Agilent 8757A 60GHz Scalar Network analyzer

The Agilent 8757A is a scalar network analyzer operating from 10 MHz to 60 GHz, delivering precise magnitude measurements of RF and microwave components across insertion loss, gain, return loss, SWR, and power. With 76 dB dynamic range and 0.01 dB vertical resolution, it captures accurate characterization data critical for aerospace, defense, and telecommunications applications.

Technical Specifications

• Save and recall up to nine instrument states, including calibration and measurement data


• HP-IB (GPIB) system control interface for integration with swept sources, plotters, and printers


• Internal plotter/printer buffer accelerates measurement cycles by returning control while data outputs


• External voltage measurement via rear-panel ADC input (–10 to +10 volts)

Measurement Capabilities

• Insertion loss and gain


• Return loss


• Standing wave ratio (SWR)


• Power in dBm

Compatibility & Integration The analyzer interfaces with HP 11664 A/E detectors, HP 85025/85026 AC/DC detectors, and HP 85037 series precision detectors. Directional bridge support includes HP 85020 and 85027 series units. Swept source compatibility spans HP 8350B, HP 8340B/8341B, Agilent PSG1 (Option 007), Agilent 8360 and 8370 series. The 8757D model enables external data storage and retrieval via HP-IB disk drive interfaces.
