Wiki Typo


 

Dear Erik,?

the device looks promising in the Wiki description. For most ham operators it should be a helpful device.

Only minus for me: as far as I see it, for useful oscillator characterization (PLL performance) it is not usable: -100dBc a few kHz from the carrier is not in the specification.
But for harmonics (-70dB should be kept to prove -60dB)? and spurious search it would suit, as far as I see it.
The question will be: Can you can scan the 1st harmonics of e.g. 50MHz and the next harmonics 100, 150, 200, 250 300 MHz with one sweep and what will be the detection limit? Or would the user have to scan the first harmonics, memorize the level, change the range, scan the 2nd .....

To the typo: in the technical Specs "Input frequency range from 240MHz to 9600MHz" has a "0" too much.

Karsten,

Thanks for the feedback. Typo corrected and phase noise spec added.?
Phase noise is -90dBc/Hz at 100kHz offset and -115dBc/Hz at 1MHz offset. This is a consequence of the balance between cost and functionality.
In this post?/g/tinysa/message/5? you can see a picture of a full 350MHz scan showing all the harmonics (and additional spurs) of a 30MHz signal.
As the VBW is bigger then the RBW given the 290 display points the tinySA inserts additional steps and takes the maximum of these steps for the display points.?
