EEVblog #159 – Oscilloscope Trigger Holdoff Tutorial
Posted on March 30th, 2011 24 commentsOne of the more obscure controls on an oscilloscope is the Trigger Holdoff control. A dedicated control on most high end analog oscilloscopes, and a main menu option in modern digital scopes, yet often poorly understood. What does it do and how does it work?

EEVblog #70 – Turn your Rigol DS1052E Oscilloscope into a 100MHz DS1102E (Hack)
Posted on March 31st, 2010 71 commentsThe ingenious EEVblog viewers have finally cracked the Rigol DS1052E Oscilloscope. All you need is a serial port cable and you can turn your 50MHz DS1052E into the 100MHz DS1102E.
Dave shows you step-by-step how easy it is, and that it does actually work.Rigol caught with their pants down AGAIN!
NOTE: There have been a couple of reports of units failing when this mod is attempted. The cause is unknown at this stage, but the exact sequence of serial commands keys appears to be IMPORTANT. You CAN’T hit backspace or ENTER etc, follow the instructions precisely, key-by-key. The vast majority have had success though.
As with all hacks, do this mod at your own risk.UPDATE: This mod no longer works with firmware 2.04 and above. You have to downgrade the firmware first. See the UPDATE VIDEO.

Posted on July 19th, 2009 20 commentsRigol caught with their pants down! An issue with the Rigol DS1052E Oscilloscope.
Or perhaps it’s Analog Devices caught out?
(correction – there are only 2 PLL’s in the model FPGA used in the Rigol)
