*This output level of the standard signal generator (SSG) is indicated as SSG’s open circuit.
When adjusting by automatically, must change the SSG’s level which is depened on adjustment frequencies as shown above.
CONVENIENT: The “RF TRACKING” can be adjusted automatically.
q: Set the Displayed frequency (TL ch.) 30.100 MHz
w: Connect the SSG to the antenna connector and set as:
Level : 0.5 µV* (–113 dBm)
Modulation : 1 kHz
Deviation : ± 3.5 kHz
e: Receiving
r: Push the [BAND] key to start tuning, automatically.
t: Repeat q-r to perform additional frequencies.
