finish of the test time period of 24 hours. The aging

 

rate is the difference between the two error read-

 

ings.

 

1. Set up the Frequency Reference as follows:

 

a. Press the ESC key until the MAIN MENU is

 

displayed.

 

b. At the MAIN MENU display, press 1 to select

 

CONFIGURATION.

 

c. At the CONFIGURATION MENU display,

 

press 8 to select MEAS.

 

d. Press the MOD key and use the Up/Down Ar-

 

row keys to get to the menu display:

 

MEASUREMENT = FREQ.

 

e. Press the ENTER key.

 

f. Press the ESC key until the MAIN MENU is

 

displayed.

 

g. At the MAIN MENU display, press 3 to select

 

the REVIEW MENU.

 

h. At the REVIEW MENU display, press 8 to se-

 

lect TFM.

 

2. Connect the 682XXB/683XXB rear panel 10 MHz

 

REF OUT signal to the Frequency Reference front

 

panel 10 MHz input.

 

3. Wait approximately 90 minutes (default setting)

 

until the FMFOM on the Frequency Reference

 

display decreases from 9 to 1. (The default setting

 

is recommended to achieve optimum mease-

 

ments.)

 

The frequency error in the signal under test is

 

displayed in ps/s (Picoseconds/Second). For exam-

 

ple, an error of –644681 ps/s is –644681 ￿ 10–12or

 

–6.44681 ￿ 10–7away from the 10 MHz internal

 

reference of the Frequency Reference.

 

The frequency error display is continuously up-

 

dated as a running 5000-second average. The av-

 

eraging smooths out the short-term instability of

 

the oscillator.
