Информация:

The Model 8211 is a precise, versatile, solid-state instrument with features and performance characteristics especially suited to laboratory and industrial applications. It covers a frequency range of 2 MHz to 1J> GHz. Human engineering considerations have been emphasized in both the mechanical and electrical design of the Model 8211. The result is a modulation meter that is easy and convenient to use, despite its flexibility. Among the outstanding features: • Automatic tuning and leveling. The Model 8211 can automatically acquire the largest signal present at the RF IN connector and adjust its local Oscillator and measurement channel gain to provide a calibrated display of amplitude or frequency modulation. • Internal Calibration. The Model 8211 contains precision AM and FM calibrators that can be activated from the front panel to calibrate the modulation detectors. • Low Residual Modulation. Low modulation residuals provide excellent measurement accuracy with low noise sources. Additionally, active peaJk detectors insure exceptional baseband detection linearity so that residuals may be easily discounted for enhanced measurement accuracy. • IEEE-488 Bus Interface. The Model 8211 is supplied with an IEEE-488 Interface. This Interface allows connection to remote computers and Other instruments.
