I recently started working with a P5008a VNA. I want to command it with LabVIEW. So as I found in the website, I had to install Command Expert. This would allow me to have the LabVIEW Add-on for Command Expert.   Here comes the problem, I can't seem to find the Add-on on my LabVIEW.   I already had LabVIEW on my computer before installing… (Show more)

This is regarding X- band Power amplifier simulation  with cree 100 W device (CGHV96100F2) for radar application. The S-parameters  results are as expected in circuit simulation and layout simulation. The moment we do EM simulation, results are not at all matching . Kindly look in to the workspace shared here. also

I am evaluating phase noise on an eval board from SiLabs for a 100MHz oscillator. The eval board has SMA connectors on the oscillator outputs and when I connect through them to my U1818B probe to my E5052B SSA, I can almost perfectly replicate the phase noise profile offered in the SiLabs datasheet (see Orig_config_w-gnd.png attachment). However,… (Show more)

Click to view contentHi, i'm measuring the attenuation of a variable attenuator (ZX73-2500-S+). With supply voltage, control voltage and input power fixed and the frequency varied around 3GHz, i've measured the plot below.     Is that expected when not changing the frequency setting of the E4419B? If so, what does this setting do? My setup:  … (Show more)

Hello Everyone,     This is regarding  results difference in circuit simulation and EM simulation of 2 way divider at 1.3 GHz . when EM simulation id done for 2 way PDC , there is huge difference  in S-parameters compare to circuit simulation. Why is this happening ? Can any one help in this regard?@

I'm using ADS2020, running a PCB model in Momentum that includes an instance from EMPro. After layout simplification finishes, the simulation fails and returns the message "Done (job failed) (results installation aborted)". How do I troubleshoot this?

I recently acquired a HP8752A. This is a wonderful VNA. But I have a Question: Each time when I have stored a calibration in internal memory I loose the entire calibration data when the VNA is switched OFF. When switched ON again all cal data are lost. When I keep the VNA running , I always can access the calibration at all times, even with a… (Show more)
