This is a duplicate of an interesting discussion going on among the WLAN Advisory Board membership.

rick, you should tell me what tool you use for spectrum analysis

that Tektronix unit was pretty cool as far as spec ans go. Not very portable, but symbol decoding and constellation views live for sub $5k is outstanding.

@sclements: did you test all the various software options, or just the base Textronix unit? I’m thinking of getting one just for the constellation features. It would be a great way to test EVM issues LIVE. Your thoughts?

sclements [10:11 AM]
I didn’t have a whole ton of time with it, so it was a ‘guided remote’ tour of the software

[Rick Murphy]

I’m thinking of getting a single unit for the ‘heavy lifting’ analysis, but it’s clearly not WiFi troubleshooting focused – its far more about protocol/radio development

[Rick Murphy]

[10:11]
it’ll never replace your Cognio 😉

Cognio :+1:
Troy, are you looking for Wi-Fi Only SpecAn or wide spectrum? For Wi-Fi only (in order of cost/features) AirMagnet Spectrum XT, MetaGeek WiSpy DBx, and Nuts for Nets has one called RF Explorer 6G Combo that looks interesting but I haven’t personally tried it. Anyone have experience with that one? For wide spectrum it gets a little deeper.

similar to the Tek but at a better price point

which tektronics model are we talking about? I’ve played with the RSA306 and was very impressed, had some fun analyzing LTE and CDMA/GSM bands with it as well. I’d like to get my hands on a RSA500, anyone have any experience with one?

[4:05]
so i was asking for comments

For full band I’ve always used Anritsu. but I don’t think they have anything that competes with these prices for new equipment. Anritus does have a sale for demo equipment going on now. Here is the link in case that’s of interest to you: http://www.goanritsu.com/demo?utm_source=ASR&utm_medium=EM&utm_campaign=ASR_ASR_16APR_AprilDemo_EM_Demo_MULTI-P_DEMO_OT-03112&cmp_id=Q6UJ9A086ATL&elqTrackId=80B5FC1E75C55250E792A4AD25CC8B0D&elq=0896255b3fe3408289649a014583ada7&elqaid=1920&elqat=1&elqCampaignId=1754

For Cellular I use AirMagnet Spectrum ES.

[Rick Murphy]

sclements [7:59 AM]

@rick, is the ES still around? I thought they killed that off with the netscout thing

[Rick Murphy]

rick [10:01 AM]
Not sure if its still available for purchase but I’ve got mine.

[10:03]
Looks like its in the NetScout linecard still. http://enterprise.netscout.com/content/datasheet-airmagnet-spectrum-es-cellular-spectrum-analyzer Anybody want me to check further?
