Differential Probing Solutions
DA18000 / D13000PS / D11000PS
High-Performance
Probing Solution for
SDA 9000, SDA 11000, SDA 13000,
and SDA 18000
The D13000PS/D11000PS extends the full signal acquisition performance of the SDA 13000, SDA 11000 and SDA 9000 to the probe tips. With 13/11 GHz system bandwidth, the probe enables direct measurement of high-speed serial data streams up to 6.25 Gb/s.
When used to acquire input signals for the SDA 13000, SDA 11000, SDA 9000, or SDA 18000, the D13000PS/D11000PS provides unprecedented waveform fidelity, even with signals at higher serial data rates. Each probe utilizes third generation response compensation calibration, the most advanced in use today, to provide optimal system response.
The D13000PS/D11000PS provides both direct Solder-In and cabled SMAconnector interconnect lead assemblies. The D13000PS also provides SMP cables for additional cabling options. Each interconnect lead comes with a dedicated probe amplifier module that has calibration data optimized for the respective lead. This eliminates the performance compromise of using a single calibration for multiple lead types.

Probe System
The DA18000 Differential
Amplifier
The DA18000 Differential Amplifier is a very high bandwidth DC coupled differential amplifier with a true 100 Ω balanced input. It features high common mode rejection, low noise, and is designed to be used exclusively with the SDA 18000 Serial Data Analyzer. The amplifier has unity gain, to maximize the signal to noise performance when used with the lower amplitude signal voltages common in higher data rate systems.
The DA18000 is supplied with a short pair of input cables which are matched to an electrical propagation length of 2.5 ps. Use of the DA18000 with these cables eliminates the need to deskew and calibrate input channels for differential match, a problem encountered when acquiring differential signals with two oscilloscope channels connected with long cables.
The DA18000 differential amplifier utilizes third generation digital response equalization, the same calibration method used in LeCroy’s award winning high bandwidth probes. This provides the most accurate magnitude and phase response, assuring the high fidelity eye pattern measurements.
