All N2PK VNA software developers are encouraged to support the fast detector and the dual detectors in the Expanded N2PK VNA. The architecture of the dual detector N2PK VNA allows simultaneous real time display of reflection and transmission, as shown here: |
When the fast dual detectors are functioning at their faster rates, the combination of simultaneous display of reflection and transmission can be very useful during adjustment of a variety of DUTs. |
Also, even without the S-Parameter Test Set which is needed for 12-term error correction, a dual detector VNA can provide improved transmission measurement accuracy over a single detector VNA by being able to account for additional error sources. |
Item 13 above shows a block diagram of a VHF/UHF VNA Transverter (Fig. D) that extends the capabilities of the Expanded N2PK to 500 MHz in narrow band fashion. Simpler transverters, compatible with a single (slow or fast) detector N2PK VNA, are shown in item 17 above. All N2PK VNA software developers are also encouraged to support "VNA Transverter mode" or "Synchronous Common LO up/down mixing mode" as it is currently referred to in my software below. |
If you print the PDFs, use the "Fit to page" option in Adobe Acrobat Reader. |
To download Adobe Acrobat Reader which is needed to view PDF files, click here. |
An unZIP program, such as WinZIP, will also be needed. |
First click on one of the README files for software installation instructions and usage of my DOS based software. Then download the software. The PDF has been bookmarked and could be a handy reference. |
The above software does not currently support the fast or dual detector VNAs. If you would like a copy of some incomplete beta software, please send me an e-mail requesting it. |
Some other sources of software, compatible with the N2PK VNA at
various levels, are Windows based and as follows in alphabetical
order:
