The majority of signal amplitude or level measurements made at RF and microwave frequencies are measurements of power rather than voltage. Voltage measuring instruments such as RF millivoltmeters are still in frequent use but are nowadays less common

The presence of a normal mode ac voltage can generate a significant dc offset in a digital multimeter (DMM). We have measured this offset for a range of instruments and find that it is more pronounced in high performance DMM's. This effect is related
