5730A
Operators Manual
4-4
Connect the Calibrator to a UUT
Warning
The Product can supply lethal voltages. Do not make
connections to the output terminals when any voltage is
present. Placing the Product in standby may not be enough to
prevent shock hazard, since could be pushed
accidentally. Push and make sure that standby is
illuminated before making connections to the output terminals.
The binding posts labeled OUTPUT HI, OUTPUT LO, and AUX CURRENT OUTPUT
deliver voltage, fixed resistance, and current to the UUT (Unit Under Test). The Type
“N” connector on the front panel labeled WIDEBAND delivers the output signal from the
optional 5730A/03 or 5730A/05 Wideband AC Module.
Depending on the output function, output amplitude, and input configuration of the UUT
or meter, connection to the SENSE binding posts, the GUARD binding post, and the
GROUND binding post may also be necessary or recommended. The text in this chapter
explains how and when to use these binding posts.
Recommended Cable and Connector Types
Cables can be connected to the binding posts with banana jacks, terminal lugs, or stripped
insulated wire. To avoid errors induced by thermal voltages (thermal emfs), use
connectors and conductors made of copper or materials that generate small thermal emfs
when joined to copper. Avoid the use of nickel-plated connectors. Optimum results can
be obtained with the 5730A-7003 Low Thermal EMF Test Leads.
Cable requirements depend on the output function, amplitude, and frequency. Table 4-1
gives specific cable recommendations for all applications.
