Teledyne LeCroy’s DH series 8 to 30 GHz differential probes offer the combination of bandwidth, input range and offset capability to address any high-speed probing requirement from debugging serial data interfaces to validating DDR memory systems. DH series probes provide superior loading characteristics and are calibrated with a custom “fine-tuned” frequency response. The ultra-low loading and flat frequency response ensure accurate measurements.

Two 30 GHz solder-in leads let you choose between a 3.5 Vpp input range for general-purpose applications, or high sensitivity with exceptionally low noise. Also available are a 1-meter long 16 GHz high-temperature tip, a 16 GHz browser tip, and a QuickLink adapter for connecting mixed-signal probe tips. The same solder-in, high-temperature and QuickLink tips are compatible with all DH series probes and can be interchanged between any probes in the series for ultimate flexibility in the lab. Each tip contains its own identification and calibration data for accurate signal reproduction and superior ease of use.

The 30 GHz DH series solder-in tips are extremely small to facilitate access to signals on tightly-packed boards, with a 9-inch lead length to help reach difficult probing points. The standard DH-SI tip has a 3.5 Vpp input range, perfect for DDR memory and other general-purpose high-speed serial signal applications. For smaller signals where low noise is critical, the DH-SI-HS high-sensitivity tip has a 2.0 Vpp input range and exceptional noise performance.

For tests where the device must be placed in an environmental chamber, the DH-HITEMP tip allows the solder-in probe tip to be separated from the probe amplifier by up to 1 meter. The tip offers 16 GHz bandwidth, 3.5 Vpp input range and an operating temperature range of -40 °C to +125 °C, making it ideal for environmental testing of a wide variety of high-speed devices.

In situations where quick access to many test points is critical, the DH-PT browser tip offers 16 GHz of bandwidth in a convenient "pencil"-style form factor. An included Freehand probe holder allows simple hands-free browsing.

CrossSync PHY technology enables waveforms from Teledyne LeCroy oscilloscopes to be viewed alongside protocol analyzer traces, with complete time-correlation of electrical and protocol information. A range of CrossSync PHY enabled interposers provides direct connection for DH Series probes to high-speed signal lines using special DH-CSPHY probe tips.

The DH-QL adapter enables QuickLink solder-in probe tips to be used with any DH series probe. For embedded systems validation and debug, these tips can be used for both analog probing with the DH series probes and digital acquisition with the HDA125 high-speed digital analyzer.

When connected to a Teledyne LeCroy analog differential probe, QuickLink tips provide 8 GHz of bandwidth and a flat, well-controlled frequency response. When used with the HDA125 for digital acquisitions, they support 3 GHz bandwidth with industry-leading sensitivity. The HDA125 provides the ability to acquire and analyze DDR command bus signals and other high-speed digital buses directly alongside time-correlated analog signals on the standard oscilloscope channels.
