# Keysight 86100D DCA-X Wide Bandwidth Oscilloscope Mainframe (Pre-Owned) # Keysight 86100D DCA-X Wide Bandwidth Oscilloscope Mainframe (Pre-Owned) ## Key Features At A Glance - Performs precision measurements on high-speed digital designs from 50 MBd to more than 80 GBd - Up to 16 channels with simultaneous acquisition - Modular plug-in architecture supports electrical, optical, optical/electrical, TDR, clock recovery, and precision waveform analyzer modules - Time interval accuracy of 1 ps + 1.0% of Δ time reading or 8 ps, whichever is smaller - Optional integrated Precision Timebase (PTB) for low-jitter measurements down to characteristic 90 fs at trigger frequencies above 9 GHz - Pattern lock record length up to 32 M samples in FlexDCA (pattern, channel count, and available memory dependent) - Standard Trigger (STR) or Enhanced Trigger (ETR) configurations to match application requirements - Supports a broad range of compliance and analysis software including PAM-N, jitter, S-parameter, and IEEE/OIF-CEI applications The Keysight 86100D DCA-X is a wide bandwidth oscilloscope mainframe that performs precision measurements on high-speed digital designs from 50 MBd to more than 80 GBd, with up to 16 channels acquired simultaneously. The mainframe accepts a wide range of plug-in modules covering electrical, optical, optical/electrical, TDR/TDT, clock recovery, and precision waveform analysis, making it the platform around which complete Digital Communications Analyzer solutions are built. Applications described in the datasheet include optical transceiver design and production test, electrical ASIC/FPGA/IC design and characterization, and serial bus characterization, measurement, and troubleshooting via TDR/TDT and S-parameter measurements of channels, cables, and PCBs. The DCA-X family is positioned for engineers working on eye diagram analysis, jitter analysis, PAM-N signaling, and compliance testing against published industry standards. ValueTronics International has supplied new and pre-owned test and measurement equipment to engineering teams across aerospace, telecommunications, semiconductor, and high-speed digital design since 1992. Our 86100D DCA-X inventory is housed and serviced at our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where every unit is processed, inspected, and prepared by experienced technicians before shipment. For instruments of this complexity — wide-bandwidth oscilloscope mainframes with modular electrical, optical, and precision-timebase configurations — that hands-on verification step is the difference between buying with confidence and buying from a drop-shipper. Our team can also confirm installed options, module compatibility, and software licensing before the unit ships, which is information drop-ship listings rarely provide accurately. ## Brand Heritage The 86100D DCA-X traces its lineage through one of the most respected names in electronic test and measurement. Hewlett-Packard spun off its test and measurement business as Agilent Technologies in 1999. In 2014, Agilent further separated its electronic measurement division, which became Keysight Technologies. The 86100-series digital communications analyzer platform has continued forward across all three brand identities, with the 86100D representing the current generation of the mainframe under the Keysight name. ## Accessories Supplied - USB Keyboard and mouse - 2.92 mm female-female connector saver (P/N 1250-4105) for trigger input - Nominal length jumper cable (with Option PTB, for precision timebase delay path) ## Product Core & Specifications Category Specification Value Temperature Operating 10 to +40 °C (50 to +104 °F) Non-operating –40 to +65 °C (–40 to +158 °F) Altitude Operating Up to 4,600 meters (15,000 feet) Power (max) 100/120 Vac 50/60/400 Hz With typical modules: 150 to 230 VA at 25°C 220/240 Vac 50/60 Hz 700 W maximum Weight Mainframe without modules 20.5 kg (43 lbs) Typical module 1.2 kg (2.6 lbs) Mainframe Dimensions (excluding handle) Without front connectors and rear feet 221 mm (H) x 426 mm (W) x 530 mm (D) (7 in x 16.76 in x 20.9 in) With front connectors and rear feet 234 mm (H) x 426 mm (W) x 601 mm (D) (9.23 in x 16.76 in x 23.67 in) With front cover and rear feet 234 mm (H) x 426 mm (W) x 612 mm (D) (9.23 in x 16.76 in x 24.1 in) Max Relative Humidity — 80% for temperatures up to 31 °C decreasing linearly to 50% relative humidity at 40 °C Supply Voltage Variation — Can operate with supply voltage fluctuations up to ± 10% of the nominal voltage Horizontal System (Time Base) Scale factor minimum 100 fs/div Scale factor maximum 1 s/div (250 ns/div with pattern lock) Delay minimum 24 ns (40.1 ns default with pattern lock, 24 ns min) Delay maximum 1000 screen diameters or 10 s whichever is smaller (1000 screen diameters or 25.401 μs whichever is smaller with pattern lock) Time interval accuracy 1 ps + 1.0% of Δ time reading or 8 ps, whichever is smaller Time interval resolution ≤ (screen diameter)/(record length) or 62.5 fs, whichever is larger Jitter Mode Time interval accuracy 1 ps (jitter mode operation) Vertical System (Channels) Number of channels 16 (simultaneous acquisition) Vertical resolution (54xxx, 83xxx, 86xxx) 14 bit A/D converter (16 or more bits with averaging) Vertical resolution (N10xx) 16 bit A/D converter Record length (Legacy UI) 16 to 16 K samples Record length (FlexDCA with pattern lock) 16 up to 32 M samples Computer System CPU Intel Core i5 3550S CPU at 3.0 GHz Mass storage 150 GB internal hard drive (default) or 80 GB removable hard drive (Option 090) Operating system Microsoft Windows 7 embedded standard (64 bit) Display Display area 210.4 mm x 157.8 mm (10.4 inch diagonal color active matrix LCD) Resolution 1024 x 768 pixels Persistence modes Gray scale, color grade, variable, infinite Front Panel I/O Cal output BNC (female) and test clip, banana plug Trigger input 2.92 mm USB Three low-power USB 2.0 ports; 5.00 ± 0.25 V; 100 mA each Precision timebase input (Option PTB only) 2.92 mm Rear Panel I/O Gated trigger input TTL compatible Video output VGA, full color, 15 pin D-sub (female) GPIB Fully programmable, complies with IEEE 488.2 (optional, order 86100D-GPI) RS-232 9 pin D-sub (male) USB Four USB 2.0 ports; 5.00 ± 0.25 V; 500 mA each Precision timebase delay path (Option PTB only) Two female SMA connectors, nominal length jumper cable included **Important:** Option ETR is recommended when using a DCA module equipped with a rear panel trigger circuit such as the 54754A, 83496-series, or 86108-series.**Important:** Plug-in modules are sold separately and are required for the 86100D mainframe to perform measurements.
