Keysight (formerly Agilent T&M) 8757C 10 MHz to 40 GHz Network Analyzer
The Keysight 8757C is one of our used Scalar Network Analyzers with a bandwidth of 10 MHz to 40 GHz. With high-performance detectors and directional bridges, and a companion HP source and digital plotter, the Hp 8757C and HP 8757E become the basis of a complete measurement system with superb performance.
The HP 8757C Scalar Analyzer makes swept microwave and millimeter-wave component measurements over the 10 MHz to 110 GHz frequency range with the appropriate detectors and directional bridge. The HP 8757C can measure return loss, SWR, insertion loss, power, and voltage, in either a CW or a swept trace data format. The raster display provides high resolution for viewing measurements.
Eight CRT attributes, such as the grid, the measurement traces for each channel, and the labels are shown in various factory-defined colors. The hue, saturation, and color intensity are adjustable for each of these CRT attributes. The analyzer can drive both the internal display and one external monitor simultaneously. Color or monochrome monitors can be used, provided that they are compatible with the scan rate and video levels of the analyzer.
The 8757C is locally operated by front panel controls and by menu selection using softkeys adjacent to the CRT. The analyzer is programmable over the HP-IB. On-screen graphics can be generated using a subset of HP-GL.
The 8757C uses either AC or DC detection techniques in conjunction with its detectors. In AC detection, an RF or microwave signal is amplitude modulated with a 27.778 kHz square wave, providing the stimulus to the device under test. The output signal from the DUT is then detected by a compatible detector, and the analyzer filters, digitizes, and displays the response on the CRT. A 27.778 kHz modulation signal is available from the rear panel of the analyzer to drive an external modulator for a source without internal amplitude modulation capability. In DC detection, an unmodulated CW signal provides the stimulus to the DUT. This signal is rectified by the detector and then transformed into an AC detectable signal. The transformation is accomplished by the chopping and sampling circuitry of the detector. The rectified signal is chopped at 27.778 kHz and made to resemble a square wave.
