80C00 Optical Sampling Module Operation
NOTE
. These are not comprehensive operating instructions; consult the documen-
tation map on page 2–12 to find other sources of operating instructions.
NOTE
. Proper operation of 80C04 modules requires that the operating–system
software installed on the main instrument is version 1.1.0 or greater. To display
the version installed, select About TDS/CSA8000 from the Help menu of the main
instrument.
CAUTION.
To avoid damaging your optical sampling module, handle your optical
sampling module carefully at all times and take the following precautions:
Do not drop your sampling optical since damage and misalignment of the
photodiode optical assembly can result. Store the sampling optical in a secure
location when not in use.
Replace the protective cap on the input connector when the sampling optical is
not in use.
To prevent loss of optical power or damage to the optical connectors, keep the
connectors clean at all times. Also insure that all connectors and jumpers
attached to the inputs are clean prior to insertion.
To keep the optical input power to an appropriate level, it may be necessary to
attenuate the optical signal.
CAUTION.
To avoid damaging the optical input of the sampling optical, to
maintain the levels within performance range, and to avoid clipping, attenuate
optical signals to less than 5 mW average power or 10 mW peak power at the
wavelength with highest relative responsivity.
80C03 modules can have deteriorated response for signals larger than 200
m

and the vertical response will eventually saturate for levels approaching 1 mW.
