Figure 23: Input/output connectors
Input/output LO and chassis ground
As shown in the following figures, 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.
The chassis should never be used as a ground point for signal connections. High frequencies (more
than 1 MHz) present on the chassis of the 2600B 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 2600B. For
2634B, 2635B, and 2636B, connect to ground on the ground module, not to the chassis screw.
