Keysight U1561B Scope Probe 10:1 Operating Instructions This scope probe is designed for use with Keysight handheld digital oscilloscopes. Assistance For technical assistance, contact your nearest Keysight Sales Office or visit the Keysight website at www.keysight.com/find/assist for further information. Symbols Refer to instrument users guide for additional safety information. CAT III Category III 1000 V Overvoltage Protection. Refer to instrument users guide for 1000 V additional information. CAT IV Category IV 600 V Overvoltage Protection. Refer to instrument users guide for 600 V additional information. The UL Mark is a registered trademark of Underwriters Laboratories Inc. UL listing mark with the indicators andUS indicates the product compliance with both Canadian and U.S. requirements. Ratings The voltage rating and measurement category rating marked on the probe assembly are the maximum voltage and measurement category for the probe itself. The voltage rating and measurement category of the measuring instrument used with the probes might be lower. Refer to instrument users guide to ensure that no excessive voltage is applied or measurement in excessive measurement categories is made. Scope probe 10:1 CAT III 1000 V Hook clip for probe tip CAT III 1000 V, CAT IV 600 V Ground lead with mini alligator clip CAT III 1000 V Operation The test probe 10:1 can be used together with any test instrument that has an input impedance of 1 M and whose input capacity is within the compensation range (see technical details). When connecting the probe, always connect to the test instrument before picking off the test signal. When disconnecting the probe, first disconnect the probe tip from the test signal. The hook clip has to be pushed into the probe tip. The ground lead has to be plugged into the probe body. Technical Details Operating temperature : 0 C to 50 C Non-operating temperature : 20 C to 70 C Weight : 140 g Dividing ratio : 10:1 Input capacitance : 12 pF Compensation range : 10 pF ~ 25 pF Frequency range : 0 ~ 500 MHz Rise time : 1 ns Lead length : 1.20 m Input impedance : 10 M 1% a : CAT III 1000 V Rated voltage when using touch-protected test equipment a Frequency-dependent, see derating curve below. Making a reference connection The output signal always relates to a reference point. For optimum measuring accuracy, the shield of the test probe should be connected to this reference point by the shortest possible route. Compensation For an accurate indication of the measuring signal, it is necessary to adjust the capacity of the probe to the input capacity of the oscilloscope. For this purpose the probe has an adjustment screw in the handling section. Connect the probe to the oscilloscope and the tip to the reference calibration signal of the oscilloscope. Turn the adjustment screw until the oscilloscope shows an exact square wave. If the scope probe is used in a manner not specified by Keysight Technologies, the protection WARNING provided may be impaired. Instrument damage or personal injury may result. If any portion of this probe is worn or damaged, do not use. Maintenance If any portion of this probe is worn or damaged, do not use. This information is subject to change without notice.
