N2140A Keysight

Safety and Regulatory Information The probe cable is a sensitive part of the probe Keysight N2140A and N2142A and, therefore, you should be careful not to damage it through excessive bending or pulling. CSA is the Canadian certification mark to Avoid any mechanical shocks to the product to demonstrate compliance with the Safety requirements. Passive Probes guarantee accurate performance and protection. Do not use the probe assembly if the red wear The CE mark is a registered trademark of the Quick Start Guide indicator in the cable has become visible. European Community. ISM GRP 1-A denotes the instrument is an Industrial Scientific and Medical Group 1 Class A product. ICES/NMB-001 Some of the probe tips / accessories are very indicates product compliance with the Canadian sharp. You should handle these with care to Interference-Causing Equipment Standard. avoid personal injury. This symbol indicates the Environmental Protection Use Period (EPUP) for the products toxic Use only Grounded instruments. Do not connect 2 the probes ground lead to a potential other than substances for the China RoHS requirements. 3 earth ground. Always make sure that the probe IEC Measurement category II is for measurements and oscilloscope are grounded properly. CAT II 1 performed on circuits directly connected to the low voltage installation. Example. Household 4 Connect the probe to the oscilloscope and appliances portable tools, and similar equipment. connect the ground lead to earth ground before connecting the probe to the circuit under test. 5 6 Disconnect the probe input and the probe ground lead from the circuit under test before 7 disconnecting the probe from the oscilloscope. Indoor Use Only. Do not operate in wet / damp environments. Keep product surfaces dry and clean. Do not operate in an explosive environment. Keysight Technologies 2017 If your probe requires cleaning, disconnect N2140-92001, June 2017, it from the instrument and clean it with Printed in USA mild detergent and water. Make sure the probe is completely dry before connecting it to the instrument. *N2140-92001*The Keysight N2140A 200 MHz and N2142A 75 MHz passive These probes have been designed and calibrated for use Table 2 - Electrical Characteristics probes are high impedance probes with switchable attenuation with instruments having an input impedance of 1M ratio (1:1 and 10:1). These are compatible with the Keysight paralleled by 20pF. However, these may be recalibrated for Value Characteristic InfiniiVision EDUX1002A/G and DSOX1102A/G digital storage use with instruments having an input capacitance of Attenuation Ratio 1:1 / 10:1 oscilloscopes or similar oscilloscopes with 1 Mohm BNC input. 15 to 30pF. Input Capacitance 1:1 - 100pf 10:1 - 15pf Adjusting Probes for Low-Frequency (LF) Compensation Compensation range The BNC connector of these probes has a 15pf - 30pf The probe should be adjusted for LF compensation when it is (when terminated pin hole without a pin. This is as per the into 1 Mohm) connected to an oscilloscope input for the first time. LF design and does not indicate any damage compensation matches the probe cable capacitance to the or fault in the probe. Input Resistance 1:1 - 1M 10:1 - 10M oscilloscope input capacitance. This matching assures good Pin hole amplitude accuracy from DC to the upper bandwidth limit Maximum Input 1:1 - 150V rms CAT II without frequencies. A poorly compensated probe clearly influences Voltage 10:1 - 300V rms CAT II BNC a pin the overall system performance (probe and oscilloscope) Connector Current Rating and introduces measurement errors resulting in inaccurate 0.15mA (DC, 1:1, & maximum voltage) readings and distorted waveforms. For optimal probe compensation: For N2142A For N2140A Bandwidth Table 1 - Probe and its Supplied Accessories - Allow the oscilloscope (with the probe connected) to warm 1:1 - 6 MHz 1:1 - 6 MHz up for at least 30 minutes. 10:1 - 75 MHz 10:1 - 200 MHz Quantity - Repeat the compensation steps if the ambient temperature ID Part in the area in which the oscilloscope is being used changes For N2140A For N2142A Table 3 - Physical & Environmental Characteristics by more than 5 degrees C.
