b&k television analyst model 1077b. Does it have a use purpose on my bench?

[Sealtest]

Hey all, I was wondering about if this particular unit had much of a use in a test bench that already has a few color dot and bar generators. Every time I clean out a TV repair shop I end up with another one of these units. Currently I have a stack of three on a shelf along with a 1065 analyzer. All have not been tested which is why I ask this question.

I guess it can do test patterns while my generators can only do crosshatch, dots, bars, etc. But is there a reason to pull these units out and use one?
