The Tektronix 11A34 is a four-channel vertical amplifier plug-in for 11000-series and DSA600-series oscilloscopes. It delivers DC to 300 MHz bandwidth with selectable input impedance, calibrated deflection factors from 1 mV to 10 V/division, and high-resolution DC offset measurement. The unit features fast overdrive recovery, built-in bandwidth-limit filters, and TEKPROBE® input compatibility for comprehensive signal acquisition and analysis across demanding measurement applications.
Technical Specifications
• Bandwidth: DC to 300 MHz; selectable reduction to 100 MHz or 20 MHz via four-pole bandwidth-limit filters at 24 dB/octave
• Channels: Four independent channels
• Rise Time: 1.2 ns (in 1 GHz mainframes: 11402, 11402A, 11403, 11403A, DSA601A, DSA602A)
• Input Impedance: Switchable 1 MΩ or 50 Ω; 75 Ω option available (11A34V variant for video applications)
• Deflection Factor: 1 mV to 10 V/division, 1% calibrated increments
• DC Offset: ±1 V range with 25 µV resolution at 1 mV/div; supports 2000-division effective screen height and ±0.4% absolute DC measurement accuracy
• Input Overload Protection: 5 VRMS in 50 Ω mode with manual reset – Key Features • Four independent differential display and trigger outputs driving 50 Ω per side mainframe inputs
• Auxiliary output per channel (200 Ω source impedance, reduced to 50 Ω via onboard shunt resistors)
• TEKPROBE® Level 1 and Level 2 probe compatibility with automatic probe-encoding detection
• BNC connector support for standard probes and cables
• Non-volatile memory (DS1220Y NVRAM) for settings, calibration constants, and serial number storage
• M377 IC output amplification stage – Compatibility & Integration The 11A34 integrates with any 11000-series oscilloscope mainframe accepting plug-in vertical amplifiers. Overall system bandwidth depends on selected mainframe specifications. TEKPROBE® probes (Level 1/2) provide automatic configuration and enhanced measurement capabilities.
