Emissions when scanning on NRF52810

Hi,

I am scanning for BLE devices on nrf52810 using the following code but while scanning I see spurious emission on BLE adv channels seen on spectrum analyzer. Is there a way to stop it?

    // Configure
    uint32_t ram_start = 0;
    uint32_t error_code;

    error_code = nrf_sdh_enable_request();
    error_code = nrf_sdh_ble_default_cfg_set(APP_BLE_CONN_CFG_TAG, &ram_start);
    error_code = nrf_sdh_ble_enable(&ram_start);
    
    // Start Scan
    (void)sd_ble_gap_scan_stop();
    sd_ble_gap_scan_start(&m_scan_params, &m_scan_buffer);
    
    //sleep for 10 seconds and print when seen a specific BLE device
    
    // Stop Scan
    sd_ble_gap_scan_stop();

Thanks

Regards
