Concept of global, group, and channel parameters

Deﬁnition of a group

With a multiphase power analyzer there is often a requirement to link together

measurement channels. This is known as grouping. Within a group, one

channel will act as the frequency source a nd reference for all other channels

in the group. Grouping is commonly used in applications such as three phase

motor measurements. Channels 1 and 2 can be grouped together to allow for

the m easurement of the input power, where Channels 3 and 4 could be grouped

together to measure the output power. For more information on applying grouping

to channels, see the Wiring section of The Menu System chapter. (See page 47,

Wiring.)

Global, group, and channel

settings

The PA3000 has many different settings that affect both the appearance of the

results and the actual results. To make the instrument easier to operate, settings

might have an effect on one or more parameters. Depe nding on the parameter, the

inﬂuence or use of it might be on a global level, a per-group level or a per-channel

level. The split for parameters that have an effect on measurements and results

is deﬁned below.

Global settings

Global settings affect all measurements. The following settings are global:

lanking (See page 59, Blanking.)

Averaging (See page 59, Averaging.)

Update rate (See page 60, Update rate.)

Autozero (See page 60, Autozero.)

Global settings will appear under the System Conﬁguration menu.

Groups settings

Per-group settings affect every channel in a group. The settings affected are:

Measurements (See page 36, Measurements.)

Measurement conﬁguration(Seepage38,Measur ement Conﬁguration menu.)

Mode (See page 42, Modes.)

Wiring (See page 47, Wiring.)

Ranges (See page 50, Ranging.)

Shunt selection (See page 51, Shunts.)
