1-5 Electrostatic Discharge Caution
The DS2831 Digital TV Spectrum Analyzer, like other high-performance instruments, is susceptible to
electrostatic discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which
may damage the DS2831 input circuitry. DS2831 operators must be aware of the potential for ESD damage
and take all necessary precautions.
It is recommended to discharge the static by connecting a short or load device to the cable or antenna
before connecting them to the DS2831. It is important to remember that the operator may also carry a
static charge that can cause damage. Following the practices outlined in the above standards will ensure
a safe environment for both personnel and equipment.
•
When connecting a coaxial cable to the instrument for the first time that day, the center conductor
of the cable and the outer braided shielding layer should be quickly grounded.
•
During service, ensure that the technician is grounded before removing inner components or pulling
out connecting cables.
•
Ensure that the instrument is well grounded, so as not to store any static charges.
•
Electrostatic protection of this instrument is up to standards of 6KV contact and 8KV air-gap.
