Spectrum Analyzer + PC: Interface & Contact Info

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of operating a spectrum analyzer via a PC or laptop, specifically targeting the frequency range of 100-180 GHz. Participants explore potential interfaces, equipment availability, and the technical challenges associated with such high-frequency measurements.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant inquires about the possibility of interfacing a spectrum analyzer with a PC or laptop.
  • Another suggests Picoscope as a potential solution, noting that many sound recording software packages include spectral analyzers.
  • Several participants question the feasibility of measuring signals in the 100-180 GHz range, with some expressing skepticism about the availability of such equipment.
  • One participant mentions an Agilent unit that operates up to 50 GHz and suggests checking Agilent's website for higher frequency options.
  • Concerns are raised about the high costs associated with spectrum analyzers and related equipment, with estimates of $100,000 or more for top-tier devices.
  • Another participant notes that Agilent has sampling oscilloscopes and real-time scopes that can reach up to 100 GHz and 30 GHz, respectively, but at significant costs.
  • Some participants speculate that the original poster may have meant a lower frequency range (e.g., MHz instead of GHz), suggesting that more affordable options would be available in that case.
  • Discussion includes the mention of harmonic mixers for spectrum analyzers, with references to manufacturers and the high costs associated with these components.
  • Concerns are raised about the original poster's expertise, with suggestions that they may not have sufficient knowledge for such advanced equipment, leading to speculation about their intentions.

Areas of Agreement / Disagreement

Participants express a lack of consensus regarding the existence and accessibility of spectrum analyzers capable of measuring in the 100-180 GHz range. There are competing views on the original poster's knowledge and intentions, with some suggesting they may be inexperienced or a troll.

Contextual Notes

Participants note the rarity and expense of analyzers that can operate in the specified frequency range, indicating that such equipment is typically used in advanced research settings. There is uncertainty regarding the original poster's actual requirements and understanding of the technology.

Hi everyone,
i want to operate spectrum analyzer by pc or laptop. Is there such interface of spectrum analyzer and pc possible? If yes, then how? Tell me the name and contact detail of person who have make such interface..
 
Engineering news on Phys.org
Picoscope.

Most pieces of sound recording software also usually have spectral analysers.
 
What's the frequency range you want to measure?

frequency 100-180 Ghz
 
Does a scope or spectrum analyzer even exist that can analyze a 100-180GHz signal?! I suspect not even close, the top-of-the-line Tektronix and Agilent scopes barely reach 20-50GHz and cost well over $100,000...

I didn't even know people manufactured electronics that operated at those frequencies let alone logic analyzers.

Maybe he meant 100-180 MHz, in which case he can buy any number of units to analyze the signals...
 
What you need is a waveguide harmonic mixer adapter for a spectrum analyzer. Agilent manufactures harmonic mixers up to 325 GHz in various ranges.

VA Diodes makes harmonic mixers up to 1.5 THz

In either case, they are absurdly expensive. Expect to fork out 20K for just the adapter, and 100K for a spectrum analyzer.

Agilent has sampling oscilloscopes that work up to 100 GHz and has recently rolled out real time scopes that work up to 30 GHz, but they cost like 250K. Spectrum analyzers covering 100 GHz have existed for more than 30 years.

I'm not up to speed on what the differences are between a sampling o-scope, real-time o-scope, and spectrum analyzer... Nonetheless, it sounds like a spectrum analyzer may exist for the sort of frequencies the OP is looking for, although possibly not something cheap and easy that he can plug into his computer.

yes, and based on OP's other threads, it sounds like OP is actually working on something advanced without having so much a clue of the basics which leads me to believe the OP is a troll. This kind of equipment can be accessed in graduate schools, in defense contractor and other types of research labs.

Analysers covering that range are extremely rare and extremely expensive (it would be considered a major investment even for a big research institute).
But I agree with what, the OP is probably is troll.
Anyone working with equipment that operates in that frequency range will know how to do something as basic as connecting measurement equipment to a PC( since anyone who needs analyser will presumably already have the source, waveguides/quasioptics etc so we are talking about quite sophisticated and expensive equipment, not something that would be used by a total novice without supervision).

Although I guess it is possible that he really meant kHz (not GHz).,..
