RE: Radiated Emissions > 1GHz
Donald I think you need to look at warranty ,current calibration and the possibility of it having to be repaired. This sounds like an older unit so will it used at one station or will it be moved about? I think it would be hard to get repaired so if it isn't going to be moved about then you probably have a solution. If its a mobile unit then you should probably invest in something a little newer. Just my own thoughts of caution.

The unit is a very reasonably price and would appear to be satisfactory for pre-compliance requirements. Intend to configure the SA with a Low noise 1 GHz - 18 GHz pre-amp and 1-18 GHz horn antenna. Wondering if any one on the forum had any experience with this particular SA and whether or not there are any issue which we should consider or be cautious of.

Donald MCElheran Product Compliance Don: That analyzer should work out OK for pre-compliance testing. However, if you do plan to test all the way to 18 GHz, you might find that the typical double-ridge horn antenna has a rather high antenna factor above about 15 GHz. I stop using my EMCO 3115 at 12 GHz, where I switch over to a home-made pyramidal horn to continue up to 18 GHz. As an example, my EMCO 3115 has an antenna factor of 47.5 dB at 18 GHz, but my pyramidal horn has a factor of 35.7 dB. That 12 dB advantage helps a lot! BTW, remember to put your pre-amp at the antenna output terminal for best performance.

Re: Radiated Emissions > 1GHz
Donald, If you intend to use it under software control, it is not very good. You must do many things manually, including switching ranges. At most you can use software to capture scans and apply cable and antenna factors. Bob Richards. Square D.
