| Siglent SSA3000 plus or Rigol RSA3000 - which one is "best buy" |
| (1/4) > >> |
| SK:
Hello Guys, the last weeks I read a lot of the threads concerning both devices but I am still not shure which one I should buy. :-// As it seems the SSA3021x plus for about € 1800,- can be (slightly) easier "improved :-X" to a 3.2 GHz VNA (SVA1032) without heavy risks... ....on the other hand, the RSA3015N (N!) (?) for about €2500,- can be "updated ;)" to 3.2GHz "realtime" (RSA5032) or even 6.5 GHz. (RSA5065) (the cheepest Sigent Realtime starts with 3.2GHZ at 4800,-) ...but: wether the 6.5 GHz are possible or not seems to be dependend from the hardware-revision => is this still possible with actually delivered devices? So even if there are only 3.2GHz - the Rigol delivers Realtime for "only" 700,- add-on (comparing 2500,- with 1800,-) What about the other aspects of the device: Does anybody know both devices and can make a shortly objective comparison? The Siglent-SSA-Series seems to be 7 to 8 years in market know - the Rigol RSA is about 5 years newer !? Thank You very much for your thougts... :-+ SK |

Welcome to the forum. Do not confuse the earlier release SSA3000X models with the later SSA3000X Plus models. They are different HW and SW platforms and X Plus are more highly featured. Touch, mouse and webserver support and a better EMI option are in X Plus models which for a few $ more makes a no-brainer to get the X Plus and for these reasons we no longer stock the older X models. |

I got the Siglent SSA 3032X-R which I managed to upgrade to 3075X-R with all options enabled. It is only €3995 so I am unsure where you got the other price. I choose this model to get the real time option, but I have found I rarely use that. If I had to buy again I might just go for a cheap SDR to do the RT work. I am however very happy with having 7.5 GHz bandwidth and I also love that VNA is build in. If this is your first SA I might also suggest starting out with a TinySA Ultra to learn what your needs really are. It is just €150 and goes all the way to 6 GHz. Combine that with a NanoVNA and a SDR (for RT). Could get you going for less than €400 total. |

Don't expect 6.5GHz. If you really need RT then it's a no-brainer in financial terms. |

Hi All I have a Rigol RSA3015N. Awesome machine. The real-time function is very good and you wonder why it didn't come out sooner. VNA too. I also have the original version of the SSA3000. A good analyser but not a patch on the Rigol. I have measured both with a phase noise analyser. The Rigol is down around -155 dbc at 10 kHz, way better compared to about 140 for the Siglent. I would love to hack the Rigol but not found anything. Regards Drew VK4ZXI. |
