Connecting the Model 2290-5 output to a custom test fixture
Keithley Instruments offers several accessories that can help you when building a custom test fixture
or system.
You can use a high-voltage SHV bulkhead connector (Model 2290-5-SHVBH) on your test fixture.
The following sections show you how to connect a Model 2290-5 to a custom fixture and also how to
make connections to the device inside the custom fixture.
Using SHV coaxial connections
If you need to convert from safe high-voltage (SHV) to another connector type, be sure to
only adapt SHV connectors to connectors that are rated to the maximum possible voltage in
your test setup. If you use adapters that are not rated to the maximum possible voltage in
your test setup, electric shock may result.
