TDS2CMAX is a bundle with cable and software. Same hardware as TDS2CMA. TDS2CM and TDS2MM will only work on TDS210/220/224 |

Ok, does anybody has TDS2CMA firmware? my PCB board will be available this weekend, and I'm going to find out if TDS2CM and TDS2CMA are based on same hardware and just with different firmware. |

Finally the PCB board arrived, after quickly put everything together, and twist the PLD firmware couple of times, it works finally. The scope identified the module as TDM2MM, it can be TDS2CM with corresponding firmware. As you can see from image, I removed parallel and GPIB port, and changed RS232 to USB port by adding a UART to USB bridge chip. With the module installed, now my TDS210 supports FFT, rising/falling time measurement as well as positive and negative pule width measurement. With the PC tool "TekScope Utility" I can get screen hardcopy, waveform, and measurements on PC, basically this module functions just like a real TDS2MM. I have couple of spare PCBs, I'm going to list them on eBay, not to make money, but to let those who sell TDS2CM with crazy price know that this module can be made with only 1/3 to 1/5 of their listing price, and hopefully they can lower their price to a reasonable range. |

Does anybody has a spared blank module cover? like the picture below? somehow my scope doesn't come with this cover, looks like this cover can hold a PCB, so if I can change the width and height of the PCB board, and cut a square hole on the cover for USB connector, it will fit. |
