i guess they successfully lured TheSignalPath to give a good review on this stuff and he havent look this thing into more details.
Where do I start...
1) You can see the calibration screen and the parameters which can be entered clearly in my video:
youtu.be/LN9PKKdFibo?t=16m23s
i know that (i bought this unit remember?), but its just the mechanical offset length that is user adjustable. fringing effect offset to open standard, which is frequency dependent cannot be set.
2) The manual of the unit clearly states what can be entered:
S11 abides by SOL calibration, in which the three capital letters respectively
represent 3 types of calibrators: short, open and load.
KC951011/KC951012 is the SOL calibrator that we (Kexinshe) produced. Users can
also use other proper calibrators, but keep in mind that the terminal effect of the
chosen calibrators must be small enough since there is no compensation for KC901V
(non-commercial version). KC951011’s nominal electric length is 5.26mm and
KC951012’s one is 0. If a user chooses other standard, he/she needs to input the
value of the actual electric length in the FUNC interface.
meaning that... KC901V cannot be used with any calibration kit, even the most expensive one, if its not following the
"terminal effect of the chosen calibrators must be small enough" criteria, let alone diy cal kit version. and how small is "small"? is anyone's and the KC901V's FW guesses.
I didn't give the unit a "good" review or "bad" review. I showed exactly what it can do and what its limitations are considering its price.
and many more comments as such before that... the only negative side you mentioned iirc is the limitation of SA functionality... but i tell you what, i still agree (and respect) in every aspects of what you said in the video, except you missed the most important limitation of the VNA (its main advertised purpose), ie it cannot user adjustable terminal (fringing capacitance) effect. this make the measurement output of the device is questionable. other expert highlighted that many advises in the manual are nonsensical, and you just highlighted one of it... how small is small the terminal effect? this is non-technical person writing the manual.
This is the second time (that I am aware of) in the past few weeks which you have smeared my work due to your own ignorance and self-entitlement.
except this, you seems to take things more seriously into personal affair. i try to shoot the other people but you seems to take the hit, too bad... the earlier one is one ignorance blaming tektronix due to their ads popping out infront of your video. blaming tektronix is blaming the wrong guy out of ignorance, i just tried to advice him, if "he has to blame" somebody, the video publisher should be more appropriate person to shoot at, but i dont mean you TheSignalPath is rightfully to be blamed, its just he liked to blame anybody. i cannot make counter reply to the post since the thread is locked (due to gender attack etc).
and now the 2nd time is this, i try to shoot deepace, but you take the hit, why? deepace paid you? i got pissed off by their incompetent at support service. even if how good their products are, if they dont bother to reply to their unsatisfied customers, would you still recommend them? who has to be blamed? the person who lure? or the person who got lured (victim)? i dont blame the victim ok. but instead of educating, warn people and look more into this matter seriously, you keep continue mourning how innocent you are and how perfect your reviews are that anybody cannot say negative about it, you only like to hear positive reply, then i guess you have some motive behind all of this, and my respect to you will go down logarithmitically. i'm sorry for the misunderstanding...
Regards...
