NOTE
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
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
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

chassis, requiring repair.
Failure to fully disengage the LEMO adapter latches may result in damage
to the adapter and/or the SMU, requiring repair.
