Figure 3−14. FSK Output From Transmitter With an External Modulation
Note:
This is FSK modulation with f 1 equal to 915.0 MHz, f 2 equal to 915.10-MHz and 1000-Hz data rate.
The f 1 frequency is the 0 frequency. The f 2 frequency is the 1 frequency.
Perform the FSK modulation output test as described in the previous
section. In this new setup, an external pulse generator is providing the
modulation. The FSK Test button on the chip layout screen does not need
to be pressed to start the FSK test.
