Front Panel Connectors
WIDEBAND Connector
A type “N” connector that provides a connection
point for output from the -03 Wideband AC option.
Wideband output specifications are stated for
output levels present at the end of its three-foot
50Ω coaxial cable terminated into a 50Ω purely
resistive load. The connector shell is connected to
chassis ground.
GND Binding Post
If the Calibrator is the location of the ground
reference point in a system, the GND binding post
can be used for connecting other instruments to
earth ground. (The chassis is normally connected
to earth ground through the three-conductor line
cord instead of through the earth ground binding
post.)
V GUARD Binding Post
Provides an external connection point for the
internal voltage guard. For a UUT with floating
(ungrounded) inputs, the C GUARD should be
connected to LO internally (x key toggled off).
For a UUT with a grounded input, the V GUARD
must be externally connected to the grounded UUT
input (x key toggled on). The maximum
allowable potential between the V GUARD
connector and chassis ground is 20V peak.
