3-6 INTERNAL TIME BASE

AGING RATETEST

(Optional)

The following test can be used to verify that the 682XXB/683XXB

10 MHz time base is within its aging specification.The instrument de-

rives its frequency accuracy from an internal 100 MHz crystal oscilla-

tor standard.(With Option 16 installed, frequency accuracy is derived

from an internal high-stability 10 MHz crystal oscillator.)An inherent

characteristic of crystal oscillators is the effect of crystal aging within

the first few days to weeks of operation.Typically, the crystal oscilla-

tor’s frequency increases slightly at first,then settles to a relatively

constant value for the rest of its life.The 682XXB/683XXB reference

oscillator aging is specified as <2x10–8 parts per day (<5x10–10 with

Option 16).

NOTES

Do not confuse crystal aging with other short term

frequency instabilties; i.e., noise and temperature. The

internal time base of the instrument may not achieve its

specified aging rate before the specified warm-up time of

7 to 30 days has elasped;therefore, this performance test is

optional.

Forgreatest absolute frequency accuracy, allow the 682XXB/683XXB

to warm up until its RF output frequency has stabilized (usually 7 to

30 days).Once stabilized, the change in reference oscillator frequency

should remain within the aging rate if;(1) the time base oven is not al-

lowed to cool,(2) the instrument orientation with respect to the earth’s

magnetic field is maintained,(3) the instrument does not sustain any

mechanical shock,and (4) ambient temperature is held constant. This

test should be performed upon receipt of the instrument and again af-

ter a period of several days to weeks to fully qualify the aging rate.

Test Setup Connect the 682XXB/683XXB rear panel 10 MHz

REF OUT to the Frequency Reference front panel

input connector labeled 10 MHz when directed to do

so during the test procedure.
