Tool/software:
Is there a problem with "SmartRF Studio 7"?
The frequency deviation with respect to the set frequency does not match.
Desired date of response: Friday, October 4
SmartRF Studio 7 is used to look at the frequency deviation in the 429 [MHz] band.
The relationship between each frequency and the frequency deviation in the prototype board is as follows.
Transmission frequency setting: 429.2500 [MHz] Transmission frequency: 429.250742 [MHz] Frequency deviation: 1.728596389 [ppm]
Transmission frequency setting: 429.5000 [MHz] Transmission frequency: 429.500544 [MHz] Frequency deviation: 1.266589057 [ppm]
Transmit frequency setting: 429.7375 [MHz] Transmission frequency: 429.73716 [MHz] Frequency deviation: -0.791180662600387 [ppm]
The relationship between each frequency and the frequency deviation on the evaluation board is as follows.
Transmission frequency setting: 429.2500 [MHz] Transmission frequency: 429.249532 [MHz] Frequency deviation: -1.09027373328393 [ppm]
Transmission frequency setting: 429.5000 [MHz] Transmission frequency: 429.499324 [MHz] Frequency deviation: -1.573923166 [ppm]
Transmit frequency setting: 429.7375 [MHz] Transmission frequency: 429.735994 [MHz] Frequency deviation: -3.504464935 [ppm]
Essentially, no matter which frequency is set, the frequency deviation should show the same value.
Thank you.
