- Page 2 GW Instek GOS-6030 Reverse Engineered Service Manual Introduction A few years ago the opportunity came along to purchase a number of GW-Instek GOS-6000 series oscilloscopes, all with faults/damage. A deal was then agreed, and for better or worse I became the owner of 16 6XXX oscilloscopes of varying specifications.

- Page 5 Description The GOS-6030 oscilloscope is the base model from a small range with varying bandwidths, capabilities and features (6031, 6051 etc.), the third digit indicates the bandwidth in MHz, and the last digit the specification level. My guess is that most, if not all of the internal circuit boards are common across the range (which I will confirm as I investigate the scopes in more depth), with a few extra boards installed, or varying build levels on the common modules to extend the specifications.
- Page 6 Fault/Servicing Notes • Be careful of sharp edges on the chassis. It will bite! • With any brightness issues or dim/weak traces, first check the CRT board for dry joints • Access to the X input circuits can be tricky. Desoldering the screening plate at the two rear corners, and then sliding the plate to the rear will give access to the components.
