content: HpW is proud to announce the new version 3.4 of the uniqueFFT-based analysis software HpW Works. The new release includes animproved lookout and several new display options, like Real Time display,THD, THD+N, Dynamic range (DR), SNR and level calculations, phase view,min/max band view, which can be displayed on each spectrum. The analysisdata showing more detailed information is presented on a separatedata window. Using dual channels, the phase relationship is also shown.Analyzing signals, in the labor, development or music studio is thetarget use of HpW Works. HpW delivers high-end measurement for anastonishing low price. The full system includes a FFT-software plussignal generator, operating with any PC sound card or digital I/O hardware.For the input and output section various plugin modules are availableand custom plugin build.Main application features=========================o Design pattern implementation (modal design)o SMP CPU usage with multi threading implementationo SDI Main & Client Window implementationo Each client SDI Window may dock and stay attached to the main application windowo Dynamically loaded Measurement Instance frame worko Various user selectable theme colors for all HpW-Works dock and tool barso Configuration store in the MS Windows registryo Preset applications with export and import (exchange with PC(s) or users) to file functionso Status bar: Memory channel count, dump and dump tree stateo Common used application folder setup dialogo Common file dump feature (sample data, various spectrum data, picture of spectrum)o Common file dump tree feature (sample data, various spectrum data, picture of spectrum)o Print page setup for normal and landscapeo Use of a common "ProgramData" folder for file read & write operation(ProgramData\HpW-Software\HpW-Works)o Uninstallation using the MS Windows system "Control Panel \ Add remove Software"o Application protection using a personal USB data stick (no additional MS Windows driver required)o Clear font drawing optiono Separated installation kit for the HpW-Works Full Version and the HpW Works Evaluation VersionAmplitude Window:=================o Window with a sizable floating RMS meter toolbaro Meter scaling: dBFS, dBV, dBmV, dBuV, dBu, dBW, dBmW, dBuW, dBc, dBSPL, Volt, Watt, % FS levelso Configurable amplitude statistic data optionso Input with level / impedance / dBSPL / external gain calibrationo RMS Logger WindowTest instances==============Basic features:---------------o Internal 64/80 bit floating calculationso All spectrum windows are sizableo Multiple opened spectrum windowso Most used analysis spectrum data or each channel presented on spectrum frameo X-axis scaling: Linear, logarithm, center and custom rangeso Y-axis dB scaling range 1..400dBo Various FFT windowing functions with up to 13 terms, Flat top, BH, cosine and HFTxxo Full X/Y axis or only X axis mouse drag zooming on linear / logarithm scaleo Data measuring on spectrum using X/Y axis mouse draggingo Averaging with count optionso Spectrum with min/max spectrum history shown as band or lineo Spectrum data export & import with owner watermarkingo Spectrum header text for each channelo Cursor data toolbar: Spectrum data or grid position relatedo Re-Run spectrum calculation with current sampled datao Multiple spectrums with a description frame (history, imported, saved or min/max band)o Individual color setupo Individual data cursor setupo Printing normal, landscape, color or monochromeo Save spectrum image using current size or using custom size using bmp, jpeg, png formatFFT 2D Window (level spectrum):-------------------------------o Y-axis scaling: dBFS, dBV, dBmV, dBuV, dBu, dBc, dBSPL, dB/rtHz, Linear, Linear/rtHzo Y-axis linear scaling range nV to kVo Spectrum phase view with optional level masking optionso Spectrum data windowo Spectrum analysis detail windowPSP 2D Window (power spectrum):-------------------------------o Y-axis scaling: dBFS, dBW, dBmW, dBuW, dBV^2, dBu, dBc, dB/Hz, Linear, Linear/Hzo Y-axis linear scaling range aW to kWo Spectrum data windowo Spectrum analysis detail windowPSD 2D Window (power spectrum density):---------------------------------------o Y-axis scaling: dBFS, dBV^2, dBc, dB/Hz,o Spectrum data windowo Dual channel conjugate complex averageWave Generator:===============o Apply dither with custom level and distributiono Channel muting and invertingo Auto restart option after closing any setup dialogo Sample rate and interface capability check dialogSignals:--------o Static signal (DC)o Sine (coherent / non-coherent) with phase optiono Sine Full scale (coherent / non-coherent)o Sine & Harmonic with up to 64 individual harmonics (level & phase)o Sine & Harmonic with export and import (exchange) functionso Multi Sine Waves with up to 512 individual sine waves (frequency & level & phase)o Multi Sine with export and import (exchange) functionso IM signals: SMPTE & DIN waves etc.o Jitter test signal (fs/4 or fs/8 with LSB toggle) andsymmetric J-Test signal (J.
