Hi,
I have a question on the voltage measuremnts with multimeter.
I am measuring two output for my IC. These two outputs are the CML signal outputs.When no signal input, the dc output multimeter shows are 4.53 V and 4.45 V, respectively. When there is signal transfering, I also use multimeter to monitor its output common mode voltage, it gives 4.49 V and 4.46 V, respectively which are different with the dc mesuremts results.
Can anyone tell me why this descrepance?
Thanks in advance
