Recently published in VRF - quote directly from Keysight. "VEE will not be officially supported on the Windows 10 platform. Users who need to migrate to Windows 10 can still run VEE programs on it, albeit with some restrictions due to the loss of some capabilities after the migration. In light of the issues around post-migration, we will avail… Show more
Hi All Now that the "cat's out of the bag" I would like to thank all the HP, Agilent, and Keysight folks who created, maintained, and lobbied for Visual Engineering Environment (VEE) for the last 26 years. It is an example of the best of next-bench and has been a great productivity tool for the many of us who are not software professionals.…
I wonder if N7555A Ecal can be use as Noise Figure tuner for PNA-X. Any issue to used that Ecal as a tune? Regards, Mirek
There appears to be a bug in the firmware preventing these new ECals from being used as a tuner for a vector NF calibration. they can be used for performing the S-Parameter cals and we have one of our engineers looking into why it is not showing up as a tuner. I will update you here when we have more information. Keep in mind that we have not…
Hello Does anyone have the sample Python script controls E4990A and gets trace data from it ? I am going to try USB and PyVISA to connect to E4990A. It would be helpful if someone shares the script with me. Thanks in advance. Toru
I have tried to perform simple 1-port waveguide calibration with E5071C analyzer. When I have measured short , offset short and fixed load "done" button stays still grey and it can't select. Why so, even I have measured all needed components? I have never had such an issue with coaxial calibrations. Should I do something before waveguide… Show more
Im making a measurement where it would be handy to remove measured losses associated w a transmission line. I notice that some of the newer network analyzers can do this w port extensions (loss removal) and fixture simulator (adjusting impedance). What is the best way to approach this with a 8753ES? Matt
Hi There, I have one PNA-X that occasionally found "low disk space" about 30 days range occurance. May I know is this refer to it's CPU or the PNA-X applications that having low disk space and what is causing this? Any inputs and comments are appreciated. Thank you. Best Regards, Tze Chen
when making measurements on an antenna using a foeldfox will interference from nearby transmissions cause an error in the displayed impedance values?
The measurements were on an MF antenna system on which there were signals from local high power AM stations with an amplitude similar to the signal level from the Fieldfox at the input to the antenna matching unit.The matching unit has automatic tuning and resistance adjustment with the objective of providing 50 +j0 ohms at the input. The fieldfox… Show more
We are performing a time-domain measurement of S21 at a particular frequency by changing the sweep time option of the VNA. So, for the purpose of the following questions, assume that a VNA is configured as follows for a measurement: 1) No averaging; 2) Fixed IF bandwidth; 3) One sample point (one frequency point is sampled); 4) One network… Show more
How do I safely measure S-parameters at 10 Watts up to 5GHz on an ENA? I need to measure the RL and IL of a passive device on an ENA at 10W continuous power, swept up to 5GHz. I need to do this without "frying" the ENA How would I go about doing this safely? I'm not sure what kind of equipment I need.
Hello everyone.I read about this on Keysight's website,but I can't figure out the window expansion factor.If I use different window to take spectrum analysis,the ADC record size will change(window expansion factor is different for different window).I want to know how to calculate the window expansion factor.Thank you!

HI i am new at RF characterization techniques . I am currently working on the uncertainty estimation for a measurement based on one port S11 reflection measurement. I download the uncertainty calculator and introduced my analyzer and calibration kit. What i want to know is how i have to apply the uncertainty charts for the S11 magnitude and phase… Show more
