I am attempting to automate the AFR de-embedding process, through the PLTS COM interface. For reference, I am using .NET in Visual Studio. I can successfully execute certain commands (such as plts.ImportData(), plts.ImportFile(), etc.), but when using the plts.Afr() command, nothing happens. Furthermore, using the plts.GetLastError() command…(Show moreShow less)
The standard 8753D/E/ES have the built in test set. Option 011 removed the test set, which is less convenient, but more flexible. I can’t quite recall what the very rare option 014 gives one, but it is at least some access to the internal test set. I suspect it gives direct access to the receivers. That seems the ideal 8753 to me, but they are…(Show moreShow less)
I am working on a deal to upgrade my 8753C with 84074A 6 GHz test set to an 8753E. I need to decide whether to keep the existing test set and get an option 011 analyzer, or get a unit with the integrated test set. From looking at a comparison table I found, it appears that the integrated test set offers 10 dB greater dynamic range below 3 GHz…(Show moreShow less)
It's been a while (I designed in the 85047A in 1986), but I think the difference is the external test set uses a bridge/coupler for the reference channel tap, where the integrated uses a 2 resistor splitter, so it has a bit lower source power and a bit lower dynamic range. The low end performance should be similar but I think the DC blocking…
After doing a 2-port cal, only the port 1 extension seems to work. I am using the same length extension coax for both ports. For port 1, I attach the extension coax with an open end and bring the Smith Chart back to infinite ohms and zero J to get the delay time in ps. Clicking on port 2 after I have added the coax extension to it, doesn't seem to…(Show moreShow less)
Hi, We use a 4 port E5071C for basic matching and tuning of our various NMR probes here at our lab. About 12 months back Keysight repaired our instrument, one of the channels was bad. Here we are again and we are seeing another fault, this time on Port #2. We normally use only sweep between 65 MHz and 1.2 Ghz but attached is a screen shot…(Show moreShow less)
Many thanks for your help Dave. I will attempt to answer your questions. Having asked some of the personnel in the dept it would seem some people turn off the correction, some leave it on. I cannot answer further. We do have a calibration kit, occasionally used. But just tuning NMR probes, its not considered important. No one is about to…
I am using LabVIEW 2016 on a laptop, connected via a GPIB to USB converter, to control a fieldfox N9917A in the SA mode. I'm trying to save the data as a csv and a screenshot/image of the sweep from the fieldfox to a predefined folder on the control laptop. I can only find options for saving to Internal/USB/SDCard. What is the operation or command…(Show moreShow less)
Hello, The FieldFox units are a Windows CE or Windows Compact Environment. Unlike a Wndows OS based system you are unable to map a share drive via LAN as some virtual resource from the FieldFox to the controlling PC. Thus you cannot save directly to the controller. You can save the *.csv and *.png image files on the FieldFox mass storage areas…
Greetings, I am experiencing an issue where once I login to our windows 10 machine, the screen is completely black but I can move the mouse cursor. I can boot up into safe mode. I've also tried the solutions listed here: https://support.microsoft.com/en-us/help/14106/windows-10-troubleshoot-black-screen-or-blank-screen-... I'm running windows…(Show moreShow less)
Some of us have seen this before; usually on our own laptops. A reboot usually fixes this. Is this still an issue? Does/did a reboot fix this? This seems to be a Microsoft issue, but we can try to help. If a reboot does not help, you may have to try a recovery of the SSD.
This might fix it - and is worth a try: Try running the PNA application as admin just once. Exit the firmware. (exit 835x.exe) Right click on the "Network Analyzer" shortcut Select "Run As Administrator"
Hello Keysight experts. Due to My N5290A system works not well recently, I did system recovery then upgraded the firmware back to version A12.85.08 which it was. However, when I tried to change operation mode from “Standard PNA” to “N5290A broadband system”, the error message ”invalid configuration” always shows in the same application window.…(Show moreShow less)
Hello, It turns out that in the past when I saw this issue come up it was due to having a corrupted configuration file for the mm-wave setup. So the best way to resolve this type of issue is to find the following file: C:\ProgramData\Keysight\Network Analyzer\mmheadconfiglist5 Then remove the file and the restart the VNA application and…
