Another question, how to clear the data already exported to the "Alpha Numeric", I want to have this action taken place with my trigger.
Now I am working on a program with vee. The main function is to conduct several tests,for every test parts will be compared with the specified spec value. I now use the "comparator" and it will return the result of this test part.Because it should be say the sample is passed only after all the test parts return the pass result,but I don‘t know how… Show more
Howdy. Looks like maybe noone else is ready to give an answer, so... If you have a bunch of tests that have pass/no pass outputs from comparators, which it sounds like you have, then a very simple answer to decide if all the tests pass is to collect the results into an array (A) and then take the product (product(A). If the product is true then…
Hello. We are using agilent 34970a. We have installed keysight command expert and when we try to install the command set corresponding to 34970A the following error appears "Failed to install command set '3497x Data Acquisition / Data Logger Switch Unit'.Cryptographic error signing assembly 'c: \ ProgramData \ Keysight \ Command Expert \… Show more
I have the same issue with most of my test stations. Installing new SCPI drivers in Command Expert does not work anymore. The installation process stops at ~50% and ends with this error message. Maybe an issue with antivirus protection... but no way to bypass it so installing new drivers becomes impossible. I have the issue on several…
The newest polarization controllers, like the N7785C have a convenient SCPI command set for programming. The functions to generate a sequence of polarization states that can be repeatedly scanned and synchronized with other instruments is very powerful. This application note describes an application for measuring PDL or PER with a rapid all-states…
I have MSOX3032A scope with 1147B current probe connected to it. Can I degauss the current probe by some remote command to the scope?
I need to perform 4-port calibration with E-cal on E5080B remotely. The SCPI command I written is : SENS1:CORR:COLL:GUID:ECAL:ACQ SOLT,1,2,3,4 When E5080B(26.5GHz) + N4433A , this command works fine. However, the same one E5080B + N4433D , it can't calibrate and got error message as below : Error : -290 : Did not find one or more thru… Show more
Hello, I have a Keysight 8164B with PowerModule and LaserModule. I am trying to do a wavelength sweep. I am using Python. I manage to establish a connection to the device, I can also read ID and some values which are shown on the screen. But when I perform a measurement and then record results, it does not perform any measurements. Here is my… Show more
Hi Deralas, Maybe it is now just a matter of defining the right format for the binary data. I don't see that in your code, but probably there is a setting or parameter for the pyvisa queries. The power meter data should be 4 byte floating values and the wavelength data are 8 byte double floating values. Both are have little-endian ordering too.…
I am are using ENA E5080A and 85032F calibration kit. I performed 1-Port cal using 85032F(M) directly connected to port-2 of VNA and done port extension to remove the offset delay. I tried to extract the coefficients of inductance(using 3rd degree polynomial)of calibration kit definitions for SHORT standard. I measured inductance to find the L0,… Show more
The coefficients of the 85032F kit have been updated over the years, so is there any chance that the VNA has one set of definitions in its firmware, but you are reading the parameters from elsewhere? I believe at one point it was assumed that the male and female had the same coefficients, but improved ones have been published. Are you aware…
How to transfer file to E5052B instrument from PC connected via USB using SCPI commands? I have tried :FORMat:DATA ASCii :FORMat:BORDer NORMal :MMEMory:DATA "F:\a.txt" "SAMPLE" Instrument gives error "invalid seperator"
Hello. I am now using your 8164B laser instrument and the N7745A optical power meter. I was using BNC, 8164B Output trigger connected to N7745A Input trigger. What I want to know is that there are two SCPI instructions TRIG: CONF: DEF, and TRIGG: Conf. Which one should I use?
BRD Import Error: The Cadence Allegro "extracta" utility was not found. Cadence Allegro PCB Designer must be installed to import a *.brd file.
Tips: Importing a Cadence Allegro *.brd file into ADS requires an Allegro utility called "extracta". Please make sure that a Cadence Allegro PCB Designer installation is available, and that the location of its "extracta" executable is included in the ADS $PATH environment variable setting. Q: Cadence Allegro PCB has been installed, but how to… Show more
Hi, I had the same issue and got it resolved by adding extracta path to environment variable $Path. Click "Start -> This PC -> More -> Properties", open the "System" dialog. Open “Advanced system settings -> Environment Variables", find the environment variable "path", double click to open it. Add a new value of the extracta installation…

Hello, I am trying to find my way through ADS SI/PI to simulate a PCB trace resistor temperature field (DC and thermal analysis). Basically, just a jumper where 10V goes in, passing through a perfect 0R jumper and going to copper-trace resistor (~9.1 Ohms). Here a screenshot of how this looks like inside SI/PIPro: Since the pins of the… Show more
