The Picotest P2106A probe is a high impedance voltage divider ‘Browser’ probe, specifically designed to be low bandwidth and resonance free. When paired with the Picotest J2180A low noise amplifier and PDN cable, the low noise measurement can be connected directly to any 50 Ohm instrument, including signal source analyzers, spectrum analyzers, and low-noise oscilloscopes. The P2106A provides one of the lowest noise floor testing solutions allowing measurement of sensitive power supplies for power amplifiers and telecommunications equipment up to 65V. The bottom resistor is typically 1K and the tip resistor sets the attenuation. The P2106A-20K-20X has approximately a 19K tip resistor and 1K bottom resistor. This ~1kOhm Thevenin impedance forms a low pass filter with the coaxial cable (30pF/ft) and the J2180A low noise preamplifier input capacitance (~36pF) (Fbw=1/(2*PI*1k*125pF)=1.2MHz. There is essentially zero capacitance at the probe tip. The general application is to connect a relatively High Z, uncompensated probe to the J2180A amplifier for the purpose of getting a low noise, low bandwidth signal to a 50 Ohm instrument. The P2106A is available in fixed pin pitches of 50, 60, or 100mils). The P2106A probe can be purchased in almost any desired attenuation. Using an uncompensated voltage divider results in near zero capacitance and is assured to be resonance free for accurate measurement with minimal loading. The uncompensated divider results in a low bandwidth measurement, set primarily by the coaxial cable and J2180A preamplifier capacitance.
