| Considering a new Rigol DHO924 vs. Siglent SDS120X-E model - Any Bug stoppers? |

@Daniel - the 54600 should work fine for watching your RF signals at all HF bands (considering its 100MHz BW). See my shots in the "54600A thread". Your "VFO above 2MHz bounces around" - that could be easily caused by the construction of your VFO. Here you have to provide more info (ie in the RF, Microwave, Ham Radio section). |

However, the 2-channel SDS800X HD scopes do not include a Ext trigger input. Why did Siglent omit this? So, I may need to go with 4-channel after all. --- End quote --- Those hams are saying that for only three reasons: 1) Their old boat anchor CRE only has two channels, so therefore it is enough. 2) They never touched anything modern electronics, not even a simple Arduino. 3) Their old boat anchor CRE can not do digital anyway. You want 4 channels because it is needed to do protocol decodes. If you ever have a simple microcontroller project and need to figure out why the SPI communication is failing, you need this. Even if you only want to do HAM stuff, unless you only want to work on restoring ancient radios, realise that radios all come with microcontrollers and digital internals these days. Especially all the kits that you can build. I am going to recommend the SDS804XHD and 0, 1 or 2x Siglent PP215 200MHz probes. This combination is cheaper than SDS814XHD and gets you 200 MHz probes instead of 100 MHz probes. You can wait to buy the probes until you need them. Remember that sometimes you will connect directly to the scope using a coax cable instead of probes and get the full bandwidth that way. Just make sure to have a through 50 ohm terminator for this purpose. |

We get all our Siglent gear (11 instruments) from Saelig, including the new 814X HD. Their Siglent shipment arrived Friday 3/8 and they shipped out the same day which we received Monday 3/11. Best, |

Baldurn, No. The ham who mentioned he only needed 2 channels uses a Siglent SDS1202X-E scope as many other hams do. But this 2-channel scope also has Ext trigger input as well. The 800 series does not. I was actually considering a SDS1000X-E series scope until I discovered the SDS800X HD series was being released to the West... But you are correct about this ham not using microcontrollers. But later, I will mentor him on them since he has been mentoring me on many homebrewing topics. Last year, I built a VFO using a Arduino Nano, Si53531A clock synth IC, rotary encoder, and a i2c LCD Display, but I already knew Arduino since it was microcontrollers that got me into electronics in the first place. Like iMo suggested, I will move my discussion of the ham radio stuff and measuring a VFO with an oscilloscope to the appropriate forums. Thanks everyone for your replies. I think I beat this topic to death. |
