Oscilloscope, 60 MHz, 2 channels The Tektronix 2224 is similar to the 2232, the differences being some jumpers on the CPU board to tell the firmware it is a 2224 rather than a 2232 there are three front panel buttons on the 2232 which have no corresponding actuators or holes on the 2224 the 2224 is a 60 MHz scope; the 2232 is 100 MHz. When working on a 2224, the 2232 manual can be used for most purposes.
