![]() Similar feature barriers are found on Rigol’s new reigning entry-level scope, the DS1054Z, which ships with protocol analyzation modules (among others) that are enabled only for the first 70 hours of scope operation, requiring an additional payment to unlock them. Tektronix has gotten in on this action as well, shipping modules like I2C, CAN, and LIN analyzation on the scope but requiring a hardware key to unlock (these were discovered to have a horribly insecure unlock method). The model shipped with 50 MHz bandwidth but it was discovered that a simple hack turned it into the DS1102E 100 MHz scope. ![]() The Rigol DS1052E was hugely popular on hacker benches because of it’s very approachable price tag. More famously, oscilloscopes have been notorious for having crippled features. ![]() Most recently, we saw a Casio calculator which has the same features as its bigger sibling hidden within the firmware, only to be exposed by a buffer overflow bug (or the lead from a pencil if you prefer a hardware hack). There are numerous examples of hardware which has latent features waiting to be unlocked by software.
