The SDRplay RSPdx-R2 is a wideband full featured single-tuner 14-bit SDR receiver which covers the entire RF spectrum from 1 kHz to 2 GHz giving up to 10 MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200 MHz. The RSPdx-R2 is an enhanced version of the RSPdx with further design improvements for use at frequencies below 2 MHz. Housed in a strong steel case, in addition to the functionality of the RSP1B, the RSPdx-R2 provides three software selectable antenna inputs and an external clock input. It offers excellent performance through HF and VHF frequencies all the way up to 2 GHz. The RSPdx-R2 also supports an "HDR mode" optimised for the demanding radio reception conditions below 2 MHz. The RSPdx-R2, when used in conjunction with SDRplay’s own software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2 MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. Features Covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps Receive, monitor and record up to 10 MHz of spectrum at a time Significantly improved noise performance below 1 MHz (i.e. for some MF, LF and below) Improved dynamic range below 2 MHz both in tuner mode and HDR mode HDR mode below 2 MHz giving overall dynamic range and selectivity advantages Software selectable choice of 3 antenna ports External clock input for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy Excellent dynamic range for challenging reception conditions Free use of Windows-based SDRuno software (check website for versions supported) Free use of SDRconnect SDR and server software for Windows, MacOS and Linux (Check website for versions supported) Multiplatform driver and API support including Windows, Linux, Mac and Raspberry Pi 4/5 Strong and growing software support network Calibrated S meter/RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability) Documented API provided to allow demodulator or application development on multiple platforms Applications (Amateur) Shortwave radio listening Broadcast DXing (AM/FM/TV) Panadaptor Aircraft (ADS-B and ATC) Slow Scan TV Multi-amateur band monitoring WSPR & digital modes Weather fax (HF and satellite) Satellite monitoring Geostationary environmental satellites Trunked radio Utility and emergency service monitoring Fast and effective antenna comparison Applications (Industrial) Spectrum Analyser Surveillance Wireless microphone monitoring RF surveying IoT receiver chain Signal logging RFI/EMC detection Broadcast integrity monitoring Spectrum monitoring Power measurement Applications (Educational/Scientific) Teaching Receiver design Radio astronomy Passive radar Ionosonde Spectrum analyser Receiver for IoT sensor projects Antenna research Specifications Frequency Range 1 kHz – 2 GHz Antenna Connector SMA Antenna Impedance 50 Ohms Current Consumption (Typical) 190 mA @ >60 MHz (excl.

The set of magnets and spring clips is designed for use with the AxiDraw magnetic easel boards for letter/A4 and tabloid/A3 sizes, but can be used with almost any magnetic surface. The set includes a pair of special spring clips with magnetic bases, as well as six skinny magnets for holding down paper. The two special spring clips each have two curved tines that apply gentle pressure to your paper. They allow you to slide paper directly in and out, quickly and easily, without touching any magnets, clips, or tape. They have a long reach to be positioned behind the rulers on our magnetic easels. Magnetic bases allow you to position them where needed. Two of these spring clips provide just enough pressure to keep a sheet of paper steady while you write or draw on it. This set also includes six cylindrical magnets, 4 mm in diameter and 10 mm tall, which are easy to position and firmly hold paper. The tall aspect ratio makes them particularly easy to grasp (unlike disc magnets). Perhaps more importantly, they tend to yield and tip over if hit by an errant pen tip, rather than holding so fast as to damage your pen or move your paper.

This is the standard AxiDraw pen clip that is included with current-generation AxiDraw V3 family plotters. It fits pens and other instruments up to 5/8' (16 mm) in diameter. It includes a black nylon 8-32 thumbscrew for holding the pen in place, as well as spare mounting screws. You may wish to get this as a replacement, as a spare, or to have multiple pen clips for custom applications. Compatibility The pen clip is compatible only with AxiDraw V3 family pen plotters that mount the pen on a 2-hole vertical slide. This includes all AxiDraw SE/A3, AxiDraw V3/A3, AxiDraw V3 XLX, AxiDraw MiniKit, and all AxiDraw V3 units manufactured after February 2017.

The AxiDraw SE/A3 has the same extended plotting area as the AxiDraw V3/A3. In place of the central extrusion that makes up the body of that machine, the AxiDraw SE/A3 has a central beam that is CNC machined from a solid billet of 6061-T6 aluminum, and then anodized to a sleek black finish.This heavy, rigid structure – it's a solid block of metal! – provides dramatically better straightness and stiffness, even compared to the already-stiff AxiDraw V3/A3. This design adds mass exactly where you want it: to the non-moving base that forms the X-axis of the machine. In order to keep the weight light where it matters, the moving Y-axis of the AxiDraw SE/A3 uses the same stiff and light custom aluminum extrusion that we use on the AxiDraw V3/A3.Beyond this, the central beam and X-axis of the AxiDraw SE/A3 feature an all-new geometry for the rolling wheels, which provides more stable and uniform motion along the axis.Getting StartedThe AxiDraw comes fully assembled, tested, and ready to use, right out of the box. A universal-input plug-in power supply is included with the AxiDraw, as is a USB cable, and an optional paper-holding easel. Assuming that you've installed the software first, you can be up and plotting within minutes of opening the box. Our comprehensive PDF user guide walks you through every step of the process.To operate AxiDraw, you will need a reasonably modern computer with an available USB port (Mac, Windows or Linux), plus internet access to download necessary software. Pens and paper are not included. (You can use your own; AxiDraw does not require proprietary pens or paper.)AxiDraw is normally controlled through a set of extensions to Inkscape, the excellent, popular and free vector graphics program. Basic operation is much like that of a printer driver: you import or make a drawing in Inkscape, and use the extensions to plot your text or artwork. It's all handled through a straightforward graphical user interface, and works cleanly on Mac, Windows and Linux.SpecificationsPerformance Usable pen travel (inches): 16.93 × 11.69 inches Usable pen travel (millimeters): 430 × 297 mm Vertical pen travel: 0.7 inch (17 mm) Maximum XY travel speed: 15 inches (38 cm) per second Native XY resolution: 2032 steps per inch (80 steps per mm) Reproducibility (XY): Typically better than 0.005 inches (0.1 mm) at low speeds. Physical Major structural components are machined and/or folded aluminum. Holds pens and other drawing instruments up to 1' (25.4 mm) diameter.

Comprehensive user guide available for download Driver software software free to download and open source Internet access is required to download software. Additionally, AxiDraw Merge software available at no cost to AxiDraw owners. Programming interfaces Note: Programming is not required to use the AxiDraw. Stand-alone command line interface (CLI) Available AxiDraw Python API RESTful API available for full machine control, stand-alone or accessible by running RoboPaint in the background. Simplified 'GET-only' API available as well, for use in programming environments (such as Scratch, Snap) that permit only retrieval of URLs.
