DESCRIPTION:
 
P2105A 1-Port Low Noise TDR - Ripple Browser Probe Head
The Picotest P2105A probe is 50 ohm 1-port transmission line 'Browser' probe for TDR applications. This precision probe supports a variety of measurements using the 1-port reflection methodology including primarily impedance and TDT/TDR, but also ripple, noise, PCB power rail, VRM (Voltage Regulator Module), and clock jitter. It has significant advantages in comparison to active probes and other types of passive probes.
 
The P2105A 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 trace. The P2105A comes in various fixed pin pitches (20, 31, 40, 50, 60, 70, or 100 mil spacing with 1X attenuation; GSG SMA and custom pitches are also available).
 
The probe is compatible with all 50 ohm instruments, including the J2154A PerfectPulse TDR, vector network analyzers (VNAs), oscilloscopes, and spectrum analyzers. The probe is designed to work with the traditional single ended TDR setup.
 
P2105A Probe-Based Stepper (S10) Head
This probe head enables testing of very fast load current transitions, high peak and average power, via multiple form factors that previously were unavailable or impractical to accomplish. In particular, demanding low-voltage, high-current applications, including those found in data centers, AI, graphics, EV, and servers, can now be tested.
 
P2105A for Near-Field Testing Probe Head
One of the optional snap-on probe heads for the P2105A probe is a near-field probe head. Two H-field loop style heads are offered, 31 mils and 100 mils, each with different sensitivity to magnetic fields.
