Hello Group:

I started a collection of Tektronix gear but have developed an interest in HP's assortment of spectrum analyzers. The 141T seems to offer the biggest variety and seems to be readily available on eBay. I'm interested in general comments about these instruments. Are they servicable, are parts generally available in generic form? Any recommendations?
Thanks for your comments.

Hello George,

I started a collection of Tektronix gear but have developed an interest in HP's assortment of spectrum analyzers. The 141T seems to offer the biggest variety and seems to be readily available on eBay. I'm interested in general comments about these instruments. Are they servicable, are parts generally available in generic form? Any recommendations?

Well, I have a similar disease than you (check my WEB pages for proofs ;-)! )

In last years, I have got the following HP-141T gear:

*Mainframes:

HP-141A (storage; old round tube)
HP-140T
HP-140T (another one)

*Plug-ins:

RF
HP-8553L
HP-8553B
HP-8554B
HP-8555A (unworking :-( )
HP-8556A
IF
HP-8552B
HP-8552B (another one)
HP-8552B (just another ;-) !)
HP-8552B (unworking)

*Accessories:
HP-8443A tracking generator (for the 8553B)
HP-8445A tracking preselector (for the 8555A; untested)

In order to complete my setup, I am missing an HP-8444A and a working HP-8555A (or repair the one I own)

I have fixed myself some items. All three mainframes had power supply problems (mostly related to drifted or opened resistors!). So first thing I recommend is to check power supply voltages. And about plugins, a couple 8552Bs had intermittent problems. I am trying to fix the 8555A but, at the moment, lack of proper test equipment.

I would say all is serviceable, as there are lots of plugins in the market (and it is lot easier for you in the USA!). And equipment is very good for amateur and semi-professional use. So, IMHO, go for it!

Regards,

JOSE

PS: I have most of the Service Manuals, if you need any.

Hello Jose,
Thank you my friend for your response. I find your comments to be very helpful. People like you make the world a much better place to live. I would like to be able to ask you questions in the future with your permission. How do you use your equipment from day to day? Are you interested in radio or other electronics? I will learn more by looking carefully at the web sites that you showed me. I have a fair collection of Tektronix 7000 mainframes and about half of the plugins.

I would like to see photos of your collection if you have them and I will let you know as my collection of 141T starts to grow. Thank you for the encouragement.
