DTDR-800 Differential TDR
- Series: TDR - Brand: Te-lead
Step rise/fall-time
The DTDR-800 is equipped with two fast inter-nal step generators providing step-signals with a 10% - 90% rise/fall-time below 800ps (typ. 650ps), corresponding to a 20% - 80% rise-time below 550ps (typ. 450ps). The use of two gen-erators enables true differential technology, which makes differential probing easy, since ground contacts are not required. Of course, ground contacts are still needed in case the fully integrated single-ended functionality is used. The voltage step of each channel amounts to 550mV under matched conditions.
Ultra low random Jitter
The DTDR-800 exhibits the best RMS-jitter per-formance in its class: lower than 3.0ps over the full temperature range.
Superior Stability over Temperature
All Sequid products undergo a temperature check from 0°C to 40°C to verify the functional-ity over the full range. The DTDR-800’s excel-lent jitter performance is minimally influenced by temperature. Amplitude variations are around only 1%. This performance is achieved without application of time consuming and re-curring error compensations.
Laboratory & Industrial
Due to its time base and temperature stability the DTDR-800 is the ideal choice not only for laboratory but also for outdoor applications. In addition, its full metal housing offers a high level of immunity to EMI and makes it well suited for industrial applications. The casing ex-hibits a small form factor and weighs below 3kg.
Software Applications
A wide range of accessories & applications are implemented or optionally available (see sec-tion 5), e.g. probes, TDR functionality and S11-parameters. The DTDR-800 comes along with a user-software (SEUNIS = Sequid Universal Measurement Software), combining all dif-ferent applications and calibrations. Software libraries (SAIL = Sequid Automation Inter-face Library) are available for controlling the device in ATE applications from many programming languages (e.g. C/C++, C#, Py-thon, LabVIEW, MATLAB). Modules for exporting the data from the Sequid soft-ware are included.
