Teardown of a Wavetek 395 Arbitrary Waveform Generator

Another extensive teardown by Kerry D. Wong, this time of an early 1990s-era waveform generator by Wavetek. Because if the product manual doesn’t contain any images whatsoever of the unit, the only way to find out is to open it up! Those ceramic cylinders are pretty intriguing, as is that giant lithium battery manufactured by Matsushita Electronic.

I picked up a Wavetek 395 arbitrary waveform generator on eBay a few weeks ago. Wavetek 395 is a single channel, 12-bit resolution DDS AWG with a maximum clock frequency of 100 MHz. While the operation manual is readily available, I could not find the service manual anywhere. So I was curious to see the construction inside. In this post, I will show you some of the teardown pictures. If you want to see a video of the teardown along with some analysis, you scroll towards the end of this post.
