Question about V2 PLUS4 I can't find answers to


barnc4br 2020/12/22 18:17

I am attempting to learn how to use my new V2.4 PLUS4 and I am running into a lot of missing information that may be helpful to me. I would very much appreciate it if anyone will fill in the blanks, ANY of the blanks.

1. What does RESET and RESET ALL do? What does each reset?

2. What is TRACKING?

3. What is DELTA?

4. Why would I want to set anything other than the default 201 sweep points?

5. What is CW under CFG SWEEP?

6. What is the effect of changing the WINDOW under TRANSFORM?

7. What does APPLY under CALIBRATE do? The only thing I found was it did the same thing as DONE.

8. What does ENHANCED RESPONSE under CALIBRATE do?

9. Which FORMAT(s) of trace does ELECTRICAL DELAY under SCALE apply to? and how is it actually used?

10. What is the ELECTRICAL DELAY range?

11. What is the range for SCALE/DIV?

This is a decent video on the NanoVNAs. It gets pretty technical for the uninitiated.

Are you kidding me? I paid $133. for this instrument and now I must pay $169. to find out the basics of using it.
Not going to happen.

I would like a USER MANUAL not a detail application text book.

The answers to my questions should be in a USER MANUAL.

I will say that while playing with it in an effort to write my own manual, I have answered 2, 3, 4, & partially 9 & 10. questions.
A few still allude me, like the 1, 5, 6, 7, 8, & 11

$169?

Perhaps take a look at the $3 version:

That is the new retail price listed. Then there is tax. If you have a $30.000 unit I am sure it is worth it.

barnc4br 2020/12/24 06:37

thanks David. more my style.
I am amazed no one can tell me specifically what RESET and RESET ALL does.
That is pretty basic, don't ya think?

Be MERRY and stay safe.

thanks David. $3. more my style.

THANK YOU, that lead to a whole new treasure trove of information that will take me years to follow. IMHO, anyone with a VNA should be capable of handling any tech in that, in case anyone else is reading this.

Yes! The sort of thing I would write a pop-up hint for in the Windows
software I write. At a pure GUESS, Reset All => manufacture reset?

David

. What does RESET and RESET ALL do? What does each reset?
reset resets calibration ... reset all also scan area (100 to 900 megs)

2. What is TRACKING?
marker tracks highest or loweat peak

3. What is DELTA?
set two markers and see difference of these two values

4. Why would I want to set anything other than the default 201 sweep points?
low number is higher speed (for coarse tuning)

5. What is CW under CFG SWEEP?
normally the signal on output is switched on and off (in off is switched to internl load ecal) .. if you want to use the device as signal generator that on off is not good ... in cw mode ecal is off and you the set start and szop to same value

6. What is the effect of changing the WINDOW under TRANSFORM? (still trying to figure that out guessing it is similar to rbw)

7. What does APPLY under CALIBRATE do? The only thing I found was it did the same thing as DONE.
apply switches on and off the calibration data

8. What does ENHANCED RESPONSE under CALIBRATE do?
show higher sensitivity then

9. Which FORMAT(s) of trace does ELECTRICAL DELAY under SCALE apply to? and how is it actually used?
delay is to add or substrakt a part of your measure coax (say a double female) to shift your reference plane
you know what reference plane means??

10. What is the ELECTRICAL DELAY range? ... no idea but you normally use short extensions and with the speed of light that will be very low numbers

11. What is the range for SCALE/DIV?
depends on what trace you change the scaling ...
it can be 5 .. or 10 or 20 db per square block (per division) for db values .. or if you measure a low loss filter or a cable also only 1 db per division (set that to your needs) ... that is for s11 return loss or for s21 trough loss
if trace shows swr then it can be 1 per division (default) ... or 0.5 (then swr 1:1.5 shows 3 steps up)
or it can be 0.1 per division (then a 1:1.3 would show 3 steps up and 1:1.5 shows 5 steps up)
etc etc (i will not list all here)

now a bit clear?!?

Google is your friend. (Actually DuckDuckGo in my case.) So is Wikipedia.

A bargain! The first network analyzer I used I talked management into paying about 50 grand for it. As I recall, it didn't come with much of a manual, either. But they did have workshops you could pay a few grand for to learn how to use it. Or you could spend hours reading and trying to understand their Application Notes, as I did. Those Application Notes are, for the most part, still available at the website of Keysight, formerly Agilent, formerly Hewlett Packard.

barnc4br 2020/12/27 06:47

JIM - THANK YOU - great explanation - I should read Wikipedia more since I support it.

barnc4br 2020/12/27 07:12

Siegfried Jackstien THANK YOU SIR. almost crystal clear ==> A couple follow ups
1. What does RESET and RESET ALL do? What does each reset?
reset resets calibration ... reset all also scan area (100 to 900 megs)
................................................... what does that mean?
My impression was reset all reset items to default. I just don't know what all those default items are. I have found some of them that changed. And RESET only clears the calibration data otherwise you would be calibrating the calibration.

6. Jim came up with it == https://en.wikipedia.org/wiki/Window_function
7. appears correct. done apparently turns it on. Not sure why one would want to turn it off.
8. it is just for viewability as the data does not change, right?
11. or 0.5 (then swr 1:1.5 shows 3 steps up) or it can be 0.1 per division (then a 1:1.3 would show 3 steps up and 1:1.5 shows 5 steps up) === shouldn't the first one be 1 step? Looks like the others measure level over 1?

Thanks again.
