Hello, I have been looking into different measurement methods on how to verify the stability of the control loop of COT buck converters. Traditional methods like bode-plots don't really work because of the inherent non-linearity. Is NISM effective at obtaining the phase margin for COT devices?

I have a glance to the Bode 100 application note about battery impedance testing with your current injector: https://www.omicron-lab.com/fileadmin/assets/Bode_100/ApplicationNotes/Battery_impedance/App_Note_Battery_Impedance_V2_0.pdf and I was wondering whether you see any impairment in doing the sa

We’re trying to determine what pitch the end user wants for their P2104A 1-port probe ( https://www.picotest.com/Products_P2104A.html ).

So we recently purchased a P2102A and while I really appreciate the ability to use the provided fixed width probe tips to probe standard surface mount components like 0402, 0603, 0805, 1206, I'm in a situation where I am trying to do 2 port impedance measurements on a couple new components (a diode

We just bought VRTS 1.5 Demo Board and tried todo the bode plot for the output of the board , Figure1: shows the setup and everything is setup in accordance to the guidelines provide by siglent in the link below. Measuring Power Supply Control Loop Response with Bode Plot II - Siglent (siglenteu.c

I am taking an output impedance measurement using the 3-port (voltage / current) method. Here is my calibration test setup: I feel this is a very good test setup, and these are the shortest cables I can readily locate. Everything has the look and feel of "good working order" or is brand new. I us

Hi, I've been using this probe successfully with the 0402 head. I've been probing a DNI 0402 capacitor footprint, but after several measurement (with some down-force) the sharp pins are damaging my pads. I wondered if anyone had tried other probing structures? I was thinking of using 4 well-spaced P

I need to measure freq response of transimpedance amplifier which means I need to inject Current at input and measure Voltage at output. I have J2111a current injector and Bode100 in my lab so can you show me measurement setup by using these equipments.

We bought a couple of those B-Amp12 to boost the signal level for doing PDN measurements and I had a question about connections for the amp. The amp has connections for Ch1 and Ch2, If I connect those to the Omicron, how/where do I connect the other end of the P2102A probe? Does the Bode 100 SW rec

Whenever I used a VNA to measure s-paramerers, I would do a calibration, and that would remove them from having any impact on the end measurement results. Why is it that even after a VNA calibration for 2 port shunt measurement, you still have to use an isolator? Why isnt the calibration good enough

Customer: Hi Steve, I have my Friday’s questions for the weekend to relax with… · 1-port method - I do see that the Bode100 monitor both the voltage ahead of the reference source resistor and after the source resistor: o Why monitoring the voltage ahead of the internal resistor? o Is i
