Beschreibung

The Picotest P2102A probe is 50 ohm transmission line 4-point probe (2 signal lines and 2 ground). This precision probe supports a variety of measurements including impedance (2-port series and shunt-through), transient step load, ripple, noise, TDT/TDR, PCB power rail, VRM (Voltage Regulator Module), clock jitter, and non-invasive stability (NISM). It has significant advantages over active probes and other types of passive probes. The P2102A is a referred to as a ‘browser’ probe for its ability to easily and quickly be moved from point-to-point/rail-to-rail simply by reseating the probe points. The probe achieves a very low inductance at the tip to mitigate space constraints on a dense PCB, while eliminating the need to add additional SMA connections or other test points necessary for impedance measurements. It is especially useful when there are multiple rails to assess and there is not time or PCB iterations available to provide test point implementations for each. Repeated measurements are simplified because connection is by simply touching the tip to existing output capacitor pads. The P2102A comes with 4 swappable probe tips allowing measurement across a variety of SMD packages such as 1206, 0805, 0603, or 0402. The P2102A probe tips are available as 1X, 2X, 5X, or 10X attenuations. This allows flexibility for users to measure across a wide range of voltages. As an example, the upside of the 2X probe is that it can measure 6.5VDC without DC blocks. The tradeoff is the attenuation increases the impedance floor. In short, this 2-port P2102A probe is best suited for VRM, power plane, and decoupling measurements. A power added benefit is that you can use Non-Invasive Stability Measurement (NISM) to assess power supply’s stability at the same time as you assess the PDN.
