PICO PicoConnect™ 911 AC-Coupled 4GHz 20:1 Passive Test Probe (TA274)
Manufacturer: Pico Technology
PicoConnect™ 911 AC-Coupled Microwave/Gigabit Passive Test Probe provides cost-effective testing of broadband signals or data streams up to 4GHz or 8Gb/s. Representing a price-performance breakthrough, this new high-performance test probe has less than 0.4pF tip capacitance and a ground-referred loading of approximately 960 ohms. It is much less invasive than the majority of existing and more costly probing solutions. To achieve measurement accuracies down to a few percent it is ratio-compensated for typical applications, such as the probing of transmission lines and ports between 40 ohms and 100 ohms (80 ohms to 200 ohms differential).
It provides a 20:1 division of signals, this AC-coupled probe blocks up to a max of 50VDC and has a +/- 0.5dB flat response from 120kHz to 2GHz.
Suitable for use with any measuring instrument with 50 ohm inputs, PicoConnect probes permit high frequency oscilloscopes and spectrum analyzers to examine circuitry, backplanes, interconnects, and systems without disturbing their function, accessing multiple channels affordably. Despite their attractive specification they are cost effective for analog signals as low as 500MHz or digital signals of 1Gb/s.
The PicoConnect 900 Series Microwave/Gigabit Passive Test Probes offer probe division ratios of ÷5, ÷10 and ÷20 in twelve probe models. Each model is supplied in two probe impedances to suit either low-voltage, highest-speed (e.g. typical digital applications) or higher-voltage analog and pulse applications. In each case, there is a DC- or AC-coupled option, the latter being important when DC bias must not be disturbed (as with HDMI, ECL, PECL and LVDS). The PicoConnect 900 Test probe Series is a set of interchangeable SMA(f) probe heads that can be used with any appropriate 50 ohm cable, or with accessories such as filters, dividers, amplifiers or further attenuation.
PicoConnect probes are characterized with a supplied 085 high-performance flexible coaxial cable, which achieves market-leading flatness and pulse response. The innovative in-PCB coplanar construction (patent pending) guarantees underlying microwave integrity as well as 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.
