Agilent / HP / Keysight 8757C
8757C Scalar Network Analyzer
The Agilent/HP 8757C Scalar Network Analyzer is an instrument which measures the complex transmission and reflection characteristics of two port devices in the frequency domain.
The Agilent 8757C does this by sampling the incident signal, separating the transmitted and reflected waves, and then performing ratios that are directly related to the reflection and transmission coefficients of the two-port.
Frequency is swept to rapidly obtain amplitude and phase information over a band of frequencies of interest.
This network can provide a wealth of knowledge about a device under test (DUT), including its magnitude, phase, and group-delay response.
The 8757C is compatible with the Agilent 85025 and 85026 series detectors and the Agilent 85027 series directional bridges
The 8757C has two independent display channels that process the signals from the Agilent 85025 and 85026 detectors, and the Agilent 85027 series directional bridges for logarithmic display, in single channel or ratio mode.
The 8757C provides a linear moving average of adjacent data points. The smoothing aperture defines the trace width (number of data points) to be averaged, and ranges from 0.1% to 20% of the trace width. 2, 4, 8, 16, 32, 64, 128, or 256 successive traces can be averaged.
The 8757C provides saving or recalling of up to 9 complete front panel states. If the source (Agilent 8360 or 8370 series) is connected to the 8757C system interface, the front panel states of both the network analyzer and source are saved.
The Agilent 8360 series and Agilent 8370 series synthesized sweeper sources are specifically made to complement the Agilent 8757C system.
The Agilent 8757C is able to display start, stop and marker frequencies, save and recall front panel states of both the sweeper and the scalar analyzer, preset both instruments simultaneously, and alternately sweep two different frequency or power ranges and display both simultaneously with the HP 8360 and 8370 series synthesized sweepers.
The Agilent 85027 series directional bridges are designed to operate with the Agilent 8757C in AC or DC detection modes. These bridges offer high directivity, excellent test port match, and a measurement range of up to 50 GHz in coax.
