Power on and verify instrument operation

8
The following steps assume the unit is connected as shown in the verification
setup.
NOTE.
Note: The generator is internally temperature compensated for timing and
output level continuously and automatically. Internal timing calibration will also
take place whenever the frequency is set (either manually or through remote
programming). Setting the frequency (or resetting the frequency to its current
value) is recommended after an initial 15-minute warm-up, or if a significant
change in ambient temperature has occurred during operation.
