Fig. 7-15 Modulation oscillator frequency test set-up
(1) Connect the test equipment as shown in Fig. 7-15.
(2) On the UUT set source A to:
[MOD ON/OFF] (To enable modulation source)
[FM Mod Freq] 10 Hz
(3) Record the frequency measured by the counter against each of the modulation oscillator
frequencies shown in Table 7-49.
(4
) Repeat (2) to (3) for source B and, if Option 1 is fitted, source C.
