Re: USB Power Probe Calibration software
|
1.) There are some commercial Power Sensor Calibration packages out there that support the USB Sensors ( PS/CAL, Surecal)? but those are very expensive ??? i am not aware of any free software that allows for a user to access/edit the calibration factors
2.) There are commands on the E Series Power sensors that allow access to the Sensor EEPROM but i am not sure if this is the case for the USB Sensors as well
??? you can try DIAG:SENS:EEPROM ? X with X being the number of bytes to read and see if you get a reading but even if you do than it will take quite a bit of work ? ? to figure out the calibration factors
3.) if your sensor readings are "way off "? than it is very likely that your sensor is damaged ,? try readings at different power levels (+10, -10, -20, -40dBm and see if they are all off by the same magnitude ,? wide dynamic range sensors have two diode detectors and a range switch , depending on the power level either the high or the low range detector is used ,? if only one range is off than this is a indication that one of the detectors is faulty , if both are than you either have a damaged attenuator ( on the H Series sensors ) or a corrupted EEPROM ! ?

I have acquired an in-calibration U8485A opt 200 USB thermocouple power sensor and a way out of certified calibration U2001H USB diode power sensor. I also have the latest N1918A Power Panel (free version) and the latest full BenchVue (on trial for 3 more weeks).
Does anyone know about the (probable) software that can read (and write) the calibration data to these probes? Is a "secret' option in one of the packages I have? If not, how can I get it?
Thanks for your help. BobD
