I just bought a 5B10N on the auction site that looked unusual. It has a toggle switch in the upper right corner of the front panel labeled "L vs R (BLANKING)" and it appears (from the images included in the listing) to have a factory mod called "Mod 711C", but I can't seem to find any documentation about such a modification on TekWiki. Does anybody know anything about this modification and what it does?

I have posted two images of the item (images from the listing, since I have not received the item yet) in the album /g/TekScopes/album?id=270601

I found just this on page 78 in Tektronix_Catalog_1991.pdf?

710R? -? XY/YT switching of center compartment signal711C? -? add control on 5B10N for switch in MOD 710R

Great idea; it takes space, though, if you plan to use battery cells; helpful for LED-LED solution, can be done easier off site...

So it looks like 710R is a mod to the mainframe. I wonder where (or if) I can find a service document describing these mods. I have a scope and time base with Mod 509C, which is not mentioned in the catalog, but the catalog specifies that the list of mods is partial.

I guess I'm cool with having a curio that doesn't work with any of my current scopes.

Hi Jeff,

I just semi-randomly found this:



which includes slightly more information:

Mod 710R: X-Y operation, right Vertical compartment switchable from Vertical to Horizontal operation. For use with standard amplifier plug-ins. Requires 5B10N Mod 711C.

Mod 711C: X-Y operation plus control of unblanking. One switch position allows operation of time base as unblanking generator. See 5100 Series, Mod 710R.

(manually transcribed by sleepy proofreader)

That same 1991 catalog page 78 mentions an app note that may or may not be relevant: "Simultaneous display of two independent X-Y signal pairs" / "5111/5A14N/5A15N/5A18N. Dual X-Y techniques, engine analysis." / order no. 52-AX-4114
