    Thanks for the test.
    Quite adequate behavior for 1.25 Gs.
    Rigol DS1202z-e behaves in a similar way, only it starts somewhere from 400 MHz.

    It's great to know DHO924S can reach to 500Mhz practically (maybe suitable for me to do some 433Mhz RF test). According to the chip on board, it can reach 800Mhz maximumly without doube, said by EEVblog. Can you test it upto 800Mhz?

    • @LiraLab
      @LiraLab  7 หลายเดือนก่อน +1

      I will do it for 800MHz on the DHO804, I do not have the dho924s in the lab anymore. I believe that using the FFT it might be able to reach that. For 433MHz it's easy. You'll see it in time domain.

    Tudo de bom! Obs: após o limite é ilusão.

      Serve ao menos para teste de presença do sinal e ver a forma de onda. Mas a medida da amplitude será incorreta.

    E possível montar um rf com arduino que gere 100 gigaherts

    • @LiraLab
      @LiraLab  9 หลายเดือนก่อน

      Você pode utilizar um sintetizador que gera 100GHz e controlar ele através do arduino. Seria o melhor desempenho. Outra opção seria vc utilizar um sintetizador de clock de frequência mais baixa com alta potência e usar o 10º harmônico, também controlado via SPI ou UART do arduino. O segredo é vc achar um sintetizador externo ao arduino que precisa de uma programação SPI, I2C ou UART.

    Comprei recentemente um osciloscópio OWON HDS2202S como meu primeiro osciloscópio. Estou esperando chegar. Você já testou ele?

    • @LiraLab
      @LiraLab  8 หลายเดือนก่อน

      Nunca usei equipamentos OWON. Então não posso afirmar.

    Qual é o melhor na sua categoria?

    • @LiraLab
      @LiraLab  8 หลายเดือนก่อน +1

      Na categoria com analisador lógico e gerador de sinal, este equipamento é o melhor da categoria. Na categoria abaixo dele, sem o analisador lógico, o DHO804 é o melhor custo benefício.

    la banda è a -3b , tutto il resto è inutile

      No. Se non si interrompe bruscamente a 3dB, puoi ancora vedere il segnale. L'ampiezza non è corretta, ma è possibile vedere il segnale. È meglio che non vederlo.
