Set-up for measuring spectral output of 100W rig. Note the 100W dummy load behind the tinySA |
This is an example of where the availability of a new item adds value to something that's been around a while. The new item is the tinySA - many hams now have one of these small spectrum analyzers/signal generators - and the old item is Elecraft's CP1 bidirectional coupler.
Questions I get whenever I post something related to the tinySA are:
- Can I use it with non-QRP equipment?, and
- How do I measure a transmitter's output to make sure I don't exceed the tinySA's 6dBm (4mW) max input?
I decided to use my tinySA ULTRA to measure the spectral output of my Yaesu FT-891 when operated at full power: 100 watts.
