Chassis
Signal Ground is a local signal ground and defined as
the Low-Noise Chassis Ground Banana Jack.
Chassis is defined as the metal chassis of the Series 2600.
1) Frequency Variable Resistor (FVR) Isolates
the SMUs from high frequencies on the chassis.
For DC to 60Hz, the FVR is a virtual short (zero
ohms).
2)
DO NOT
use the Chassis Screw terminal to
make signal connections to external circuitry.
High frequency (>1MHz) on the chassis may
result in higher noise at the output.
Chassis Screw terminal is connected to the metal chassis of the
Series 2600.
