    Defekt SPWM-Modul 1500W inverter

    Hi, basically a better picture of the already provided one is needed, which shows the part numbers on the (large black) ICs (chips), as well as how they are connected to the surrounding parts. BR

    ADS Rectifier Design problem

    Hi, it's quite a while ago since I used ADS, but is it even possible to run both analyis at the same time? Have you tried to run the simulation when only TRANSIENT or S-PARAMETERS is enabled. Further, is P_1Tone actually connected, its connection might be coverd by the width (1.5 mm) of the...

    Understanding analog multiplexer internal circuitry that contains extra MOSFETs

    Hi, that should be the "break before make" implementation. Each inverter will add a delay, ensuring a faster turn-off of the switch by the NAND, while the NOR will turn on the switch later. Consider two of this switches getting controlled at the same time, one should be opened, the other one...

    ADC readings does not correspond with input power

    This discussion might help. BR

    Looking for SPICE Model of PNP

    Decrease the increments in your DC analysis from 10 (at the moment: .dc Vin 0 -3.3 10) to e.g. 0.01. That's your voltage step/increment. At the moment you only cover "1" step, as your voltage span of interest is only from 0V to -3.3V. BR

    ADC readings does not correspond with input power

    @std_match of course you are right. I was suspecting the doubled power by the wrong use of the attenuator, and it looks to me it is set to 0 dB. But in the picture a a 50 Ohm terminator can be seen on a BNC-T connector as well.

    ADC readings does not correspond with input power

    Have you set the attenuator to 0 dB? If so have a look here, to see how the attenuator works for a 0 dB switch position.

    ADC readings does not correspond with input power

    An attenuator is a series element with a certain attenuation e.g. 10 dB. A termination will be connected towards GND. Please clarify what are you using, or better show us what are you using. BR

    ADC readings does not correspond with input power

    Hi, what is your signal frequency? Here you see a 3 dB change of your power (dBm), which means that there is twice the power present. What is the input impedance of your circuitry? If it is HIGH-Z, the signal gernerator will simply provide twice the power, as it is supposed to deliver it into...

    Looking for SPICE Model of PNP

    Hi, you have only changed the reference designator from "Q1" to FMMT591. You have to change the "value" PNP to FMMT591, see my attached image in the previous reply. BR

    help finding in catalog wider version of PTTC-704

    Hi, simply check the website from METCAL, ther I found 31 tips which are wider than 6.35 mm (0.25" - PTTC-704). Which one is suitable for your solder-tweezer handle I do not know, as you have not mentioned, altough I assume the MX series. There are still 10 tips (wider than 6.35 mm) listed for...

    Looking for SPICE Model of PNP

    Hi, your model is a ".MODEL" whic is intended do be used with an intrinsic Spice device, see here and also this video. BR

    Smd markings

    Hi, I assume the devide marking is "660A". It is manufactured by Fairchild. It might be the NZT660A PNP transistor, check if it make sense by its connection in the circuitry. BR

    Mapping Camera Image to (PCB) Production Data

    Hi, I'm interested in the temperature of specifice components on a PCB. Therefore, an image with a FLIR camera has been made. To allow an easy extraction of the component information, I would like to map the thermal image to the production data of the PCB i.e. pick and place and drill/mill...
