AWG2005 Service Manual
2Ć5
To check the fuse, remove the fuse holder on the rear panel. Refer to FigĆ
ure 2Ć2 for the location of the fuse holder. To remove the fuse holder, turn it
counterĆclockwise with a screwdriver while pushing it in. Then remove the
fuse from the fuse holder.
Consider the following information when you power on or power off the
AWG2005 or when external power loss occurs.
PowerĆon Cycle
At powerĆon, the startĆup diagnostics check the AWG2005 operation. The
startĆup diagnostics take about 30 seconds. If all diagnostic items complete
without error, the AWG2005 displays PASS on the screen and then changes
to the SETUP menu.
If the diagnostics detect an error, the AWG2005 displays FAIL and the error
code. To exit the diagnostics menu, press any key; then the system displays
the SETUP menu. See section 6, Maintenance, for information on diagnosĆ
tics and fault isolation.
NOTE
If the ambient temperature goes outside the specified operating
temperature range, an error occurs during the diagnostics at powĆ
erĆon. If this happens, power off the AWG2005 and wait until the
chassis temperature is appropriate; then switch the power on
again.
PowerĆoff Cycle
CAUTION
To prevent loss of internally stored adjustment constants, DO NOT
power off the AWG2005 when doing the internal calibration deĆ
scribed in section 5, Adjustment Procedures.
Wait for the AWG2005 to finish the operation when doing internal calibration
or saving waveform or sequence files. Improper powerĆoff or unexpected
loss of power to the AWG2005 can result in the corruption of data stored in
nonvolatile memory.
