r&s®vsa video measurement system | 概览 -55体育

video measurement system vsa from rohde & schwarz combines the functions of a video analyzer, vectorscope, oscilloscope, monitor and controller (pc) in a 19" desktop. fields of applications are

• laboratory and service
• automatic test and monitoring systems
• production and quality assurance

the instrument features convenient operation as well as high measurement accuracy and speed. the compact design makes it also suitable for mobile applications. thanks to the great number of integrated functions and system interfaces the vsa is an essential tool for measurements and system applications in all fields of video. in addition to the versatile measurement capabilities provided, the modular software and hardware configuration offers sufficient capacity for future expansions.

• simultaneous computation of up to 150 different signal parameters
• automatic limit monitoring
• automatic overall measurement of all parameters
• individual measurements using extended test capabilities
• test-signal and test-location display
• standard or reference measurement for each parameter separately

• simultaneous display of up to three video signals in separate displays
• separate test input for each part display (eg components, rgb, ycbcr)
• simultaneous display of the same signal with different time scales in up to three separate windows
• displayed signal section variable in the x and y direction from approx. 200 ns to 20 ms
• digital filters for simulating signal manipulations, eg all ccir filters for insertion signal measurements
• scale automatically matched to the display
• two cursors for each window: level, peak, slope and pulse functions allow analysis of complete signal elements

• graphic display of all colour parameters of a video line in magnitude and phase
• accurate measurement of phase difference of two colour signal sub-carriers by alternate suppression of colour subcarrier reference
• permanent waveform display of video line
• automatic computation and display of all colour subcarrier amplitudes and phases when a standard colour bar signal is applied

• easy identification of selected video signal
• display of a video signal as monochrome tv picture with eight grey levels
• simultaneous display of any rollkey-selected video line of the tv picture

• comprehensive automatic test system
• control of external devices via iec/ieee bus or serial interface
• complete pc (dos win-dows) with integrated iec/ ieee-bus card
• computing and measurement functions independent of each other
• simple switch-over between measurement display and dos display
• vga colour monitor and external keyboard available as accessories
