(14) Adjust the TI output adjustment knob to bring the ac measurement standard
error display to indicate 0 PPM (10 PPM); then press ENTER pushbutton.
(15) Repeat (14) above for each frequency displayed through 30 MHz.
(16) Press the CLEAR REF WBND soft key on the ac measurement standard. The
TI wideband output should nominally be 300 mV, 1 kHz. If TI displayed value is not
300.000 mV, use output adjustment knob to enter this value. When this is completed, the
Error indication should indicate 0.0 ppm.
(17) When the ac measurement standard settles to a reading, press the SET REF
soft key. (This is the 300 mV reference value from which all 300 mV frequencies will be
compared.)
(18) Press ENTER pushbutton, the frequency will advance to the next value.
(19) Adjust the TI output adjustment knob to bring the ac measurement standard
Error display to indicate 0 PPM (30 PPM), then press ENTER pushbutton.
(20) Repeat (19) above for each frequency displayed through 30 MHz.
(21) Press the CLEAR REF WBND soft key on the ac measurement standard. The
TI wideband output should nominally be 100 mV, 1 kHz. If TI displayed value is not
100.000 mV, use output adjustment knob to enter this value. When this is completed, the
Error indication should indicate 0.0 ppm.
(22) When the ac measurement standard settles to a reading, press the SET REF
soft key. (This is the 100 mV reference value from which all 100 mV frequencies will be
compared.)
(23) Press ENTER pushbutton; the frequency will advance to the next value.
(24) Adjust the TI output adjustment knob to bring the ac measurement standard
Error display to indicate 0 PPM (10 PPM), then press ENTER pushbutton.
(25) Repeat (24) above for each frequency displayed through 30 MHz. Only the 10
MHz, 20 MHz and 30 MHz points are adjusted.
(26) Press the CLEAR REF WBND soft key on the ac measurement standard. The TI
wideband output should nominally be 30 mV, 1 kHz. If TI displayed value is not 30.0000 mV,
use output adjustment knob to enter this value. When this is completed, the Error
indication should indicate 0.0 ppm.
(27) When the ac measurement standard settles to a reading, press the SET REF
soft key. (This is the 30 mV reference value from which all 30 mV frequencies will be
compared.)
(28) Press ENTER pushbutton; the frequency will advance to the next value.
(29) Adjust the TI output adjustment knob to bring the ac measurement standard
error display to indicate 0 PPM (30 PPM); then press ENTER pushbutton.
