Amin nasab,
Either you are paid to praise this semi-finished product, or you don't know what such a device must measure. All its measured values are not correct. They are far from accurate. Increasing the font size and what you are looking for are irrelevant, until what is important is fixed, which is accurately measured data for MER, BER, C/N, Power, signal quality and strength. Only if they manage to solve it, which I doubt, let them increase the numbers and letters.
