Standby
Operation
Whenever the signal generator is not being used it
should be left connected to the power source and
placed in standby. This keeps the internal time base
frequency reference at operating temperature.
On the front panel, press LINE to switch the
MG369XB from OPERATE (green LED on) to
STANDBY (orange LED on). (Hold the LINE key
down for at least ½ second to prevent power-off of
the unit.)
NOTE
During standby operation, the fan runs con-
tinuously.
Warmup Time
From Standby–When placing the MG369XB in op-
eration from standby, allow 30 minutes warmup to
assure stable operation.
From a Cold Start (0°C)–The signal generator re-
quires approximately 120 hours (5 days) of warm up
to achieve specified frequency stability with aging.
NOTE
Instruments disconnected from ac power for
more than 72 hours require 30 days to return to
specified aging.

Installation Rack Mounting Kit Installation
MG369XB OM 2-9
Before installing the MG369XB in its operating environ-
ment, ensure that all airflow passages at the sides and rear
of the instrument are clear. This is of particular importance
whenever the unit is being rack-mounted.
Keep the cooling fan filters clean so that the ventilation
holes are not obstructed. A blocked fan filter can cause the
instrument to overheat and shut down.
