DANGER! — Removing the cover for repair, maintenance and adjustment must be
done by qualified and trained personnel only, who are fully aware of the haz
ards involved.
The warranty commitments are rendered void if unauthorized access to the interior of the instru
ment has taken place during the warranty period.
Grounding
Grounding faults in the line voltage supply will make any instrument connected to it dan
gerous. Before connecting any unit to the power line, you must make sure that the protective
ground functions correctly. Only then can a unit be connected to the power line and only by
using a three-wire line cord. No other method of grounding is permitted. Extension cords must
always have a protective ground conductor.
Caution: If a unit is moved from a cold to a warm environment, condensation
may cause a shock hazard. Ensure, therefore, that the grounding requirements
are strictly met.
DANGER! — Never interrupt the grounding cord. Any interruption of the pro
tective ground connection inside or outside the instrument or disconnection of the
protective ground terminal is likely to make the instrument dangerous.
Electrical Connections
For a graphic representation of all electrical connections, see "Rear Panel" on page 29 and
"Front Panel" on page 26.
Using any of the
communication interfaces
is not required for GSG to operate in a basic
mode. The same applies to the outputs for 1PPS and 10 MHz , as well as the inputs EXT REF
FREQ and EXT TRIG : Their usage is not compulsory for basic operation.
The minimum electrical configuration for any test layout requires only the
power cord
and an
RF antenna cable —or an actual GNSS antenna—to connect the GSG unit to your receiver-
under-test (using the front panel RF connector, see "Front Panel" on page 26.)
