch
the measurement resources, SMU or an instrument connected to the AUX input
connectors. The ASU can configure two setups shown in
Figure 4-22. When the
B1500A is turned on, the ASU will be the Setup 1 condition. See Agilent B1500A
User’s Guide to install the ASU properly.
The ASU has input connectors, one triaxial and two coaxial. The triaxial connector
must be connected to the SMU Force, and the coaxial connectors must be connected
to an instrument. Also the ASU has the control connector to be connected to the
SMU by using the ASU cable.
