The NRP-Z91 is a USB Power meter with a diode head.

notes

• The driver can only be used if the program NRPView, 1.0.27 and above, from R & S is installed. When installing the program make sure that you install all the items. if you do not do this, some dll's will not be copied.
• Setting the resolution higher will make the measurement slower because the power meter is taking more samples and perform an average over the samples. this is done dynamically depending on the power measured.
