A family of high-performance RF, microwave and pulse allowing cost-effective fingertip browsing of broadband signals up to 9 GHz. With less than 0.4 pF tip capacitance and ground-referred loading of 220 Ω to 910 Ω, the PicoConnect probes are less invasive than the majority of existing and more costly probing solutions. To achieve measurement accuracies down to a few percent they are ratio-compensated for their typical application: the probing of transmission lines and ports between 40 Ω and 100 Ω (80 Ω to 200 Ω differential).
Suited to interfacing with any measuring instrument with 50 Ω inputs, PicoConnect probes allow broadband oscilloscope and spectrum analyzer users to browse circuitry, backplanes, interconnect and systems, typically without interrupting their function, and to do so across multiple channels without breaking a budget.[Fingertip browse pulse shape as it propagates through a microwave path]Fingertip browse pulse shape as it propagates through a microwave path
The family offers probe division ratios of ÷5, ÷10 and ÷20 with impedances to suit higher-voltage analog and pulse applications. For each ratio there is a DC or AC coupled option, the latter important when DC bias must not be disturbed. The whole family is realized as a set of interchangeable SMA(f) probe heads that can be used with any appropriate 50 Ω cable, or accessories such as filters, dividers, amplifiers and further attenuation.

PicoConnect probes are specified and characterized with a supplied 085 high-performance flexible coaxial cable, with which they achieve market-leading flatness and pulse response. The innovative in-PCB coplanar construction (patent pending) guarantees underlying microwave integrity along with mechanical precision, strength and electromagnetic immunity. The passive design is inherently resistant to static discharge and demonstrates no significant overload recovery latency or error. The PicoConnect probes and multi-head probe kits are provided with solder-in accessories in a convenient carry and storage case.

All specifications are subject to change without notice.
Note 1: Line impedance range representative of most common 50 Ω (100 Ω differential) and 45 Ω (90 Ω differential) lines ± 20% mismatch.
Note 2: Line impedance range covers all typical transmission line or test node impedances in the range 0 Ω to 100 Ω (200 Ω differential).
Note 3: CAUTION: When using AC coupled probes, to avoid damage to the connected instrument ensure that it can withstand transient voltage equal to the DC bias of the test node divided by the nominal probe ratio.
Note 4: Typically it will be possible to scale results at the connected instrument to correct for this small nominal error.
Note 5: WARNING: For peak voltage above 46.7 V, to ensure that touch current lies within acceptable limits of EN61010: 2010, pulse or burst width must not exceed 500 ns and pulse mark:space must remain below 2%.
Note 6: CAUTION: To avoid damage to the probe, RMS voltage over the pulse period must remain within specified probe rating.
Note 7: Probes having unmatched output impedance will not absorb pulse aberrations that reflect off mismatch at the connected instrument input. Pulse fidelity and flatness are therefore more dependent on good instrument match.
