Review Summary For : PreciseRf DDS-1
Reviews: 1MSRP: 125.50
The DDS-1 dual directional coupler measures forward and reflected power of a device in a 50 ohm environment. It is more precise than a simple SWR meter since the reflected and forward power may be observed directly on an oscilloscope.

Well built Accurate Time Owned: 0 to 3 months.
I purchased the DDS-1 to sample the transmit output of my station. The coupling value is -30dB which reduces the power level by 1000, making it ideal for monitoring with a scope or lower range power meter. It also has a reflected port to monitor reflections from the antenna.

The DDS-1 is quality built and accurate over it's operating range. It works well with my scope to display the signal quality and PEP power output from my AL80B.

I also found the application notes written by Roger Stenbock on their web site very informative and helpful.
