ATTEN AT5005 Spectrum Analyzer?

(1/5) > >>

Mechatrommer:
googling around for spectrum analyzer, i found ATTEN AT5005 Spectrum Analyzer 150K - 500MHz USD430 in ebay http://cgi.ebay.com.my/ATTEN-AT5005-Spectrum-Analyzer-150-KHz-500-MHz-/270655175572?pt=LH_DefaultDomain_0&hash=item3f044e3b94. anyone with knowledge of this item? i need something for my 433MHz RF design/tuning project.

alm:
No experience, but what's the point of a 500MHz specan for 433MHz? You can't even see the first overtone, so you might as well a frequency counter if you just want to determine the fundamental. The price does seem very low for spectrum analyzer, even used ones are usually much more expensive.

Mechatrommer:
whats the overtone? any good reference? i want to maximize the rf transmitting power, so when making pcb for the 433mhz rf, i can see if my trace is too long, my inductors and capacitors value are not right etc, so i can make adjustment to the circuit to avoid to drift too much from 433mhz, is the atten 5005 is not enough for this? should i consider harmonics freq as well? or this overtone? sorry if this sounds too newbie, as this is my first attempt to design such a thing. so i'm looking for appropriate device/tester. from what i know/search, its the spectrum analyzer, and this atten, is something closest to affordability, even its still on the high side... for my budget.

i have another search, portable protek 3201 Sale $1,320.00 http://www.testequipmentdepot.com/protek/analyzers/3201.htm?gclid=CIWsjNqZrKYCFcV66wod0wJ8MA

Mechatrommer:
the 1ghz version of atten is AT5011 US $797.88 http://cgi.ebay.com.my/ATTEN-AT5011-A-spectrum-analyzer-Tracking-Generator-1G-/300404563383?pt=BI_Oscilloscopes&hash=item45f181ddb7
