The 6820A Microwave Scalar Analyzers for fast and accurate testing in field and factory.
The synthesized source has low phase noise and 1 Hz frequency resolution. VCOs are used for frequencies above 3 GHz and an integrated RF synthesizer for the 1 MHz to 3 GHz range. Internal filtering results in excellent harmonic performance of <-50 dBc (70 MHz to 24 GHz) for improved scalar measurement accuracy. Optional step attenuators are available to set low output powers for amplifier or receiver testing. In CW mode the source can be used for local oscillator substitution. A power sweep is provided for amplifier gain compression testing. External FM can be applied by connecting an AF generator to the rear panel. The internal modualtion option provides frequency modulation of the source or pulse patterns for internal or external pulse modulators. The internal pulse modulator option allows either an external pulse generator to be connected via a rear panel BNC connector or uses the pulse patterns available from the internal modulation option. When used with the scalar analyzer the source provides a swept synthesized output for frequency characterization of components and systems.
The three-input scalar analyzer provides network characterization of components and systems. Simultaneous measurement of insertion and return loss are displayed on the 6820 color screen. Excellent measurement accuracy is assured by the use of EEPROM-corrected detectors. Each detector is individually characterized for linearity and frequency response to provide a measurement accuracy close to that achieved with a power sensor. A range of autotesters with high directivity is available for return loss measurements.
A large TFT color display is fitted to the 6820A displaying up to four measurements on two channels. Scalar measurements can be displayed simultaneously on independent channels.
Up to eight markers are available. The marker menus provide the tools that are most commonly used in each of the measurement modes. In scalar mode markers automatically calculate peak to peak ripple, N-dB bandwidth, -1 dB bandwidth and find maximum and minimum signal levels. This simplifies device characterization and reduces test time. For fault location measurements the next peak left/right feature identifies the position and magnitude of each of the discontinuities along the transmission line. The peak find softkey quickly locates the biggest discontinuity on the line.
