AWG710 Service Manual

NOTE. If the air flow is restricted and the internal temperature of the AWG710
Arbitrary Waveform Generator exceeds the proper operating temperature range,
the instrument temporarily shuts down to protect the internal modules from
overheating. To prevent temporary shutdown of the AWG710 Arbitrary Waveform
Generator do not restrict air flow through the chassis.
If the AWG710 Arbitrary Waveform Generator shuts down unexpectedly,
improve the ventilation around the waveform generator and wait a few minutes to
allow it to cool down; then switch the power on again.
You cannot power on the instrument when the ambient temperature exceeds the
instrument temperature operation range. Wait until the instrument cools down, or
the ambient temperature decreases to valid operating temperatures, before
turning on the instrument again.
Verify that the fuse is the proper type and rating.
Remove the fuse from the fuse holder on the rear panel and check the fuse. To
remove the fuse, turn it counterclockwise with a screwdriver while pressing in.
Table 2–3 lists the two fuse types and ratings.
WARNING. To avoid electrical shock, be sure that the power cord is disconnected
from the socket before checking the line fuse.
