Re: Power Meter

Nick Kennedy
 

To calibrate, you need a sine wave source of known power level and a step
attenuator. Actually, a single attenuator would work but it's better to
have multiple points. There's information in the User's Guide and the
software has a built-in function for power calibration.

The source should have a frequency somewhere in "midrange" - perhaps 5 to
15 MHz.

I homebrewed two simple sources for my calibration. First was the -10 dBm
square wave calibrator by Bob Kopshi K3NHI and a 10 dBm, 10 MHz sinewave
calibrator by VE7BPO that I calibrated to K3NHI's circuit. I used a
homebrew step attenuator. Attenuators are pretty cheap and easy to build

You can find some folders in the Files area that describe how people did
calibrations. The circuits and articles I described can be found on the
web. I can provide some of the articles and circuits if needed.

Other suggestions I've heard here also sound good.

Re: Power Meter

Sam Wetterlin has some information on his web site on how to build a calibrator and the theory behind the circuit. It is the fifth paragraph down, under the title "MSA Documentation Relating to Hardware" http://www.wetterlin.org/sam/

I made a version for myself and there is documentation on my web page along with Gerbers for OSH Park under "Calibration Source for VNA, PHSNA, Scopes or Spectrum Analyzers" http://www.k9ivb.net/VNA/index.htm

There was also a spreadsheet and documentation in the old Yahoo Groups File area [not sure where it is here] on how to calibrate with a battery and a pot by applying the DC directly to the AD8307 inputs.

Yes every measurement device require periodic calibration . But in my long long experience the standard test equipments manufactured my HP, R&S, Marconi, Anritsu etc maintain the calibrations for long long time . Actually if you are not a precision manufacture of systems these equipments are good for long time.

Re: Power Meter

Hi Alfredo,
It will be a over kill to purchase a power enter for calibration of AD8307 chip meter . If you have an access for an Oscilloscope and having a carbon resistor for 51 Ohms you can simply measure the voltage across the resistor and compare it with your Ad8307 chip values .
Power = Square of Vrms/50 . Nothing will be more precise than that and no need of sending power meters to be calibrated in US every now and then .

Well, today is my first time to look at the new group location also. But if

you are in the PHSNA group and are a member, the files area should be

visible.



First, the group location is here:




https://groups.io/g/PHSNA



From that home page in the upper left I see a list of 11 links and 'Files'

is the 9th one.



After you click files you may see that there are a lot of files and

directories. There's navigation at the lower right to go through four (4)

pages of files and file folders.



I hope this helps.



BTW, this message should have a line that takes you to the PHSNA home page.

Hello Ambro,
All of the software you need is in the folder "Windows PHSNA". That
includes two Arduino 'ino' files plus the Windows executable.
You will also find a user's guide for the software and a guide on how to do
the Arduino software installation, for any people not familiar with it.
There are sample "parameters.txt" and "memories.txt" files which the
Windows PHSNA program reads to configure itself for your specific system.
As for schematics -- since there are many variations on the software, I
recommend you first look over "PHSNA FAQ Sheet.pdf" which is in the top
level (last page) of the files area. I hope it will guide you to the
correct document for the schematics. But if there's any trouble, we can
help you.

membership in new PHSNA@groups.io

N5IB
 

A few members have submitted requests to become members of the new PHSNA group on groups.io

Please don't...  I'm not going to act on them.

All members here on Yahoo will automatically be added as members of the new group. It'll just take a few days to happen. As you might expect, the folks at groups.io have a pretty big backlog of transfers to accomplish. And they have to use Yahoo to do it - 'nuff said...  You'll get an e-mail when it's done.

N5IB




Tramsfer of group to groups.io

N5IB
 

I'm initiating the process of transferring this group to groups.io
It can be found at <https://groups.io/g/PHSNA>  All current members of this group will be automatically added as members of the new group. The message archives, files, links, and photos should also be transferred over.

Be alert over the next few days for an email announcing that the change over has been completed.
You should receive a message indicating that you have been added as a member to the new group.


During that time the the files, photos, and links will still be accessible to members here on Yahoo.

When the change is complete I will block new posts here on Yahoo, but will leave the Yahoo group otherwise intact for another week or two. So any folks who may not wish to participate in the new group will have a chance to retrieve any information they need.

N5IB sightings

To channel Mark Twain - rumous of my demise are greatly exaggerated  LOL

I've just decided to put most radio projects on the back burner for a  while.

Our first grandchild (Tessa Noelle) arrived last October. We've already been to SC once for a visit, and this week Tessa and her mom and dad are coming to visit and get her dad a crawfish fix. So the past month or so has been the preparations. No need to fully baby-proof - just yet -  but some space in the old homestead needed to be re-purposed. So plenty of chores  to occupy my time.

Someone commented about my website - yep, the n5ib.net site is gone away. I moved what stuff was there over to http://qsl.net/n5ib/  and sent a donation to Scott and his folks.

There was also a question about PC boards.
No current plans for another run, but there is a small handfull in the cupboard:
   Experimenter Boards v1.20  (10 on hand)
   Experimenter Board v1.04 (1 on hand)
   Type-2 PHSNA  v.03 (2 on hand)
   PHSNA for DDS-60/NANO  v 8.02 (6 on hand)
   Return Loss Bridge (3 on hand)

Besides those PHSNA-related boards I also have a few other bare boards:
Info on the website (above)
   Current Limiter boards (couple of dozen)
   Crystal spotter semi-kits (half dozen)
   Varactor Adapter for AADE LC Meter (dozen)
   RadI2Cino boards for the uBITX transceiver (info on the BITX io.group)

It'll be a week or so before I can attend to any requests for those.
the n5ib (at) juno (dot) com e-mail is still valid

There are probably some valid reasons to move this group over to groups.io, as many other ham-related groups have already done. I would entertain a volunteer to become a joint "list owner" and oversee the transition - especially someone who may already have done that task.

73 for now .... pre-Tessa tasks are still calling
