6.4 Measurement Non-Linearity
6.5 Shutter/Trigger
The Ossila Source Measure Unit has two additional voltage measurement channels marked as Vsense1 and
Vsense2. They are designed to accurately detect small voltages while simultaneously having a wide dynamic
range of ±10 V.
Table 6.5 lists the specifications of these additional channels.
The non-linearity in the measurement of the Ossila Source Measure Unit is kept well below the
measurement accuracy of every range. Such non-linearity is common due to different amplification stages
and analogue digital conversion processes.
The Shutter/Trigger can be used either as an input or an output. It can be used to send a trigger signal to
other instruments or configured to wait for a trigger from other instruments. The voltage level of the Shutter/
Trigger is 5 volts and can source and sink up to 30 mA of current; higher currents may result in damage to
the unit.
Warning: Do NOT apply currents to a SMU that are greater than the maximum current of the range
that is active, as this may result in damage to the unit.
Note: the Vsense module shares a ground plane with the SMU module of the same number (i.e.
Vsense 1 shares a ground plane with SMU 1) and hence is not isolated.
