Agilent/Keysight 8757E

The Agilent/Keysight 8757E is a scalar network analyzer delivering precise measurement of transmission and reflection characteristics across RF and microwave frequencies. It characterizes filters, amplifiers, cables, and other components in development, manufacturing, and quality control settings.

– Technical Specifications

Frequency Coverage: 10 MHz to 50 GHz in coaxial systems; up to 110 GHz in waveguide systems. Dynamic range of 75 dB enables detection of weak signals across wide amplitude spans.

Measurement Parameters: Insertion loss, gain, return loss, standing wave ratio (SWR), and power. Three detector inputs feed two independent display channels, supporting simultaneous ratioed or non-ratioed measurements. Detection operates in AC (square wave modulated) or DC modes.

Sweep Performance: Binary format delivers 30 ms for 401-point traces and 7 ms for single-point measurements. ASCII format returns 500 ms and 10 ms respectively.

– Key Features

• Adaptive normalization for baseline correction and reference tracking
• Cursor search functions: maximum, minimum, n dB, and bandwidth identification
• 40 dB directivity bridges minimize port mismatch effects
• Power measurement accuracy through optional internal calibrator and precision detectors
• All front panel functions programmable except power on/off
• Data transfer as ASCII strings or 16-bit integers
• Compatible with HP 8757A/C scalar analyzer programming codes
• Monochrome display with optional LCD upgrade kit

– Typical Applications

Component characterization in R&D and production environments. Filter insertion loss and return loss verification. Amplifier gain and noise figure measurement. Cable and transmission line evaluation. System-level RF diagnostics where scalar response suffices.

– Compatibility & Integration

Works with compatible RF and microwave sources and printers. Detector compatibility includes HP Agilent 85025B, 85025D, 85025A, and 11664E models. Optional Mil-Std 45662A calibration with test data available.
