| Conversion of 500MHz TDS744A to 1GHz TDS784A |
| << < (21/24) > >> |
| nctnico:
You can attach some switches and just try every combination. Perhaps you need a different combination. It is also possible that a monochrome display (I assume the TDS540C has a monochrome display) isn't supported so there is no known model number for your configuration. |

Thanks nctnico. I will need a few days to try this as time tied up these days. The TDS580C published with the FW5.2 as stated in the tek document, so maybe the FW5.0 doesn't have the ID code for TDS580C. But anyway, I will have a try. |

Here is a plot that shows the frequency response of my Tek744A-784A. The device triggers cleanly up to over 1.5GHz, the signal also looks quite good, but the frequency response is already absolutely in the basement. The -3dBm is pretty close to 1GHz. The device is not calibrated. First Picture shows 1.5GHz in ET-Sampling, last Pikture shows 1.5GHz in Real-Time-Sampling. |

Has anybody tried TDS520C or 724C upgrade? |
