DP001xA Series Differential Active Probes

データシート

For Keysight InfiniiVision X-Series and Infiniium Oscilloscopes

 

Introduction

 

Keysight Technologies’ DP001xA Series differential active probes provide the superior general-purpose differential signal measurements that’s required for many of today’s high-speed power-related measurements such as motor drives, automotive differential bus measurements, and high-speed digital systems design. The DP001xA Series differential active probes are available in bandwidth models ranging from 250 MHz up to 1.7 GHz with a wide input dynamic range and a probe offset range up to ±60 volts.

The DP001xA Series probes are equipped with Keysight Technologies’ AutoProbe1 interface that provides power and DC offset to the active circuitry of the probe’s differential amplifier, as well as automatic attenuation settings based on the oscilloscope’s vertical scale setting. These probes are compatible with most of Keysight’s InfiniiVision X-Series and Infiniium oscilloscopes that provide selectable 50-Ω input terminations with the AutoProbe1 interface. Select from the following models to meet your differential probing requirements.

 

Probing Accessories

 

Keysight Technologies’ DP001xA Series differential active probes come in a hard plastic carrying case and are supplied with the standard accessories shown in Figure 2.

For replacement parts of the standard accessories, the DP0021A accessories kit can be ordered and includes the same items shown in Figure 2. Many of these accessories can also be ordered individually (refer to the Ordering Information table near the end of this document). 

Not included as standard accessories, nor included in the DP0021A accessory kit, are the following four optional accessories shown in Figure 4.

The DP0021A-009 automotive accessory kit makes it easy to probe automotive differential serial buses, such as CAN, CAN FD, and FlexRay, in the prototype/development environment where sub-DB9 bus connectors are commonly used. Pin 7 of sub-DB9 connector is designated as the high-side signal of the differential bus, while pin 2 is designated as the low-side of the differential bus. Testing differential signals with rise/fall times faster than 5.0 ns should be avoided for optimum pulse response.

The DP0020A deskew and performance verification kit includes various SMA-to-BNC adapters and a deskew board with header pins (compatible with the socketed Y-lead pair adapter) that can be used to deskew multiple probes relative to a single timing reference point. The deskew board can also be used to verify performance characteristics including bandwidth, rise/fall times, and pulse response. Refer to the User’s Guide for more details.
