Sweep function timing
Force-measure timing for a sweep function is similar to the timing for a bias function (shown in
(on page 4-4)), with the following differences:
•
The hold time is repeated at the beginning of each subsequent sweep step.
•
A sweep delay is used in place of the interval.
4210-CVU connections
The 4210-CVU is shipped with four red SMA cables (male-to-male, 100
Ω, 1.5 m). These
characterized cables must be used for connection to the CVU order to achieve optimum performance.
If you have the 4210-CVU-Prober-Kit, you also have four 3 m SMA cables.
Connection notes
•
Use only the supplied red SMA cables for connections to the 4210-CVU.
•
Do not use a mix of cable lengths on different CVU terminals.
•
Use the supplied torque wrench to tighten SMA cable connectors to 8 in. lb.
•
In Clarius, the cable length setting of a test must match the length of the SMA cables used for
your setup.
•
If you need to run connection compensation, do it after setting up connections or after making
changes to existing connections, but before running any tests. See the
(on page 4-10) topic.
•
When making connections from the CVU to the device under test (DUT), make sure the shields of
the SMA cables are connected together as close as possible to the DUT.
•
Use coaxial cables to extend SMA shielding to the DUT, then connect them together.
