High-bandwidth active differential probes are essential in the field testing of signal integrity in high-speed electronic systems. A significant challenge is ensuring that the probe accurately ...

Measuring a specific point (node) in an RF circuit with a regular oscilloscope probe can disrupt the circuit's performance, even when the probe is set to a less intrusive mode. A solution is a ...

The probe has a large internal impedance, which, along with the oscilloscope impedance, divides the voltage signal by 10 (Fig. 1). This high impedance reduces loading on the oscilloscope and enables ...

High input impedance and low noise comes from a carefully-crafted JFET at the input pin, in a circuit that Caldwell cannot reveal. Again in a way that TI is keeping close to its chest, a pair of 100mA ...

Note that the near-field probe is essentially a low-impedance loop, so take care to connect it to a 50-Ω oscilloscope input—not a 1-M Ω input—to prevent reflections and ringing. In addition, when ...

Equivalent Circuit Modeling. The project proceeds with fitting the impedance spectrum with the inset circuit model in Figure 4 to get a meaningful explanation. The MFIA is able to export sweeper data ...
