Hi Teksperts, Is it possible to identify which options are locked within a Tektronix TDS640A from the serial number? I understand that many options are present but 'locked' from access on lower spec models and are unlockable with a hardware/software 'hack'? I am particularly interested in the FFT math function... I am aware that there is often an extra 'sticker' on the rear of the instrument declaring enabled options like (1F floppy drive) etc but is there a database that explains what hidden options are available? Secondly:- Does anyone know if the VGA output displays in colour even if the oscilloscope is shipped with a monochrome screen (and if VGA colour), can the screen be substituted for a colour LCD like the "CRT and shutter" swap previously described in this forum? Thanks Dave |
