(1) INT/EXT switch (rear panel) to INT.
(2) CW/FM switch (rear panel) to CW (model 5342A only).
(3) ACQ TIME/FAST, MED, SLOW switch (rear panel) to MED (model 5343A
only).
(4) SAMPLE RATE control fully ccw.
(5) Frequency range switch 10 Hz - 500 MHz/500 MHz - 18 GHz (10 Hz - 500
MHz/500 MHz - 26.5 GHz for model 5343A) to 10 Hz - 500 MHz.
(6) 50Ω Ω - 1 MΩ Ω switch to 50Ω Ω .
(7) STBY/LINE/ON switch to ON.
If TI has been disconnected from line source for more than 24
hours, allow at least 24 hours for warmup and stabilization.

5343A)
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. 2) for minimum difference indication on frequency
difference meter. Record frequency difference meter indication.
