(30) Repeat (29) above for each frequency displayed through 30 MHz.
(31) Press the CLEAR REF WBND soft key on the ac measurement standard. The
TI wideband output should nominally be 10 mV, 1 kHz. If TI displayed value is not 10.0000 mV,
use output adjustment knob to enter this value. When this is completed, the Error
indication should indicate 0.0 ppm.
(32) When the ac measurement standard settles to a reading, press the SET REF
soft key. (This is the 10 mV reference value from which all 10 mV frequencies will be
compared.)
(33) Press ENTER pushbutton, the frequency will advance to the next value.
(34) Adjust the TI output adjustment knob to bring the ac measurement standard
error display to indicate 0 PPM (10 PPM), then press ENTER pushbutton.
(35) Repeat (34) above for each frequency displayed through 30 MHz. Only the 10 MHz,
20 MHz, and 30 MHz points are adjusted.
(36) Ensure that rear panel CALIBRATION NORMAL/ENABLE switch is in the
ENABLE position. Store the values by pressing the STORE VALUES soft key.
(37) Press the DONE WITH CAL soft key.
(38) When TI display returns to normal, set rear panel CALIBRATION NORMAL/
ENABLE switch to NORMAL.
(39) Press RESET pushbutton.
