Re: HP8407A Network Analyzer... opinions?
Jose V. Gavila
Hello my friends,
Well, I finally did it, as it was an eBay offer (so it had an ending date yesterday night), was located locally (in Valencia, Spain, where this evening F1 world champion Alonso will present McLaren-Mercedes new car ;-) ) and price was about right; so I have bought a working 8407A, with the 8412A display and a 8601A sweeper for the equivalent of US$284. Please, note that I am in Spain, where HP equipment is by far less available than in other markets. So, well, I know it has not accessories (in fact, it has not even BNC-BNC cables!), but it was tested by the seller (I know him personally) and it works (there were also pictures of it in the auction). 110MHz is not too high, but to start playing with network analyzers (I have never had a _working_ one at home; I have an 8754A but currently is not working), it should be enough. If I later find the need for higher frequencies or functionality, will look for other options. But by now I will stay with the 8407A :-)!. Once I have it at home I will let you know how it works (let's hope it really does!) Thanks for your help; don't think I have not listened to your opinions, which have been really valuable.

Re: 141T storage failure

I guess that the week-end stopped other guruhs from responding. Since Richard's mail the following has happened: checked ground lead for -12.6V heater supply, also connected earth side to ground with lead. Even connected a 12V bulb across it result: ground connection is OK. checked all other crimped connectors at their respective connection point result: all seem OK checked 6.3V heater supply, put 6V bulb across it: all OK checked connections to pots on store panel: all OK checked all leads coming from CRT, including those coming from the top to their corresponding connections on respective boards: all OK Could someone please confirm that the colour coding of the wiring to the neck of the CRT is as follows, looking from the front of the equipent towards the back: (9),(5),(943),(9),(5),(4) This is not obvious from the manual. Would appreciate suggestions / advice, where to go from here. Chris ----- Original Message -----

The black lead inner conductor was broken at the push-on connector to the HV board. These connectors are known for poor crimping which fails after several pushon /pulloff events.

Re: HP8407A Network Analyzer... opinions?
J Forster
Ok, thanks for the info!. What is in the 'accessory kit'?
It has probes, adapters, and such things as I remember. >You might want to look at an 8505A if you have a choice. Could I get an 8505A for less than US$300 ??? Regards, JOSE Maybe. You would have to shop carefully and get the parts one at a time. A full 8505A has 4 boxes. You MUST have two, the RF Section and the Display. The Storage Normalizer and S Parameter are options. If you don't have the S Parameter, you may need a Reflection-Transmission Test Set. It depends somewhat on your intended use. The 8505A goes to 1.8 GHz. If you are going to probe IFs, the 8407 might be a better choice. IMO, the 8413 meter is near useless except for CW measurements. The expensive parts are often the special cables required to interconnect the boxes. They've been discussed on-list fairly recently. FWIW, -John |

HP8407A Network Analyzer... opinions?
J Forster
Hello!
I have the chance to get a nice HP8601A + HP8407A setup. Please, could you comment about this set (performance, price, experiences, ...)? Thanks!!! Best regards, JOSE It's a pretty decent Vector ANA, if a bit old. The 8601A is a nice little sweeper. You will need the accessory kit too. My only real criticism is that you have to change display units to change to Smith Chart from rectilinear displays (unless you have the accessory box). OTOH, the same displays work in the 8410 system also. You might want to look at an 8505A if you have a choice. -John |

Re: HP8568B CRT replacement question LCD?
It was mentioned that there is an LCD replacement available for a tired CRT
used in the 8568 and 8566 series. I use an external Tektronix X-Y-Z display which is OK but is there an LCD X-Y-Z device available for a reasonable price, or a way to adapt a computer display to work with the three outputs provided by the display unit? Since storage and graticle lines are provided by the display unit, it shouldn't be too difficult. Stuart K6YAZ Los Angeles, CA |
