Hi all, I am measuring the power of two signals (sinusoids) through an RMS calculation, using an TwinRX on a x300 motherboard. In the calibration process (lab conditions, no noise, no interference) I’m trying to obtain a differential power (p1-p2) of 0dB or at least constant at ±0.5dB . One of the channels, RX2, is highly stable with respect to the environment temperature variations, while the other one, RX1, is much less so.
I am aware that this might be a very particular use case, but was wandering if anyone had had this kind of experience or at least knows if there is any documentation/datasheet concerning temperature sensibility of these two components? Best regards, Arjan
