The Teledyne LeCroy DH Series 8 to 30 GHz differential probes offer a combination of bandwidth, input range, and offset capability to meet any high-speed probing requirement from debugging serial data interfaces to validating DDR memory systems. DH Series probes provide excellent loading characteristics and are calibrated with a custom 'tuned' frequency response. Ultra-low loading and flat frequency response ensure accurate measurements.

Two 30 GHz solder-in tips let you choose a 3.5 Vpp input range for general-purpose applications, or high sensitivity with exceptionally low noise. Also available are a 1 m long 16 GHz high-temperature solder-in 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 among any probe in the series, providing maximum flexibility in the lab. Each tip contains its own identification and calibration data for accurate signal reproduction and excellent ease of use.

The 30 GHz DH Series solder-in tips are very small, enabling access to signals on tightly packed circuit boards; the 9-inch lead length helps reach difficult-to-probe points. The standard DH-SI solder-in tip has a 3.5 Vpp input range and is well suited for DDR memory and other general-purpose high-speed serial signal applications. For smaller signals where noise performance is critical, the DH-SI-HS high-sensitivity solder-in tip has a 2.0 Vpp input range and excellent noise performance.

For tests that require placing the device in an environmental chamber, the DH-HITEMP tip can separate the solder-in probe tip from the probe amplifier by up to 1 m. This tip has 16 GHz bandwidth, a 3.5 Vpp input range, and an operating temperature range of -40°C to +125°C, making it well suited for environmental testing of various high-speed devices.

Where fast access to multiple test points is critical, the DH-PT browser tip provides 16 GHz bandwidth in a convenient 'pencil' form factor. The included free-hand probe stand enables simple hands-free browsing.

CrossSync PHY technology enables waveforms from Teledyne LeCroy oscilloscopes and traces from protocol analyzers to be displayed simultaneously, achieving full time correlation of electrical and protocol information. Through a series of CrossSync PHY-enabled interposers and using special DH-CSPHY probe tips, DH series probes can be connected directly to high-speed signal lines.

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

Mixed-signal flexibility

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