    Default Ophir meter question.....

    Does anyone know where to get hold of information on model DG power meter? I need the impedence and Po values for the thermopile output....or a range of what these type of meter will be able to accept { input signal value}. Has single BNC coupler for input.....I have not been able to stir any info on these.
    Thanks in advance...

    The source TEC is a LOW impedance then only a FEW ohms max, BUT ITS A VOLTAGE SOURCE. They put a 5-10K ohm pot in as the adjustable attenuator. Most are set up for .01V per watt or similar.
