13 Power meter
The power meter measures the total power and
fundamental power of the signal present at the input
terminals to the bandwidth of the instrument (>1MHz).
One of the inputs must be configured as an external shunt
input. The external shunt may be a simple resistor or
dedicated high frequency precision shunts are available as
accessories. Current transformers and clamps may be used
if fitted with a suitable burden resistor. For use at mains
voltages, a mains power adaptor incorporating voltage and
current transformers is available.
The power meter will operate either from its own
generator or, more normally, will use the frequency
measured on channel 1 (usually voltage).
The power meter measures the elementary values:
W
V rms
A rms
V fundamental (in-phase and quadrature)
A fundamental (in-phase and quadrature)
V dc
A dc
V harmonic (in-phase and quadrature)
A harmonic (in-phase and quadrature)
frequency
and derives the following values:
V & A fundamental magnitude
VA (true and fundamental)
power factor (true and fundamental)
fundamental W
harmonic W
phase shift
