Velund: The Attenuator that came with mine is JFW Model 50FH-040-100-3N 40 dB It is indeed a 100 Watt attenuator. The filter that came with mine is a 1930-1990 MHz band pass filter, so of limited usefulness. Unless you want to spend a lot of time maintaining this unit, I would not recommend it. I cannot see your "local offer" so I do not know it a power sensor is included. They are expensive and easy to break. Wally |

Will it take more time than "maintaining" GF? ;) And no, there is no power sensor head in the offered set, it was sold separately with sensor cable. The only thing I really worry about - is missing option 500. I suspect that it is will need just software hack to enable, but wish to be sure before purchasing. |

I had to modify and re install software to get the GPS to work. The batteries are a problem and the unit needs frequent recharge even at rest. The rubber around the screen creeps and needs to be fixed, You have to disassemble the thing to do this. There is no documentation I can find for schematics to fix any problem. There is poor documentation in general. For example: can you find if the freq gen is software or hardware? I guess not. I really do not remember if it is hardware or not. Even if you have the freq gen it STARTS at 375 MHz no lower freq available. GPS disciplining of the frequency standard is not very good, IMHO. No where near a separate GPSDO Try to read the entire thread to see what problems people have had. Notice the amount of computer code they are talking about. Depending on what you are going to do with it, there are much better choices, especially if you are going to use it for working on HF radios. You are not getting the power sensor so.... So essentially you are getting a spectrum analyzer. Minimum span is 1 KHz which is not bad for a service monitor. I betcha you can get a spectrum analyzer with a tracking generator that meets your needs for whatever the unit is going for. You haven't quoted a price. The only real advantages to the unit that comes to mind is to actually receive weak signals over the air to look for spurious signals and interference, that is if the antenna is included. And some antenna analysis. Screen is pretty also. |

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. |

The only way I was able to update the GPS date was to change the date on a PCMCIA card that contained the entire program for the unit and update the unit. If you have trouble with the GPS I can send you a copy, you need a PCMCIA card though. 64 MB is the one I have. It is pretty simple if you have a card and a computer that can use it. |
