Total Power

For spread spectrum signals used in CDMA or wireless LANs, the total power measurement function is essential.

This function consists of two modes: a channel mode for measuring the in-band

power specified in the measurement window, and a total power mode for measuring the total power over the entire measurement span.

1 Hz resolution frequency counter

Simply by adjusting the counter markers according to the spectrum,

the U3661 can display a frequency counter with a minimum resolution of 1 Hz.

This feature is very useful in multicarrier frequency measurements such as mobile radio or CATV systems,

where it is difficult to do so with conventional frequency counters.
