AN2719 Freescale Semiconductor / Motorola, AN2719 Datasheet - Page 14

• Manufacturer Part Number: AN2719
• Description: A Transmitter Using Tango3 (Step-by-step Design for ISM Bands)
• Manufacturer: Freescale Semiconductor / Motorola

Measurements
Carrier Frequency
The carrier frequency is measured at several voltages, while the Tango3 RF Module is transmitting a
continuous wave in OOK mode.
FSK Deviation
The FSK deviation is computed after measuring the frequency during transmission of a 1 and a 0.
