doing simulation in ADS for pulsed RF loadpull

hi i wanted to do the simulation for GaN device under pulsed rf and pulsed dc condition. would you please help me how sahould i do that? is it possible to guid me how should i do loadpull at this conidtion?! my main problem is how to impelemt and program the pulse condition in the ADS.

Dear Yashar, If your device's simulation model implements some kind of time dependency (like self-heating), you will need the Circuit Envelope simulator and use a time-domain (voltage) source for your bias circuitry and a pulsed-RF source for your RF signal. On both sources you specify the pulse start and duration. All your simulation results…

RF MMIC : BGA6130 PA S parameter simulation in ADS

Dear Sir, I am Sagar Mistry from System Level Solution PVT Ltd(India). I required technical support and guidance regarding the simulation of two-port S- Parameter of NXP BGA6130 PA in Keysight ADS software. I need to evaluate the Gain response of the BGA6130 PA over the frequency response by changing the value of the matching network. … (Show more)

Dear Sagar Mistry, Your first step is to request the simulation model file(s) for the BGA6130 from NXP. Preferably a Touchstone S-parameter file, since you are planning an S-parameter simulation. (Keysight does not (can not) provide (up to date) device models for all the parts of the world's RF component manufacturers.) The S-parameter file can…

IO Libraries Suite Windows 10 Installation Issues

Hi, is anybody else experiencing issues with installing IO Libraries Suite on Windows 10? I tried several versions including 2019 Update 1 (IOLibSuite_18_1_24715.exe) and got a range of error messages as can be seen in the attached PDF. I have tried installing with the Windows Virus and Threat protection disabled but it made no difference.… (Show more)

Hi JacoEngelbrecht, I'm the support engineer for IO Libraries Suite. I'm sorry for the late response but I've been having trouble accessing the forums and only today it was fixed by my IT. I appreciate you posting your resolution steps here. I have forwarded it to our developers so that it can be an FYI or it can shed some light on the root…

Multi-Interface MRTG Graphs?

I've got a CentOS box collecting SNMP data from some networking equipment, and publishing MRTG graphs on a network status page for our company. We have two physical connections to our primary ISP connecting into two separate physical routers in our core. I have MRTG polling both routers and getting traffic graphs dumped into two separate RRD… (Show more)

Tools for Data Storage and Manipulation

Hey everyone, I come from a software development background and have been trying to move into a data science role recently and I have a few practical questions that I'd love some opinions/discussion on. Are relational databases still a good solution for large feature sets? I'm used to using Postgres or similar for storing data, but I'm working… (Show more)

Synchronizing two UXG N5193A

Hello, I am trying to synchronize two UXG N5193A to generate phase aligned LFM pulses and having an issue. I connected 6GHz reference, trigger signals and RF sync as shown in "Multi-Box Synchronization Application Note" and went through the synchronization process, it was done without any error. On the pulse setting of the master box, I… (Show more)

8590B no calibration after memory loss

Hi, I have at work one 8590B that has suffer of boring problem of backup battery dead. I have replaced the battery (both lithium and supercap) and I tryed to recalibrate the instrument. When I performed early attempts, the 8590 says that not found the calibration signal. In effect it was displayed with a considerable offset. I have tryed a… (Show more)

Does the 4000X D4000BDLA option include the waveform generator

The software bundle for the 4000X scopes, DSOX4APPBNDL, has been replaced with D4000BDLA. At first, it appears that the new bundle has a price reduction ($3450 for new vs $4800 for old). But, the old software bundle included the 20MHz waveform generator in the scope (DSOX4WAVEGEN2) and from the datasheet for the new D4000BDLA bundle, it looks… (Show more)

CPW port in EMPRO

I want to simulate a Ground-Signal-Ground waveguide (ungrounded) with EM PRO. What is the best way to model the port? I've seen examples where a multimode port is used (with 3 modes, one for each conductors) but the example was for a grounded CPW. Thank you. e.

I am using N5242B ( SMC and NFx applications) to measure an up/down converter. The conversion gain and NF are showing higher value ( 5dB) than a standard setup ( Sig Gen and SA). Is there any thing critical I am missing in my PNA settings? Thanks

My DUT input is at -30dbm and expected conversion gain is 20dB. The PNAx is measuring 25dB.

The only likely reason that comes to mind is calibration (assuming you calibrated your SMC and NF measurement setup). if you made calibrated measurements with the PNA, but not in the Source+SA method, the cable losses in the uncalibrated measurement could account for the lower gain reading in the gain measurement. besides that, we'd have to see…
