EMI
The Product inputs, especially the WIDEBAND input, are broadband inputs. This
means you should avoid applying RF signals that can be inadvertently picked up
by cables.
To minimize cable pickup, use short coaxial leads when possible, especially at
test voltages below 2 V. Shielded cables and connectors can minimize the
contribution of EMI to transfer uncertainty. A common-mode choke at the input
terminals is an effective EMI suppressor when using low-level inputs. Do not use
a common-mode choke for the ranges above 2.2 V.
Soldering irons, fluorescent lights, anything with a motor, and all similar things
can radiate EMI. Turn off soldering irons, and keep the Product away from
fluorescent lights and other noise sources.
