Measure insertion loss, gain, return loss, SWR, and power quickly and accurately with the HP 8757C Scalar Network Analyzer. With high-performance detectors and directional bridges, and a companion HP source and digital plotter, the 8757C becomes the basis of a complete measurement system with superb performance. For an economical measurement solution, choose the 8757C Scalar Network Analyzer. The HP 8757C features three detector inputs and four independent display channels, allowing simultaneous ratioed or non-ratioed measurement of your device's transmission and reflection characteristics, 76 dB dynamic range (+16 to -60 dBm) for measuring high rejection devices, and a choice between AC (square wave modulated) or DC detection techniques. The internal plotter/printer buffer allows you to send your measurement data directly to a plotter and then proceed to the next measurement, typically in less than 5 seconds. The 8757C includes a user-friendly interface, and menu-driven, direct-access softkeys, which simplify its operation. This unit also features limit testing, external disk save/recall, 40 dB directivity bridges, 40 GHz in coax, 110 GHz in waveguide, and a color display. Limit testing reduces test time by letting the analyzer make quick and objective pass/fail decisions. External disk save/recall allows your measurement state to be preconfigured by an engineer or skilled specialist and then automatically recalled by production technicians. The result is reduced setup time and greater test integrity at each production station. The precision color display simplifies the separation of measurement information while providing a pleasant display for the technician.
