Developed to aid power supply designers in control-loop stability analysis, Picotest’s line of signal injectors are being introduced as...

Written by Steve Sandler Featured by Penton Media in EDN, Power Electronics, and Microwaves & RF This article demonstrates how the G5100A...

I was thinking about how a typical engineer would go about creating a SPICE model for a simple diode. This seems like a pretty basic...

Understanding the key parameters of diodes and other components used in reference voltage circuits can help avoid issues in different...

What Calibration Services do you offer? Apart from warranty repairs, calibration and servicing, done directly at Picotest, we work with...

What injectors should I order? Most users purchase cost saving “bundles” and we have several to choose from on our website.  Please see...

Please specify what is the maximum AC injection signal voltage and current for the J2120 Line Injector? We need to measure PSRR of our...

Which measurements (Output impedance Vout/Iout, audio susceptibility Vout/Vin, input admittance Iint/Vin and reverse transfer Iin/Iout,...

Is it possible to also measure the audio susceptibility (Vout/Vin) of a power supply with the current injector J2111A? Yes.  The J2111A...

Are all of these devices compatible with our Hewlett Packard 4194A Impedance / Gain-Phase Analyzer? Yes.  The Agilent (HP) analyzer will...

What are the main differences between J2100A injection transformer, J2110A solid state injector and the J2111A current injector? The...

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...

Why do I have to calibrate my measurements?  Isn’t the equipment calibrated? Yes the devices are calibrated, however for accurate results...

How do I choose between the J2100A, J2101A and J2110A? If you plan to measure PFC’s, then the J2100A is a good choice, whereas the J2110A...

Why do I need the J2111A if I already have an electronic load? The J2111A is not the same as an electronic load.  In many cases, the use...

How do I get a Bode plot with the J2111A? It is not possible to get a Bode plot using this method, only the phase margin; however it is...

Does the J2120A Line Injector work with negative supplies? No.  The J2120A is only for positive supplies and we do not currently offer a...

What is so special about an injection transformer and why should I buy one, it is pretty expensive? A good injection transformer has high...

I see that with the J2111A can perform the “non-invasive stability” measurement. I don’t understand what we can take away about stability...

I would like to measure output impedance using the J2111A Current Injector, but the 25mA offset is way above my typical operating...
