Keysight Technologies N1055A-54F Spec Sheet
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What is the bandwidth and channel configuration of the N1055A-54F?
The N1055A-54F is a 50 GHz, 4-channel TDR/TDT remote head module equipped with 1.85 mm female connectors. It provides industry-leading TDR resolution with a raw hardware step rise time of less than 7 ps (10 to 90%), making it well suited for accurate impedance and S-parameter measurements on high-speed designs operating at 28 Gb/s and beyond.
How fast is the TDR edge speed on the N1055A with 50 GHz bandwidth?
The N1055A with 50 GHz bandwidth delivers a transmitted TDR step rise/fall time of less than 7 ps (10 to 90%) without calibration. With TDR calibration applied, the effective edge speed becomes adjustable from 6 ps (characteristic). This fast edge speed provides the highest resolution for locating and characterizing impedance discontinuities in complex high-speed structures.
Does the N1055A support single-ended and differential TDR measurements?
Yes, the N1055A supports single-ended, differential, and common-mode TDR/TDT measurements with True-Mode and Mixed-Mode stimulus capability. The ultra-slim remote heads can be clamped together to form differential pairs with 10 mm pin-to-pin spacing. Step polarity, skew, amplitude, and repetition rate are all configurable through the FlexDCA graphical user interface.
What is the maximum S-parameter measurement frequency for the N1055A-54F?
The N1055A-54F enables calibrated S-parameter measurements from DC up to 50 GHz. S-parameters are generated in real-time within the 86100D oscilloscope using Option 202 enhanced impedance and S-parameter analysis software. Full single-ended and mixed-mode S-parameter measurements on up to 16 ports are supported, with magnitude, phase, and group delay plots displayed simultaneously.
How many TDR/TDT ports can be configured in a single 86100D mainframe?
Up to 16 TDR/TDT channels can be configured per 86100D DCA-X mainframe by installing up to four N1055A modules. This multi-channel capability minimizes cable reconnections and facilitates efficient near-end crosstalk (NEXT) and far-end crosstalk (FEXT) measurements. A 16-port system can measure NEXT and FEXT on up to four differential lanes simultaneously.
What calibration methods does the N1055A TDR module support?
The N1055A supports traditional mechanical short-open-load-thru (SOLT) calibration standards and electronic calibration (ECal) modules through a built-in wizard. The Keysight N4694A DC to 67 GHz ECal module is specifically designed for DCA-TDR applications, providing fast and accurate calibration and de-skew without the multiple manual connections required by mechanical standards.
Does the N1055A include ESD protection for the remote heads?
Yes, each N1055A remote head integrates multiple 67 GHz diode limiters to protect against electrostatic discharge (ESD) and electrical overstress (EOS). A high-speed step generator, low-noise sampler, and diode limiter are all built into a proprietary microcircuit housed within each remote head. Standard safe ESD and EOS handling practices should still be followed.
Does the N1055A support TDR fixture de-embedding?
Yes, TDR fixture de-embedding is standard in FlexDCA software revision A.05.30.xx and newer. It allows removal of the effects of fixtures, cables, or probes connected between the remote heads and the device under test using S-parameter files. FlexDCA supports both 2-port and 4-port fixtures on DUTs with up to 16 ports, and includes automatic fixture removal (AFR) for one-port and 2x-thru characterization.
