The Tektronix 11302 is a 500 MHz analog oscilloscope mainframe built around a micro-channel plate CRT for superior visibility of fast transients and adaptive intensity normalization. It accepts Tektronix 11000-series plug-in modules, supporting up to eight simultaneous traces and delivering 6 cm/ns visual writing speed for high-fidelity signal capture.
– Technical Specifications
• Bandwidth: 500 MHz
• CRT Type: Micro-channel plate (MCP) with adaptive intensity
• Visual Writing Speed: 6 cm/ns
• Maximum Displayed Traces: Eight
• Integrated Counter-Timer: 500 MHz universal counter with frequency, period, width, ratio, totalize, and time interval (A→B) measurement modes
• Counter Input Channels: 12 plug-in input channels plus external A and B inputs
• Trigger Sensitivity: 0.35 divisions (internal) or 20 mV (external) up to 50 MHz; 1 division/150 mV at maximum bandwidth
• Trigger Modes: DC, AC (>50 Hz), HF Reject (80 kHz), TV (line or field)
• Auto Calibration: Optical sensing system for automatic calibration from plug-in input connector to graticule, including CRT deflection sensitivity
• Power Supply: PWM topology with power MOSFETs operating at 100 kHz fixed frequency; includes line filters, fuses, and thermistors for surge limiting and line-noise suppression
– Key Features
• Counter view function displays signals within the counter to verify measurement accuracy
• 11302A variant extends external counter input bandwidth to 750 MHz and adds readout mode button
• 11302A includes enhanced accuracy mode for automatic self-calibration of gain and timing
• Programmable control via IEEE-488 (GPIB) and RS-232C interfaces
• Benchtop form factor with low profile suitable for rackmounting
– Typical Applications
Fast transient capture, frequency and timing measurements, multi-channel signal analysis, automated test systems via GPIB or RS-232C control.
– Compatibility & Integration
Accepts all Tektronix 11000-series plug-in modules for flexible channel and measurement configurations.
