Hi all,
Greetings and a very good Morning to all of you.
I have a question on the calibration of power sensors.
I require some suggestions.
What are the standards normally required?
I see from the certificates given out by Agilent..that they use power splitter,a vna, 3 power sensors of the same model , a cal kit , reflection test set , dual channel power meter and a signal generator.
I deduce that they are using the splitter and then via comparison method to end up with the cal factor of the power sensors.
The power sensor in mention is the HP8481A.
I wish i can have some clarifications on these matters..
My questions are:-
1) Do we have to use software to have this calibration done? or can we perform it manually? I trust the best method would be using the software?
2) If we wish to calibrate other power sensors..the E series,the N series or the USB series(eeprom based), can it be done using the OLD power sensors/meters such as the HP438A and the HP848x series as standards?
If we perform the cal by the comparison method, we should have a standard(working and reference sensor) which must be more accurate that the UUT ,true?
3) Are there any freeware depicting how the calibration is done?
Any softwares that can be used to measure the cal factor uncertainty?
Appreciate the help and suggestion.
