    ADS Touchstone combiner

    HI ALL, I have 6 s2p file. if i combine them in a S4P file i will get the same behavior if combined in a one S2P file ? Regards

    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U20.L4. You may break the loop by adding a series resistance

    I have a transmission line in the circuit which represents the my twisted harness (+data,-data) so it's a balanced 2 port simulation circuit, then i have my dut(4port unbalanced ciruit) and while working with a 2 port VNA i have to generate aS2P files to be combined in order to get the standards...

    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U20.L4. You may break the loop by adding a series resistance

    Here is my approach : i am working on creating a simulation model of the BCI test. to model the PCB in the simulation circuit i have to measure the s-parameters of my DUT (balanced 2 port/unbalanced 4 port) with the VNA (BODE 100) to generate the touchstone files (S2P), after that i combined the...

    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U20.L4. You may break the loop by adding a series resistance

    i measured the s-parameters then i generated the spice cirtcuit using ADS. I used the PI spice model with naraw band spice model generator . and i am working on a range of frequency of 0-50 MHz. can you please help that wich generator can i use and how to configure it to get the right spice...

    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U20.L4. You may break the loop by adding a series resistance

    Hi all, i want to know the input and output of that spice library or how the elements of the circuit are placed, any help ?

    Bode 100 s-parameters measurement

    Hi all, I am working on the s-parameters measurement with 2 port VNA ( Bode 100 ) and i want to generate the S2P files to be combined after to get S4P file. my question is that for 4 ports networks how much the number of S2P files i HAVE TO generate ? 1622187433 Also i am working on the BCI...

    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U20.L4. You may break the loop by adding a series resistance

    Thank you for reply, Can you please tell me how can i ground internally the filter from the library because i don't know how the elements of the circuit are placed knowing that the lib is generated by spice model generator from s parameters measurements ? Regards

    ADS spice model generator

    i have generated the spice model but that i can open with model editor but wirh .cir extension i want to know if i can genarate the .lib one ?

    ADS spice model generator

    There is an extension (.cir). The spice model should be generated with .lib extension ? I selected all files, then i had what in the second picture attached, do you have an idea waht next ?

    ADS spice model generator

    About the settingS : input file type : touchstone file : S4P spice model output : i specified only the name and i don't know how or where the spice model will be saved, any idea ? 1622045288

    ADS spice model generator

    Thank you, My goal is that i have to represent the PCB with s-parameters measured by VNA in a simulation model (ORcad), and what i undernstand from your saying is that i dont have to convert from standards s-parameters to mixed ones. One other question plz, for the spice model generator, what...

    ADS spice model generator

    Hi all, i want to save only the Sd2c1 from the spara checker, any idea ? then from Sd2c1 i have to generate a spice model to be used in orcad, should i use Narawband or BroadBand Spice Modele Generator ?
