Tektronix Oscilloscopes 7904, 2467B, 2465B at 1GHz

The images to follow show a 1 GHz sine wave (amplitude not changed during the testing) on the following Tektronix oscilloscopes:

Tektronix 7904 with 7A24 vertical (400 MHz) and 7B92A horizontal

Tektronix 2467B (400 MHz scope)

Tektronix 2465B (400 MHz scope)

 

 

 

 

 

I have checked the bandwidth of the both the 2465B and 2467B used here, and they meet the 400MHz requirement at -3db (using a Tektronix SG504 with leveling head).  The bandwidth of the 7904 mainframe + 7A24 vertical plug-in used in this test is about 450 MHz (-3db), but it remains at almost that level out to > 600 MHz.  At 1 GHz I can still easily get 175 mV of signal on the screen of the 7904 + 7A24 where the two newer scopes can only manage  25 mV or less.
