Well it came in, and the first thing I did was run self-test... which worked. But I came back the next day and ran...and it failed self test #3 which was a "signal level" issue. After researching... one of the first things suggested by the make is..... put a full charge on it!!!! And it WAS on the weak side....so I charged it overnight... until the charge light went off. NOW it passes all tests. The maker said that ... in retrospect... he may have made the test comparisons too tight... which would mean that a lagging battery will cause that.
So I got in here and stuck it on my B&K 2040 to read what it puts out. To my surprise.... when I set the attenuator switch on -70 and rolled the RF out control up to put the needle "dead on" 0 dBm (which should put out -70 dBm... the Tiny SA saw -69.9 dBm. Cutting the story short....I still need to run the whole calibration on the output adjustment...as the tracking is not real good. (when you roll down -1 dB should be -71 but the SA reads -70.5. When I roll up 1dB... should be -69 the SA reads -68.3). AND when I MAX the RF out pot the needle doesn't quite reach the end of the scale.
But I do think that this will suffice to get the generator close enough in calibration for what I will be doing....and it certainly better than nothing.
It DOES scan slow (I knew that from reading before) but I like what it does. I know it is no match for a good HP or Rigol but, at $139, and as close as it looks to be, it will be fine. I think I'm going to like it.
