Hi Robert:

I don't think the SA/TG will completely error out, but may fail certain normalizations if you do not have the appropriate flatness.

I know of a vendor who may be able to help you with making the cable assemblies you require. When I get home next week, I will pass his contact information along.

Also, I seem to remember an article (maybe in QST), which discussed how to make these cables on your own if you are so inclined.

Thanks for the information, I agree with both of your assessments. It was easy to find the Cables in a flex format so I went out and bought some on day one. Now that I read your posts I know it won't work and my dilemma is that I have no idea where to find the Semi Rigid versions. I am going to do some searching but I have a feeling I am going to need a lot of luck on my side to make this happen. If the unit will error out it makes little sense for me to proceed further until I locate these cables so at this point I am going to mark out the plate for cutting and drilling based on Jims info and then when I know where to get the needed cables I will start the cutting and drilling.

If anybody has any of these cables and is willing to sell them please let me know or if you have any ideas on a source that might sell them the info would be greatly appreciated.

Hello Robert:



With regard to the rigid coax cable used to connect the TG to the front
panel, I think you are going to want to use this. While at low frequency
other types of cable may work fine, when you get into microwave you may run
into a problem with the TG Gain Flatness Normalization. If the output of the
TG is off by more than +/-3dBm (This is from memory so double check), it
will show up as a fault when you first attempt to normalize.

how do I install it?







Hi Jim

Thank you so much for the reply. I do have a VR BW board in that cavity and
I received the TG with no cables at all, I will have to figure out how to
obtain the needed parts and where to source them.
I was wondering if flexible cables with SMA and Type N will work or does it
have to be the rigid stuff? I obtained a copy of the 2712 SV Manual and am
going to look through it tonight to try and get a better idea of what I am
dealing with, I want to thank you for your post, it certainly clarified
things for me, I hope I am up to the task of doing this Job as I must admit
I am a bit worried about messing up my 2710 it has been absolutely a
pleasure to use over the years and is in fantastic condition.

Let me ask you Jim is there any chance of having my proverbial cake and
eating it too?
I mean could I leave in the VR BW board and run cables to the Back of the
unit and put the TG in a separate enclosure, kind of like a DIY 2707? I am
just wondering if anybody has ever done that, I would imagine that it might
not be practical but I just wanted to get your opinion.

Anyway Jim I am going to take out the VR BW board and see what I am dealing
with. If you have any suggestions please post them, and thanks so much for
your help.

Hi Robert -
The TG mounts in the cavity on the left side of the analyzer. This also is

the same cavity which houses the Variable Resolution BW board. You can only
use one or the other, not both. It wasn't clear whether you have the VR BW
board or not.

There are two semi-rigid cables that will need to be made. One routes the

RF to the front panel and has an SMA on one end and a Type N on the other.
The other routes the 2nd LO (2 GHz) to the TG. Did you receive these cables?
The ribbon cable will plug into the main power supply board to provide the
interface. in fact, I just remembered that one end of the ribbon cable is
crimped to a IDC connector that is *soldered* to the power supply board. The
other end uses at typical IDC connector that will plug into the TG. The 2712
(not 2710) service manual has a block diagram that will aide in making the
necessary connections. This manual is down loadable from the Tek.com site
and will be a better reference for what you are wanting to do. You will have
some work to do to get your TG up and running. Take your time and it will go
smoothly.

Good luck.

I posted about a month ago about searching for an internal tracking

generator for my 2710 SA and I finally found one from an old Tektronix
dealer.

Now I have this unit with Id No 119-3889-07 it's in a golden colored all

metal case with 3 female SMA connectors and a 10 pin 2 row IDC connector.

Luckily I found several old Mobo serial connectors that are the right

size but only use 9 of the 10 pins so I removed the wire and made a 10 wire
straight pin to pin cable from the connector ends.

Now I open up my 2710 to locate grounds and power pins on this IDC

connector and have a WTF moment. Where the Heck does this thing go!! I
remember a side section that was free but the unit won't fit and all the
card slots are used up! Plus its just too big, so I have no clue how this
fits into a 2710.

I can find nothing on the net about this Option 04 tracking generator,

it's not even listed in the 2710 service manual but I have seen several 2710
sold with Tracking Gens built in and the guy who sold it to me told me it
works with the 2710 Arggggh....

Anybody have any idea what I should do next? I can't even locate the 10

pin connector that it supposed to plug into much less fit the unit into my
2710. Man I hope I did not waste all that money, I am having serious regrets
now. Sorry if this comes of as a Crazy Rant but I should have done my
homework before making this purchase, I am upset with myself.
