The Tektronix 11A34V is a four-channel vertical amplifier plug-in module engineered for the 11000 and DSA600 series oscilloscopes. Optimized for video signal analysis, it delivers DC to 300 MHz bandwidth with 1.17 ns rise time and dual input impedance (1 MΩ and 75 Ω) for flexible measurement configurations.
Technical Specifications
• Bandwidth: DC to 300 MHz
• Vertical Sensitivity: 1 mV/Div to 10 V/Div in 1% increments
• Rise Time: 1.17 ns
• Input Impedance: 1 MΩ or 75 Ω (switchable)
• Maximum Input Voltage: 500 Vrms
• Calibrated DC Offset: ±1 V range with 25 µV resolution at 1 mV/div (16-bit equivalent)
• Bandwidth Limit Filters: Two selectable four-pole filters at 100 MHz and 20 MHz (24 dB/octave attenuation per channel)
– Key Features
• Four independent channels with fast overdrive recovery
• High-resolution offset control for precise baseline adjustment
• AC coupling capacitor on each input channel with passive 1 MΩ attenuators
• M474 buffer amplifier per input stage
• M377 IC for output amplification
• Non-volatile memory (Dallas Semiconductor DS1220Y) stores calibration data and instrument settings
• Integrated sample-and-hold modules for analog control voltage systems
– Typical Applications
• Video signal characterization and compliance testing
• Multi-channel analog signal acquisition and analysis
• High-frequency transient measurements requiring fast rise time
• Systems requiring switchable impedance matching for 75 Ω video circuits or standard 1 MΩ measurement paths
– Compatibility & Integration
The module plugs directly into Tektronix 11000 series oscilloscopes (11301, 11301A, 11302, 11302A, 11401, 11401A, 11402, 11402A, 11403) and DSA600 series instruments. Host oscilloscopes provide IEEE-488 (GPIB) and RS-232C interfaces for remote operation and automated test system integration. P6134(C) probes and 4906-1RA adapters are recommended for signal coupling.
