3 PRELIMINARY O PERATIONS:
3.1 Review and become familiar with the entire procedure before beginning Calibration Process.
WARNING
Unless otherwise designated, and prior to beginning the Calibration Process,
ensure that all test equipment voltage and/or current outputs are set to zero (0)
or turned off, where applicable. Ensure that all equipment switches are set to
the proper position before making connections or applying power.
3.2 The Opt 001 TI has a high stability time base. Connect a jumper cable from the 10 MHz OVEN OUTPUT to
the EXT REF IN Connector for proper operation of the Opt 001.
4
Page 7
T.O. 33K3-4-2587-1
3.3 The Opt 002 TI has a high voltage output capability of 4 mV to 40 V p-p.
3.4 Connect TI and all test equipment to the appropriate power source, set POWER switches to ON, and allow a
warm-up period as required by manufacturer. Ensure that a TI with an Opt 001 T im e Base has been connected to
power source for a minimum of 72 hours.
3.5 The Std TI an d Opt 001 TI both h a ve a Frequency Accuracy of ±5.0 X 10
-6
of setting. The frequency stability
is not calibrated due to the time requirements in checking the drift rate of the oscillators. The drift rate for the
standard T I i s per year and can not be divided by 365 for a per day specification. The drift err or associated with the
oscillator will reflect in the frequency accuracy. If the frequency accuracy in paragraph 4.1 is out of tolerance, the
TI will have to be adjusted in accordance with the maintenance T.O.
