    Test and Measurement equipment sales statistics.

    Hi All, where can one find statistics for TM equipment turnaround worldwide? I'm most interested in general instruments like DMM's, oscilloscopes and also RF instruments.

    Decreased current consumption after change of PCB-supplier.

    I'm quite confident concerning the components since the BOM is written as MacGyver suggests. There are a couple of "improved versions" that draws less current, but the total of that is less than 1mA. The board is by the way a direct convertion thing workning @2.45GHz. One thing I forgot to...

    Decreased current consumption after change of PCB-supplier.

    Thanks all for your replies! I measured the thickness of the two types of PCB and they differ with ~2,5mil. The one with lower I_supply is thinner (33.7mil). So I guess the next step is trying to put a test strip on the PCB for impedance measurements and write a bit stricter specs.

    Decreased current consumption after change of PCB-supplier.

    Any ideas what can cause a decrease in supply current of ~10mA (from 54 to 45mA @5VDC) after changing supplier for the PCB? The board is of 2 layer FR4, used in a RF unit module of size 10x10cm. All components are from the same batches as before, the only difference is as mentioned a new...
