Measuring SAT, TV, CATV and Optical Signals

►
All individual or multiple ends of optical fibres or ends that have not
been capped off, which carry a power classed as hazard class 1, should
be covered individually or collectively when not being worked on. Only
covers or covering materials with sufficient optical energy screening
capability for the respective wavelengths may be employed for this
purpose. Do not expose sharp ends.
►
When using fibre optic test leads, the optical energy source should be
the last device to be connected and the first to be disconnected.
►
Never make unauthorised modifications to fibre-optic cable systems or
their associated devices.
►
Renew any damaged warning instruction labels, and where warning
instruction labels are missing attach new ones.
►
Always use test equipment of the lowest class necessary that can practi-
cably be used for the work intended. Do not use test equipment that is of
a higher class than the hazard class applicable to the location.

Performing Optical Measurements
The Optical Measurment is only possible on Vertical Low Band.
1. Connect the signal meter to the optical source to be measured via an optical fibre.
2. Press
VOL CONFIG
to check whether the RF input (
RF IN
) is set to
OPTICAL
in the
configuration menu.
If the RF input (
RF IN
) is not set to
OPTICAL
, tap the value and select
OPTICAL
.
➯
The optical input converts the injected signal into an RF signal before starting the
measurement.
3. In the main menu, tap on the icon
OPTIC
to open the optical measuring function.
➯
The following view is displayed:

4. Tap
WAVELENGTH
(
①
) to select the value of the selected wavelength to be measured
by the signal meter between 130 nm, 1490 nm and 1550 nm.
5. Press
STORE
to save the delivered power level delivered by the signal meter (
