Got it...
Not a problem for me in a most of points. This will be not the only SA in the shack, and not even second one.
I have HP8920A with SA/TG and R&S CMU200 (both bought faulty and restored), so I have no problems with signal generator, power meter and SA coverage while working at workbench. E7495 looks like good extension of TG capability and SWR measurement over 1 GHz, plus TDR functionality. And it is portable, that is a big plus.
Yes, I know about typical problems with screen, and prepared to recharge batteries and store them separately if unit is not used for some time. And price is relatively good, comparable with current eBay offers if overseas shipping is taken into account.
I think the device is worth the roughly $300 shipped I paid for it. $1000 shipped (what I see on ebay now), not so much. Mine did not come with any attenuator or calibration kits or power sensors. Just the unit, the bag, two cables.
It's worth keeping in mind that the 375MHz minimum TG output imposes a hard limitation on the efficacy of the TDR function. If the cable is lossy or if it's short enough (or both) then you just get garbage output.
I remember trying to debug some bnc balun-coax- bnc balun wire (which was used for CCTV cameras, which have an expected bandwidth of 6MHz or so) and being unable to make good measurements for this reason. It's an extreme example, but it's worth keeping in mind that the 375MHz lower bandwidth on this instrument is a limitation that has multiple impacts.
Also, yes, I think the GPS receiver in this unit is (relatively speaking) not good. I originally hoped to use it as a GPSDO but even with wide open skies it loses lock somewhat randomly and if there are even minor obstructions you will get maybe 2 satellites intermittently.
I have also not gotten any other of the features to work to decode e.g. CDMA over air or directly out of a phone or actual base station or something. I don't really understand how it works or if my setups were correct, but to me all of those applications are essentially useless.
Lastly: I am not 100% sure but I think if the unit you are looking at has the two ports populated (RF 1 and RF2) then it should be software hackable to get the TG enabled. I have not ever seen a unit without the ports populated.
