Applying and Interrupting Power
Consider the following information when you power on or power off the
instrument, or when power is interrupted due to an external power failure.
CAUTION. You can not 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 temperatu-
res, before turning on the instrument again.
Upon power on, the waveform generator runs a power-on self check. If it passes,
the AWG500 displays a Pass status message and a prompt to press any key to
continue. If it fails, the AWG500 displays a diagnostic log that identifies the
area(s) that failed and a prompt to press any key to continue. Refer to Section 6,
Maintenance, for information on diagnostics and fault isolation.
CAUTION. DO NOT power off the waveform generator when either running a
signal path compensation or when doing any of the adjustments described in
Section 5, Adjustment Procedures. To do so might result in the loss of internally
stored adjustment constants.
In general, do not power off the instrument when doing operations that affect the
data stored in the memory. Wait for the instrument to finish the operation when
doing adjustments, saving waveforms, or saving setups.
Improper power off or unexpected loss of power to the AWG500 can result in
calibration data corruptions on the hard disk.
