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.
