Input/output terminal blocks
Input/Output LO and chassis ground
As shown in
, SMU input/output LOs are available at the rear panel
terminal blocks. Input/Output LOs are not connected between channels and are
electrically isolated from chassis ground.
As shown, there is a low-noise chassis ground banana jack that can be used as a
common signal ground point for Input/Output LOs. This low-noise signal ground
banana jack is connected to the chassis through a Frequency Variable Resistor
(FVR).
The FVR (see
) is used to isolate the SMUs from high frequencies that
may be present on the chassis of the Series 2600. As frequencies on the chassis
increase, the resistance of the FVR increases to dampen its effects.
NOTE
Keep in mind that the chassis should never be
used as a ground point for signal connections.
High frequencies present on the chassis of the
Series 2600 may result in higher noise. The
chassis should only be used as a safety shield.
Use the chassis screw for connections to the
chassis of the Series 2600.

Captive screw (2 per terminal block)
Each terminal block uses two captive
screws to secure it to the rear panel.
