Tools supplied with the 4200-SCS FLASH package
NOTE Use the supplied torque wrench to tighten each connection as it is assembled.
Always connect and torque adapter/cable assemblies before attaching the assembly
to the instrument cards.
Pre-torquing eliminates any non-axial stress on the bulkhead connectors on the SMU
or pulse cards, which could cause damage to the cards installed in the 4200-SCS
chassis, requiring repair.
To remove the LEMO triax-to-SMA adapter from a SMU, pull on the knurled silver
portion of the connector to release the latches and permit the adapter to separate
from the SMU connector.
CAUTION Failure to fully disengage the LEMO adapter latches may result in damage
to the adapter and/or the SMU, requiring repair.
The connection instructions below assume a four channel 4200-SCS FLASH
system, consisting of two 4205-PG2 cards (4 pulse channels) as well as four
SMUs, either 4200-SCS SMU or 4210-SMU, with SMU preamps removed (see
Figure 3-83 or Figure 3-84).
To test on-wafer devices, there are various ways to connect the supplied SMA
cables to the probe manipulators. For the direct connect method (see Figure 3-95
and Figure 3-96) or switch method (see Figure 3-97), adapters convert the BNC
cabling to the Triax connector compatible with many types of probe manipulators.
