Measure insertion loss, gain, return loss, SWR, and power quickly and accurately with either the 8757C or 8757E Scalar Network Analyzers.  With high-performance detectors and directional bridges, and a companion HP source and digital plotter, the 8757C and 8757E become the basis of a complete measurement system with superb performance.

For an economical measurement solution, choose the 8757E Scalar Network Analyzer.  The 8757E features three detector inputs and two 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 8757E includes a user-friendly interface, and menu-driven, direct-access softkeys, which simplify its operation.

When your application demands maximum system versatility, choose the 8757C Scalar Network Analyzer.  It offers all of the performance of the 8757E, plus more features, limit testing, external disk save/recall, 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.

You can conveniently obtain a 20 GHz or 40 GHz coaxial measurement system by ordering the 8757XA (10 MHz to 20 GHz) or 8757XB (10 MHz to 40 GHz) scalar measurement system.  Or, you can configure your own system to 50 GHz in coax or 110 GHz in waveguide.

The 8350B sweep oscillator family offers the benefits of a modular system with choices in source frequency range and output power.  When testing narrowband, frequency-selective devices, chose a synthesized sweeper from the 8360 series or an 8340B or 8341B.  The 8360 series, 8340B, and 8341B provide excellent frequency stability and up to 1 Hz frequency resolution.

Minimize transmission measurement uncertainty by using detectors with an unrivaled match (85025E: >25 dB return loss to 25 GHz).   Maximize your reflection measurement accuracy with high directivity directional bridges (85027A,B, D: >40 dB to 20 GHz, 85027D: >25 dB to 50 GHz).  The 8757C/E are compatible with a broad line of high-performance detectors, directional bridges, and other accessories that help reduce your measurement errors.
