| Can my Rigol dg1022Z counter be defective ? |

Hi everybody, I'm playing with the fisrt time with the counter of my DG1022. I dont know if it's me but it's really hard to use. For exemple. I setup a simple square waveform from ch1 and enter it in the counter with a coax. 1 Mhz. 2v peak. No offset. I check the output signal on scope.... very clean 0 to 2v 50% duty square wave. To be able to read anything I must set the trigger sense to 95%, level to 0 and coupling is DC. The gate time change only the accuracy. If I change trigger sens to 85%... result jump all over the place If I rise trigger lever to only 100mv... nothing If I lower the frequency to 100khz or 1Khz same result. If I probe with my dm3068 (On Freq as well), it is showing me the right frequency. And this is just one exemple. Is it me ? Or it's very hard use. It's pratically useless. I looked on other thread but nobody is talking about it. It's why I think it is maybe defective ? Thank you Yannick |

Have you tried changing it to a sine wave? Square waves have a lot of harmonics, your counter might be sensitive enough to be confused by them. |

Yes of course, sine wave 1vpp gave me the same thing. If I rise to 2Vpp I can lover the trigger sens to 75%. As well with a sinewave I chossing ac coupling instead DC but anyway I have the same problem in both. It's like my signal is detected very dim or fadeor too low ? Yannick |

Yannick --- End quote --- I had a DG1022 back in 2016. I had problems with the counter as well. The thread is linked below. Mostly it wasn't accurate even with an external GPSDO reference. I reported it to Rigol and they worked a deal for me to return it and get a DG1032Z plus a few $$. I just don't think the counter in those DG1022s are any good at all. https://www.eevblog.com/forum/testgear/rigol-dg1022a-function-gen-frequency-counter-function/msg926368/#msg926368 |

Yes I read your thread. I think I have something similar. I have the new model but I do not know if the internal hardware is updated or better. If I look my reading, I don't think so. |
