TDS1002 Upgrade toTDS1012
The TDS1002 is a 60Mhz, 1G/S 'scope, but the hardware is capable of running up to 100MHz, when it is then badged as a TDS1012. These notes show how I upgraded my 1002 to a 1012. The procedure to upgrade has two main steps, first update the 'scope model number via the RS232 interface, then run it through the factory calibration procedure. It will then operate as a TDS1012. My understanding (but I have no direct experience of other models) is that the same procedure is used for the TDS1000 and TDS2000 series of 'scopes. The first step is relatively easy, the second not so. There are a total of 70 steps to perform, first by inputting various DC voltages, then by applying various RF inputs. It took me several attempts to finally get this all to happen without the 'scope complaining and failing a step, and here are the main take aways: When any one step fails, you have to go right back to the begining and start again. The input impedance of the 'scope varies during some ...
