Power analyzers are available in different accuracy classes, to allow the user to choose the right tool for the job at hand. After all, not all applications require maximum precision; often lower resolution and frequency range are sufficient.
Unfortunately, not all measuring applications exhibit this distinction. It is very well possible, for instance, to have need for different frequency ranges and accuracy levels at different points in the same measurement configuration. This is why the LMG600 offers three different channel types, which can be combined in the same chassis without problems to ensure that you always have a measuring device tailored to your needs for your particular application.
No need to accept trade-offs in accuracy or take a sledgehammer to crack a nut, if a lower priced solution could have served your purposes equally well.
