National Instruments 784257-01 Single-Ended Active Oscilloscope Probe
The National Instruments 784257-01 (also known as the SA2500X) is a single ended active voltage oscilloscope probe designed for high speed measurement applications. It is suitable for capturing fast signal transitions and high frequency components with a bandwidth of 2.5 GHz. The probe offers an attenuation ratio of 10:1. This ensures accurate voltage scaling for measurements within its dynamic measuring range of ±8 V. It is ideal for use with oscilloscopes that provide 50 Ω input impedance that allows seamless integration into existing test setups for precise signal analysis.
The 784257-01 oscilloscope probe can handle a maximum input voltage of 20 V. The input resistance of the system is greater than 1 MΩ that minimizes signal loading and ensures measurement accuracy. The input capacitance of 0.9 pF further reduces signal distortion. This ensures that the integrity of high frequency signals is maintained during testing. The probe is powered by a 24 V DC auxiliary power supply which is included and it requires a current of 150 mA.
The environmental specifications of the 784257-01 probe make it robust for various working conditions. It operates in temperatures ranging from 0 °C to 45 °C and can be stored in extreme conditions from -40 °C to 71 °C. The operating humidity tolerance is up to 80% relative humidity at 31°C decreasing to 50 % at 45 °C. This allows the probe to function reliably in a range of environmental conditions. It can operate at altitudes up to 2,000 meters and be stored at altitudes up to 15,000 meters.
The 784257-01 probe is designed for Category O (CAT O) measurements limiting it to peak voltages of 20 V. This ensures that users can safely connect to circuits within this voltage range. The probe meets European directives including the 2014/30/EU Electromagnetic Compatibility (EMC) Directive and the 2011/65/EU Restriction of Hazardous Substances (RoHS) Directive.
The NI 784257-01 probe is lightweight weighing just 96 grams and features a 1.3-meter cable. This provides flexibility and ease of use in various test setups. The model is a reliable and versatile tool for engineers and technicians conducting high speed signal measurements in a wide range of environments.
