Hi,
I have a fully working 7L5 with Option 25 and L1 input module. It works fine, only for some reason the decimal point in the central frequency readout is displaced one digit. No other issues whatsoever.
Certainly not expecting to get for it the fantasy asking prices you see on eBay, a reasonable offer will do.
It's in Warsaw, Poland. Let me know if you would like me to quote you shipping.
Cheers

Yes, it's the dot frequency readout on the top right corner. A frequency of 500 KHz reads as 50.00 (decimal point displaced one position to the left) where it should be 500.0 . However a frequency of 50 KHz reads correctly as 50.0
In short, when jumping from 3 significant figures to 4, the decimal point is displaced one position to the left.

Greetings.... please look at the settings at the bottom of the oscilloscope trace. I am using the -40 dbV 500KHz output from the 7L5 as a reference. I would like to compare my 7L5 output to your 7L5 output with the same identical input and reference settings. Please set up your 7L5 accordingly and post picture of output. I am thinking the decimal "error" could be an artifact and there is nothing wrong with your 7L5. Perhaps if it works properly you will want to keep it? Thank you

Here it is.
See how the decimal point in the dot frequency is displaced one position to the left, reading 50.00 instead of 500.0; I just noticed as well that the dB/div readout also has a glitch, it should read 10dB/div where it actually reads 1 dB/div (looks as if the zero digit is just missing). The 10dB pushbutton is properly illuminated though, as you will see from the pictures.
Both issues seem to affect the readout part only, as the analyzer itself and the front end both work normally.

Also..... do you have another Tek mainframe to plug the 7L5 into? Or do you have access to another? I am using a 7704 with good success. I also have a Tek 7834 storage mainframe and my 7L5 doesnt work properly in that storage mainframe. I am thinking that your decimal point problem has to do with the fact that we both are experiencing problems with 7L5 and storage mainframes .... try your 7L5 in a non storage Tek mainframe
