As we continue to work our way through our archive of photos, we run across some that are a bit out of the ordinary.  They may be humorous or unique but they stand out from the other photos. We will post new photos here monthly with the previous photos in the slideshow.

This 1949 photo shows Dick Rhiger's bench at Hawthorne during the 517 development. The 517 achieved a performance of 50 MHz and was introduced in 1951. This oscilloscope did not utilize plug-ins and required a separate chassis for the power supply.  More information can be found on our High Speed Oscilloscope and the Type 517 page.
