Marconi 6200A Series Test Set
6200A Series
RF and Microwave Test Set


PURPOSE AND FEATURES OF EQUIPMENT Introduction The 6200A Series RF and Microwave Test Sets are portable microwave measurement instruments, which integrate a synthesized sweep Generator, a four input scalar Analyzer, frequency Counter and a power meter into a single compact case. Four versions are available: the 6201A covers 10 MHz to 8 GHz, the 6200A covers 10 MHz to 20 GHz, the 6203A covers 10 MHz to 26.5 GHz and the 6204A has coverage to 46 GHz. The 6202A covers 10 MHz to 2 GHz, and is especially suitable for users working exclusively in the RF band. Whereas the other instruments are called Microwave Test Sets, the 6202A is an RF Test Set. Throughout this and other manuals, however, the series of instruments will be referred to collectively as Microwave Test Sets (MTS). A 70 dB step attenuator option is available for all versions of the MTS, which provides Synthesizer outputs over a wide amplitude range. The 6210 Reflection Analyzer adapter can be fitted to the MTS, which enables the instrument to display the complex reflection coefficient at the input of a device, and also the time domain response. The small size, integrated functions and ease of use of the MTS make the system ideal for development and production testing, installation and commissioning and field service applications. Integrating many functions into one unit not only provides convenience of operation, it also enables a number of specialized measurements to be made with ease. Typical applications for the MTS are: • Measurement of insertion loss and return loss of passive components. - Gain, gain compression and return loss of active components. • Power and frequency measurements. • Measurements on mixers and VCOs. • Location of faults in waveguide and coaxial transmission lines is possible using the Fault Location facility. This utilities advanced processing techniques to improve distance and magnitude accuracy and reduce measurement uncertainty. Main Features The MTS uses a fully synthesized frequency source. The swept signal it provides combines the speed and convenience of an analogue sweep Generator with the precision of a synthesized sweep. High frequency stability and a resolution of 1 Hz ensures that even narrow filters can be measured with accuracy and confidence. Power level is settable over a 40 dB range with a maximum guaranteed levelled power of +7 dBm. With the step attenuator option, amplitudes down to -90 dBm may be set for the characterization of amplifiers and other active devices. Self calibration of the synthesizer's power and frequency is possible using the integral power meter and frequency Counter of the MTS. Two user calibration stores can be used to perform power calibrations over a limited frequency range. The four input scalar Analyzer has typically 85 dB dynamic range and a high resolution color display. As well as the conventional 10x10 graticule two separate 10x10 graticules can be selected. Two display channels, each capable of displaying up to two swept measurements are provided. The channels may be coupled together for the simultaneous update of up to four traces, or they can be uncoupled so that each channel can display a different frequency range, allowing simultaneous display of pass-band and stop-band characteristics, for example. The power meter has a high dynamic range (-70 dBm to +35 dBm) and wide frequency coverage (30 kHz to 40 GHz). One input of the scalar Analyzer can be configured to be a power sensor input, and the measured power level is displayed as a digital readout when the readout mode is selected. A wide range of power sensors is available. Power sensors can be calibrated using the 50 MHz internal Calibrator output provided on the front panel. The frequency Counter measures frequency from 10 MHz to 20 GHz (6200A and 6201 A), 10 MHz to 26.5 GHz (6203A and 6204A) or 10 MHz to 2 GHz (6202A). A digital readout of the frequency can be displayed when the readout mode is selected. In the swept mode, the vertical axis can be set to record the frequency of a device under test as the voltage stimulus provided by the programmable voltage/current output is swept, a typical example being automatic VCO characterization.
