Various Measurement Applications Power Measurement Functions

Average power

Digital mobile communication systems use modulation patterns that can handle signals with large amplitude variations.

Therefore, we have included an average power calculation function that allows power measurement of signals with amplitude variations.

Multiple Markers

Up to six markers can be set up on a single screen, and a corresponding marker can be assigned to any frequency.

The multi-tag function automatically detects peaks and displays a list of frequencies sorted by level or frequency.

The U3661 allows channels to be set for communication systems in major countries.

Most communication systems utilize the FDMA (Frequency Division Multiple Access) method.

When observing signals with the U3661. each carrier band to be measured can be registered in the built-in table as a user channel.

This makes it possible to call the center frequency by the channel number, thus improving efficiency.

Channel numbers from 1 to 99 can be registered, and two tables are provided. 

For TV broadcast waves, frequencies can be preset according to the VHF, UHF, CATV BS and CS band names of major countries.

If the CMDA option (OPT 60) is added to the U3661.

the CDMA transmission characteristics specified in the IS-95 and J-STD-008 standards can be measured in a single operation.
