| Why aren't these combined into the one piece of test equipment ? |

Please excuse my ignorance but ... Why isn't the "SIGLENT SVA1032X 3.2GHz 2-port VNA with Spectrum analysis" combined with the "SIGLENT SSA3032X-R Real-time Spectrum Analyzer 9kHz~3.2GHz" ?? Is it just essentially a marketing exercise ? What can't I do on one machine or the other ? Is there a technical reason why you would not combine the two machines ? (This would be backed up by seeing companies buying the two machines I assume.) Cheers. |

Look here. Basically it shows you that the SVA doesn't have the realtime capability, because it doesn't have the necessary HW. If you are willing to pay the X-R price, I think Siglent can create a "special" SVA for you. Look here where I posted the inside of a SSA X-R. For those that have seen SVA/SSAX+ you can see that the HW is different. --- Quote from: tautech on May 14, 2022, 09:23:45 pm ---Apart from BW all these models have identical SA capability: SSA3000X Plus, SVA1000X and SSA3000X-R. --- End quote --- Well, maybe SSA3075X+ is a X-R inside... ::) The SVA/X+ can't be licensed from 3.2GHz to 7.5GHz. But the X-R can. |

OK. So essentially, the market might get to a point where it would demand the two instruments be combined. Or perhaps we have two legacy product lines that will naturally be combined as technology advances. I think the VNA has a more sensitive front end or lower noise but I could be wrong. Thanks for the replies so far. |

Of course the technology advances will bring the price down. BTW, a few years ago I was asking myself this same question that you did. Off-topic curiosity: A Rigol RSA3015N can be "upgraded" to a RSA5032N and costs only 2.500€, while a Siglent SSA3032X Plus which costs 2.900€ can be converted to a SVA but has no realtime capabilities. |
