GEN vs TriTab Calc

GEN-B is a professional broadcast signal generator and display analysis tool designed for broadcast engineers, AV professionals, system integrators, technicians, and anyone who needs reliable video reference signals for testing, troubleshooting, and display evaluation. Built for portability and real-world workflows, GEN-B turns your device into a powerful signal generation and analysis platform capable of producing high-quality video references while providing practical display analysis tools. VIDEO REFERENCES GEN-B includes a comprehensive library of professional video reference signals designed to evaluate displays, video paths, routing systems, converters, switchers, processors, and monitoring equipment. Features include: • Professional test patterns • Video reference clips • Multiple video formats • Multiple frame rates • Geometry references • Grayscale references • Color references • Luma references • Gamma evaluation patterns • Resolution and focus references SIGNAL QUALITY GEN-B was developed with signal quality as a primary objective. The application provides high-quality video references suitable for professional evaluation workflows, including progressive and interlaced formats across multiple frame rates. Selected reference content supports advanced color reproduction, up to 12-bit video precision, and 4:4:4 chroma sampling, helping preserve fine image detail, color fidelity, and signal accuracy throughout the testing process. DISPLAY ANALYSIS GEN-B goes beyond traditional signal generation by incorporating display analysis capabilities. Using RasterScope Analysis and SWEEP technology, GEN-B can evaluate display behavior using generated reference signals and mathematical analysis techniques. Analysis functions help users better understand: • Active display area • Aspect ratio behavior • Image positioning • Display utilization • Side matte detection • Signal-to-display mapping SWEEP TECHNOLOGY At the core of GEN-B’s analysis system is a programmable RasterScope White Box Scanner. The scanner moves through the generated raster while mathematical analysis is used to interpret positional behavior and produce meaningful display evaluation information. Rather than relying only on assumptions, GEN-B generates a known reference signal and analyzes how that signal is represented on the connected display. This approach provides practical engineering insight using a portable mobile platform. TROUBLESHOOTING GEN-B was created to assist with real-world troubleshooting scenarios. Use GEN-B to: • Verify display operation • Evaluate video paths • Test display scaling behavior • Identify aspect ratio issues • Validate system performance • Troubleshoot signal routing problems • Confirm display response to known reference signals FLEXIBLE CONNECTIVITY GEN-B supports multiple external display workflows, allowing users to work in a variety of environments. Supported workflows include: • Direct external display output through compatible adapters and cables • USB-C display connections where supported • DisplayPort-compatible workflows • Wireless Output using Apple Screen Mirroring when available When using direct external display connections, additional analysis features such as RasterScope Analysis and SWEEP may be available depending on the connected hardware. RasterScope Analysis and SWEEP Analysis require direct output verification and are not available through Screen Mirroring, since mirroring may scale, composite, or reinterpret the image before it reaches the display. A TOOL DESIGNED BY ENGINEERS GEN-B was designed from an engineering perspective. The application combines signal generation, display analysis, mathematical modeling, and troubleshooting tools into a portable solution that remains simple to operate. Generate known reference signals. Analyze real-world display behavior. Transform observations into meaningful engineering information. GEN-B by Precision Broadcast Engineering.

A three-tab calculator that lets you keep multiple calculations going at the same time. The A, B, and C tabs each work as an independent calculator. Switch between them without losing your current expression or result. Use A for the pre-tax price, B for the tax-inclusive total, and C for the discounted price—all without writing down intermediate numbers or clearing your work. One purchase unlocks everything. No ads, no in-app purchases, no subscriptions. ■ Running Total as You Type The answer so far appears in small text below your expression, so you can check a running total before you press "=". ■ Three Independent Calculators Switch between A, B, and C with one tap. Each tab keeps its own expression and result, so you can work on three calculations in parallel. ■ Compare All Three See the total of all three tabs and the difference between the highest and lowest at a glance. ■ Tax In and Out Add tax with one tap, or work back from a tax-inclusive price to the pre-tax amount. Set any tax rate in Settings. ■ Split the Bill Enter a total and the number of people to get the amount per person, with optional rounding up. ■ History, Copy and Undo Each tab keeps its own history. Tap an entry to copy its result. Tap the display to copy or paste, touch and hold to clear. Undo and redo are supported. ■ Essential Calculator Functions Basic arithmetic plus square root (√), square (x²), percentages (%), sign change (±), parentheses, and a 00 key. ■ Easy on the Eyes Choose from four themes—Pastel, High contrast, Dark, and Night—and turn on Large text when you need it. ■ Four Languages English, Japanese, Simplified Chinese, and Traditional Chinese. The app follows your device language automatically. ■ Perfect For • Checking estimates and invoices • Comparing pre-tax, tax-inclusive, and discounted prices • Calculating sales tax and shopping discounts • Splitting bills and calculating per-person costs • Comparing unit prices • Adding up inventory and quantities ■ Privacy Your calculation history and settings are stored only on your device. No account is needed, and the app does not collect personal information or send your data to external servers.
