Instructions for Operation
Before servicing the AWG2005, read the following operating instructions.
These instructions are at the level appropriate for servicing the AWG2005.
The user manual contains complete operator instructions.
In addition, section 4, Performance Verification, includes instructions for
making the frontĆpanel settings required to check AWG2005 characteristics.
To powerĆon the AWG2005, follow these steps:
1. Set the PRINCIPAL POWER SWITCH (on the back of the AWG2005) to
the ON position. This switch is the main power switch; it routes power to
the standby circuit in the AWG2005.
2. Then, press the ON/STBY (standby) switch on the front (lowerĆleft corĆ
ner) of the AWG2005. This switch applies power to the remaining circuits
of the AWG2005. Allow at least 20 minutes for the AWG2005 to warm up.
WARNING
To avoid personal shock hazard, turn off both the ON/STBY switch
and the PRINCIPAL POWER SWITCH before servicing. The PRINCIĆ
PAL POWER SWITCH on the rear panel is the true power disconĆ
nect switch. The ON/STBY (standby) switch simply toggles
operation on and off. When connected to a power source and when
the PRINCIPAL POWER SWITCH is on, the internal power supplies
and much of the other circuitry of the AWG2005 remain energized
regardless of the setting of the ON/STBY switch.
To avoid personal shock hazard, set the PRINCIPAL POWER
SWITCH off before connecting or disconnecting the line cord to or
from the power source.
At powerĆon, the AWG2005 performs internal startĆup diagnostics. These
diagnostics check internal circuit function and report any failures. In addiĆ
tion, you can initiate internal diagnostics; these diagnostics differ from the
startĆup diagnostics in that they do more extensive memory checking.
The AWG2005 also contains internal calibration routines, which check
internal circuit function and adjust calibration constants. Run these calibraĆ
tion routines whenever the AWG2005 undergoes a temperature change. For
