 :I have no objection to replacing the ""Megger"" photograph with something better. To me, better means illustrating something useful about a TDR. 
 :The Megger photo is very poor resolution. It does not illustrate much. 
 :I have some minor problems with the generic TDR. For example, the 6dB loss in the open and short examples (cable attenuation 3dB/100ft) and smearing (dispersion/group delay). I have no problems with the incidental display of a logo. 
 :I have an old Tektronix TDR, but it uses a 25ps risetime step rather than an ersatz impulse.  
 :I have twice reverted the replacement of the Megger with pictures of a Livewire TDR. I removed the Livewire photographs because they just showed a box with logos; the Megger photograph at least included a display of a reflection. 
 :I have received an email from  that shows a WP:COI with Livewire. The email claimed advertising was not intended, acknowledged that other of his/her links had been removed, claimed the newer pictures were offered as updates, and inquired about having both the Megger an Livewire photos coexist. The offered Livewire photographs are not acceptable.
