Tektronix 067-0681-01 Pulser

Overview and functional check of the Tektronix 067-0681-01 Tunnel Diode Pulser. This device was used to check the risetime of wide-band oscilloscopes in the 70s and into the 80s. For more information see: https://w140.com/tekwiki/wiki/067-068... I do not have a sufficiently fast 'scope to really check this out.... For the scopes I used here: 60MHz BW - 5.8ns rise 100MHz BW - 3.5ns rise 200MHz BW - 1.75ns rise Compare my results in the video against those figures....
