Getting Started
Installation
Electrostatic Discharge
Cautions
CAUTION. The electrical data outputs on the optical module are subject to
damage from electrostatic discharge (ESD). To prevent damage from electrostatic
discharge, observe the following guidelines:
Store the module, with the supplied SMA terminations installed, in a static-free
container, such as the shipping container.
Whenever you move the optical module from one instrument to another, use a
static-free container to carry the optical module.
Be sure to only operate the optical module in a static-controlled environment
(grounded conductive table top, wrist strap, floor mat, and ionized air blower).
Always use a grounded wrist strap (provided with your instrument) when
installing, removing, or handling an optical module or making connections.
Discharge to ground any electrostatic charge on cables before attaching the cable
to the optical module.
Correct Module Handling
Guidelines
CAUTION. Take the following precautions to avoid damaging your optical module:
Never install or remove a module when the instrument is powered on (front-panel
On/Standby power switch is ON).
Do not drop the module since damage and misalignment of the photodiode optical
assembly can result. Store the module in a secure location when not in use.
Place the protective cap(s) on the optical and electrical input connectors when
the module is not in use.
To prevent loss of optical power or damage to the optical connectors, keep the
connectors clean at all times.
Check that all connectors, jumpers, and protective caps are clean before
connecting them to the module. (See page 18, Cleaning the Optical Connectors.)
