National Instruments 785033-01 PXI Pulse Generator

The National Instruments 785033-01 (model PXIe-1209) is a high-performance, dual-channel PXI Pulse Generator designed for precise timing applications. This fully programmable device supports pulse timing granularity as fine as 10 picoseconds at repetition rates up to 100 MHz. It offers dual independent pulse generation with comprehensive control over pulse delay, double pulse spacing, width, and period.

The NI 785033-01 features multiple operational modes that include single or continuous pulsing, single or double pulse, and burst modes ranging from 2 to over 1 billion pulses. This pulse generator operates with an internal clock frequency range from 0.1 Hz to 100 MHz along with a resolution of 0.093 Hz and an accuracy of 0.01%. The pulse output characteristics of NI 785033-01 include a voltage range from -1.5 V to 6.5 V with an output impedance of 50 Ω. The output resolution is 2 mV with an accuracy of ±(2.0% + 100 mV).

The sync out characteristics of the 785033-01 offers a time from external trigger of less than 35 ns, an output impedance of 50 Ω, and selectable amplitudes of 5 V or 6.5 V. The device supports a source or sink current of 60 mA, with a rise/fall time of 2 V/ns and software-selectable widths of 5 ns or 55 ns. In addition, it includes a programmable threshold from -5 V to +5 V with a resolution of 39 mV and an impedance of 50 Ω. It ensures precise control with an accuracy of ±(5% + 150 mV) and supports a maximum frequency of 100 MHz with a minimum pulse width of 3 ns.

The 785033-01 interfaces include front panel I/O connectors for outputs and inputs along with MCX connectors and configurable impedance. The device requires +3.3 VDC at 3A and +12 VDC at 1.6 A for operation. The device is compliant with various environmental standards that include operating at temperatures from 0°C to 55°C and altitudes up to 10,000 feet. It supports relative humidity ranges of 5 to 95% non-condensing at temperatures below 30°C. The overall weight of the unit is 0.567 kg (1.26 lbs.).
