A Bode Plot Without Access to the Control Loop
November 23, 2021 Steve Sandler This extreme measurement seems more impossible than difficult. The traditional stability assessment...
Siglent App Note: Measuring Power Supply Control Loop Response with Bode Plot II
In this application note, we will show you the basic principles for making this stability measurement and how to use these instruments to...
Convert Voltage to dBm and dBm to Voltage (peak-peak and RMS)
dBm is power referenced to 1mW, where Rref is the system impedance Since most systems, including the Bode 100 are 50Ohms, this can be...
Three Stability Assessment Methods Every Engineer Should Know About
Many engineers are familiar with the Bode plot as an effective stability assessment method. However, some authors suggest and even teach...
FAQ #18: What injection resistor value should I use? Is it okay to use a little larger resistor like
What injection resistor value should I use? Is it okay to use a little larger resistor like 30 or 50 ohm instead of 5 ohm (like many app...
Why Network Analyzer Signal Levels Affect Measurement Results
When measuring a circuit or device with our network analyzers, engineers generally inject a signal and believe that the measured results...
Signal Injection Transformers – What makes them special?
In this article we’ll take a look at what makes the signal injection transformer special, why an audio or video transformer is not a...
FAQ #14: Please specify what is the maximum AC injection signal voltage and current for the J2120 Li
Please specify what is the maximum AC injection signal voltage and current for the J2120 Line Injector? We need to measure PSRR of our...
FAQ #9: My Bode plot doesn’t look right, what am I doing wrong?
My Bode plot doesn’t look right, what am I doing wrong? The most common error made when measuring Bode plots is that the signal is too...
