Pulse source-measure connections
TRIGGER OUT of a pulse generator card can be connected to TRIGGER IN of other pulse generator
cards to synchronize the start of pulse outputs. For details on using the trigger connectors, refer to
(on page 4-20).
The cables used for SMU connections are supplied with the SMUs and preamplifiers.
To achieve optimum performance, only use the cables, connectors, and adapters that are included
with Keithley Instruments pulse source or measure kits.
For the pulse source-measure configurations, ensure the 4200A-SCS high voltage is disabled.
This will prevent a safety hazard that could result in possible injury or death because of SMU
voltages greater than 42 V being applied to the device under test or fixture.
Pulse generator connections
The following figure shows a system that uses basic 2-channel pulse generator connections to DUTs.
Use the supplied torque wrench to tighten SMA connections to 8 in. lb.
