Rigol DS1022C hack brings it up to 100MHz speed


[Andreas Schuler] has been playing around with his Rigol DS1022C digital storage oscilloscope. It’s an older model which can capture samples at up to 25MHz, but [Andreas] claims to have quadrupled that using a service menu hack. His technique changes the settings to use the DS1022C at 100Mhz.

Usually a hack like this includes some test measurements that confirm the hardware is actually sampling at the higher rate, and is not just claiming that it has the ability to do so. We’d love to hear from you in the comments if you’ve got this piece of bench hardware and decided to try it for yourself. His method enters in a sequence of buttons from the system info menu. If done correctly this will add a service menu option that wasn’t there before. A bit of navigation leads you to the screen seen above, where you can change the model number to DS1102C. This is the more robust 100MHz cousin of the 1022.

If you think you’ve seen this hack before it’s probably because the Rigol 1052E was previously pulled to 100MHz with a firmware hack.

50MHz to 100Mhz scope conversion

[Ross] is the proud owner of a 50 MHz Rigol DS1052E oscilloscope. He’d like to have the 100 MHz version but the $400 difference in price puts it out of his reach. After some extensive poking around on the PCB and pouring over datasheets, he managed to reverse engineer the design and upgrade to a 100 MHz version. This is as easy as desoldering one capacitor to deactivate a high-pass filter present in the lesser model of scope, unlocking the faster potential of its bigger brother.
