Scope Probes Measure Transient Currents or High-Voltage Signals

July 08, 2013 by Jeff Shepard

Rigol Technologies, Inc. has introduced the RP1000 Series of oscilloscope probes, the latest addition to their line of passive and active differential probes. The RP1000 series measures current or high voltage signals and includes eight new probes designed to fit any Rigol oscilloscope. DP 800 Series ProbePerfect for high-speed transient current measurements that can't be easily detected with passive current probes or other methods, Rigol's RP1003C, RP1004C, and RP1005C current probes measure higher speed currents up to 100 MHz when used with the RP1000P external power supply. Similarly, RP1001C and RP1002C current probes enable direct measurements of currents up to 1 MHz or 100A dc and are designed for R&D applications, especially in power supply design and testing.

Rigol's RP1025D, RP1050D, and RP1100D probes are passive, high voltage differential probes intended for 25-, 50-, and 100-MHz applications, respectively, and are designed for voltage measurements up to thousands of Vpp. Other probes from Rigol include the RP6150 1.5 GHz passive probe for scope voltage measurements from slow waveforms up to gigahertz frequencies. Additionally, the RP7150 differential active probe is ideal for more accurate or differential high-speed signal fidelity from high-speed oscilloscopes such as the DS4000 and DS6000.

With these latest additions, Rigol oscilloscopes and accessories fully satisfy the requirements of a wide variety of power applications where accurate measurements combine with deep memory and on-board analysis to improve design, service, or production testing of current or high voltage signals. Current probes can also be used with any Rigol UltraVision oscilloscope to scale current measurements. UltraVision-based scopes allow engineers to set the units and gain factor for each channel so current measurements are correctly scaled and displayed.

The on-board analysis functions of UltraVision oscilloscopes enable an engineer to see the periodic nature of the current fluctuations, as signified by the color changes in the analysis bar along the bottom of the display. Prices for the RP1000 series start at $700. Some models are in stock and available immediately, others may have up to several week lead-time.
