Error: Aihwa data akapa nokuti kutapurirana	Chiratidzo: The counter values ​​of Data triggered uye ACK triggered in MAC TX Statistics hazvina kuwedzera. Solution: Set Data Source ku PN Data. Neimwe nzira, set Data Source ku UDP uye ita shuwa kuti iwe unoshandisa yekunze application kupa data kune UDP port yakagadziriswa nemazvo sezvakatsanangurwa mune yapfuura.
Error: MAC TX vanofunga the pakati as busy	Chiratidzo: Iyo MAC Statistics kukosha kwe Data Zvakakonzerwa uye nhanganyaya waonekwa, chikamu che MAC TX Statistics uye MAC RX Statistics, maererano, haina kuwedzera. Solution: Tarisa maitiro e curve current mu RF Input Simba graph. Seta iyo CCA Energy Kuonekwa Chikumbaridzo [dBm] kutonga kune kukosha kwakakwirira kudarika kukosha kushoma kweiyi curve.
Error: Send zvimwe data mapaketi than the MAC anogona Provide ku the PHY	Chiratidzo: The PN Data Packet Size uye PN Packets Per Chepiri vanowedzera. Nekudaro, iyo inowanikwa throughput haina kuwedzera. Solution: Sarudza yepamusoro MCS kukosha uye yakakwirira Subcarrier Format.
Error: zvakaipa RF ports	Chiratidzo: The RX Simba Spectrum hairatidze curve yakafanana neye TX Simba Spectrum pane chimwe chiteshi. Solution:

	Simbisa kuti une tambo kana antennas akabatana kune RF ports iyo yawakagadzirisa se TX RF Port uye RX RF Port.
Error: MAC kero mismatch	Chiratidzo: PaChiteshi B, hapana ACK packet transmission inokonzereswa (chikamu che MAC TX Statistics) uye RX throughput iri zero. Solution: Tarisa izvozvo Mudziyo MAC Kero yeChiteshi B inoenderana ne Destination MAC Kero yeChiteshi A. YeRF Loopback modhi, ese ari maviri Mudziyo MAC Kero uye Destination MAC Kero inofanira kuva nekero yakafanana, semuenzanisoample 46:6F:4B:75:6D:61.

Solution: Seta iyo Reference Clock kuPXI_CLK kana REF IN/ClkIn. ·          YePXI_CLK: Referensi inotorwa kubva kuPXI chassis. ·          REF IN/ClkIn: Referensi inotorwa kubva paClkIn port yeNI-5791.
TX Error Rates vari Poshi in RF Loopback or Baseband Loopback kushanda modes	Chiratidzo: Chiteshi chimwechete chinoshandiswa uko maitiro ekushanda akagadzirirwa RF Loopback or Baseband Loopback mode. Iyo graphical chiratidzo cheTX Kukanganisa Mateti inoratidza 1. Solution: Hunhu uhu hunotarisirwa. Iwo ACK mapaketi akarasika apo MAC TX iri kuvamirira; iyo DCF yenyika muchina paFPGA yeMAC inodzivirira izvi kana iri RF loopback kana Baseband Loopback modes. Naizvozvo, iyo MAC TX inogara ichishuma kutapurirana kwakundikana. Nekudaro, iyo yakashumwa TX packet kukanganisa mwero uye iyo TX block kukanganisa rate mazero.
