S2439D Microwave Power Meter

Overview Specifications Ordering Resources

The S2439D microwave power meter can be equipped with different types of USB power sensors to achieve accurate measurement of average power and peak power; it can connect up to four power sensors simultaneously for high-efficiency multichannel measurement; through the function keys and touchscreen on the front panel, fast power measurement can be realized in either numerical or waveform display mode.

S2439D microwave power meter is a good substitute of Keysight N1911A / N1912A / N1913A / N1914A.
