| (1/1) |

Hi, i couldn't resist and bought this powermeter on ebay: https://www.ebay.de/itm/334958415802 However, there's almost no documentation on the internet available. Does anyone know how to read measurement values from the serial port? Or even better, have a manual? It doesn't have much inside - 4 sensors, two MUX's, one SPI ADC and the microcontroller. The microcontroller seems to have the ISP fuse blown, at least i wasn't able to read the firmware the via SPI. Don't have a 44 pin adapter to try parallel programming. The 4 converters are providing a DC voltage equivalent to the measured power, 0V for -30dBm, +2.5 for about 15dBm. All 4 inputs are generating the same voltages, so all channels seem to be ok. It would likely be not to hard to write a custom firmware for this unit, but maybe someone knows how to use them. Thanks! |

Hi, It seems that the powermeter works or worked with the radimation software: https://wiki.radimation.com/wiki/index.php/Chapter_15 https://wiki.radimation.com/wiki/index.php/Schaffner_CPW9670_Channel_1 Have you tried to contact schaffner directly ? |

The thing responds to *IDN? via the serial port and says: --- Code: ---RF Power Meter: Iss 0.0p --- End code --- |
