        Overview Manuals Analog Inputs Sampling & Memory Trigger & Timing Host Integration

        Features:

        • Digitizes two analog channels simultaneously at up to 100 MS/s with 14-bit resolution.
        • Combines 100 MHz bandwidth with selectable impedance, coupling, and input ranges.
        • Stores waveform records in onboard channel memory before PCI transfer to the host.
        National Instruments PCI-5122 converts two front-panel analog signals into time-aligned digital records for computer-based measurements.

        The input path conditions impedance, coupling, range, and bandwidth before the two converters sample the waveforms.

        Trigger, clock, memory, and PCI-transfer functions determine when a record starts, how long it is retained, and when it reaches the host.

        The National Instruments PCI-5122 Two-Channel 100 MHz PCI Digitizer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        National Instruments PCI-5122 Two-Channel 100 MHz PCI Digitizer Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Front-end signal conditioning

        • Channels: Two BNC inputs are sampled by separate converters at the same time.
        • Termination: The front end selects 50 ohm or 1 megohm input impedance.
        • Coupling: AC or DC coupling is applied before analog-to-digital conversion.
        • Range: Selectable full-scale ranges match the converter to the connected waveform.

        Record acquisition path

        • Conversion: Fourteen-bit samples are produced at real-time rates up to 100 MS/s.
        • Bandwidth: The analog path supports signals within a 100 MHz bandwidth.
        • Memory: Each channel writes acquired samples to its allocated onboard memory.
        • Transfer: Completed records move from channel memory to the host through the PCI bus.

        Acquisition synchronization

        • Trigger input: Trigger circuitry starts an acquisition when the configured source meets its condition.
        • Reference clock: Clock connectors allow supported timing relationships with external equipment.
        • Multi-device timing: NI-TClk coordinates supported NI digitizers when channels span more than one device.
        • Rearm: Record and trigger settings determine how the device proceeds to the next acquisition.

        PCI measurement workflow

        • Driver: NI-SCOPE supplies the programming interface for device configuration and waveform transfer.
        • Configuration: The host sets ranges, coupling, sample rate, record length, and trigger conditions.
        • Calibration: Self-calibration corrects gain, offset, frequency-response, trigger, and timing errors.
        • Cooling: Active airflow across the full-length PCI card is required inside the host chassis.
        Description
        National Instruments PCI-5122 is a two-channel, 14-bit waveform digitizer for a host computer's PCI bus. Each analog input is sampled at as much as 100 MS/s across a 100 MHz bandwidth, and the resulting records are transferred to measurement software for display and analysis.

        Both input channels on National Instruments PCI-5122 are sampled simultaneously rather than through one shared converter. Selectable 50 ohm or 1 megohm input paths, AC or DC coupling, and multiple voltage ranges adapt the front end to the connected signal before conversion.

        Acquired samples on National Instruments PCI-5122 enter channel memory before the PCI interface moves them to the host. The installed memory option therefore sets the record depth available per channel without changing the 100 MS/s real-time sampling limit.

        Trigger and timing connectors on National Instruments PCI-5122 coordinate acquisition start and clock relationships with the measured event or another supported digitizer. NI-SCOPE supplies the software interface used to configure channels, triggering, records, and self-calibration from the host application.

        Technical notes
        PCI-5122 is the full-length PCI model; PXI-5122 and PXIe-5122 have different mechanics and must not be used for its dimensions or slot requirements.

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What does National Instruments PCI-5122 measure?
        National Instruments PCI-5122 converts two analog waveforms into 14-bit digital records for host-based time- and frequency-domain analysis.
        Are both channels on National Instruments PCI-5122 sampled at the same time?
        Yes. National Instruments PCI-5122 uses two simultaneously sampled input channels, preserving their relative timing within the acquisition.
        Which input termination should be selected on National Instruments PCI-5122?
        Select the 50 ohm or 1 megohm path on National Instruments PCI-5122 to match the source and cable system before choosing the voltage range.
        How does onboard memory affect National Instruments PCI-5122?
        The installed memory option determines how many samples National Instruments PCI-5122 can retain per channel before records are transferred across PCI.
        Which software controls National Instruments PCI-5122?
        National Instruments PCI-5122 is configured through the NI-SCOPE driver, which exposes channel, trigger, record, timing, and calibration functions.
        Can a PXIe-5122 mechanical drawing be used for National Instruments PCI-5122?
        No. National Instruments PCI-5122 is a full-length PCI card and has different dimensions and slot requirements from PXI or PXI Express versions.
