a. Performance Check
(1) Program time/frequency workstation for a 1 MHz output and connect to
frequency difference meter REF INPUT.
(2) Connect TI rear panel 10MHz OUT 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.
