(nRF52832 and nRF52811) Out of band spurious(323MHz~403MHz)

[Mitsuhiro]

Hi,

When evaluated under the following conditions, there was Out of band spurious@325MHz~403MHz (See the following Results ).

1. Does nRF52832 has spurious(-50dBm~-60dBm) at this band?
2. Does nRF52811 has similar spurious?

Conditions

　DUT: nRF52 DK

    TX power Setting: 0Bm

    Power supply: 3.0 V

Results

    Out of band spurious(325MHz~403MHz):

        -53dBm@325MHz (TX Freq. = 2402MHz)

        -52dBm@363MHz (TX Freq. = 2440MHz)

        -55dBm@403MHz (TX Freq. = 2480MHz)

Hi,

Due to the holiday season in Norway all of our main hardware engineers at tech support are currently out on vacation. They will be back the 2nd week of January and come back to you then.

Best regards,

Marjeris

There are no known spurious coming from the nRF52832 or the nRF52811 in this frequency range. Please make sure you do the measurements in a shielded environment as other signals may affect your measurements.

Sorry. It was a mistake.

The signal was distorted on the spectrum analyzer.

The nRF52832 has no problem!
