| R&S SMIQ as a replacement for a general signal generator? |

--- Quote ---and at new prices in excess of $30k I'd say calling it "economy grade" (a term usually reserved for entry level kit like the stuff from Hameg) is quite a stretch. --- End quote --- Back in the 1990s Hewlett Packard classed/marketed the first ESG signal generators as "Economy Signal Generators" and the A and D variants use the same basic frequency plan. So the close in phase noise performance for sig gen frequencies from LF through to lowish VHF frequencies is dire on both A and D versions because of the shared frequency plan. |

Nice discussion I have started (o; Well for sure I know it's not gonna be the Signalhound VSG25A.... Speaking of the Agilent model...can the VSA software control the E4406A and the E4433B at the same time? |
| G0HZU:
Sadly no... The E4433B isn't directly supported and it also uses a different scheme to download IQ data to it via GPIB. So it's a double no in this respect unless someone knows otherwise? Maybe an older version supports it? I'm using the E4406A and the E4433B together as part of a research project so I've created some reasonably powerful Windows based tools to allow me to view/edit/process captured IQ data from the E4406A and it converts the format and sends it to the E4433B for playback. These tools do some specific things unique to my requirements and I'm afraid that I can't give away my software tools for various reasons. Note that I'm not a SW engineer and it really isn't difficult to create apps like this using something like VB anyway :) |

Well I just started recently with C#...and was impressed how easy it is to develop a websocket communication app for Windows phone talking to a Raspberry Pi via Amazon server (o; I'm still not sure which model I should choose...Agilent or R&S....I like both brands....I'm very happy with me new E4406A...but also like R&S...otherwise I wouldn't have two CRTU-RUs and a SMT03 now...kinda weird hobby collecting old equipment for studying and learning RF technology.... And since it's a private hobby I tend more to go for a device with lower price.....but currently most SMIQs on Ebay are listed as "for parts only" with a low price...or Agilent models starting at US$ 2500.... Hmm..speaking of self written software....is there a software API how to directly dump I/Q from a E4406A via socket communication? |

I replied to your other thread. E4433 with UND can be found cheaper in the states and many sellers ship internationally. Why are those E4406 so cheap (well, so to speak)? Limited spec or what? |
