e. Set LINE switch to ON. If TI has been disconnected from power more than 24
hours, allow at least 24 hours for warmup and stabilization.
8. Time Base Stability - Option 001 Only
a. Performance Check
(1) Connect time/frequency workstation OUTPUT 1 MHz to frequency difference
meter REF INPUT.
(2) Connect TI 10 MHz OUTPUT (rear panel) to frequency difference meter SIG
INPUT.
(3) Adjust FREQ ADJ (fig. 1) for minimum difference indication on frequency
difference meter. Record frequency difference meter indication.
