3 / 14 page 3 Easily perform manual and automated tests One-button access makes it easy to select the four main operating modes: analyzer, generator, graph and sweep. The 5.7-inch color display provides numeric readouts as well as graphical views of analog sweeps, FFT spectra and more. For PC-based control on the bench or in a test system, the U8903A includes GPIB, LAN and USB interfaces. If your system currently uses an HP 8903B audio analyzer, the application note ‘Migrating Code from the 8903B to U8903A (5990-4135EN)’ describes compatible equivalent commands, and provides sample test programs comparing the old R2D2 codes with new U8903A SCPI commands’. Figure 4: The new U8903A audio analyzer offers numerous improvements over the widely used HP 8903B. Replace your 8903B and add next-generation capabilities For nearly two decades, the HP 8903B provided unparalleled versatility and performance in audio applications. Today, the U8903A audio analyzer builds on the legacy of the 8903B by offering faster single-point measurements (0.4 sec vs. 3.0 sec) as well as a wider frequency range, expanded performance and greater functionality (Tables 1, 2 and 3). Because the U8903A is based on the latest digital technologies, we also predict greater instrument uptime on the bench and in test systems. With the U8903A, you can configure measurements faster through its graphical user interface (GUI) and one-button selection of major operating modes. The color screen lets you view dual-parameter displays from one or two channels as well as graphical displays of sweeps, frequency spectra and more (Figure 4).
