Tektronix 7904A + 7A13 + 7A18 + 7B85 + 7B92A Modules – 4 Channel 500 MHz 500 ps Modular Analog Oscilloscope Technical Specifications

Modules Included with the Product

• Tektronix 7A13 Differential Comparator: Vertical amplifier module providing sensitive signal comparisons, differential measurements, and high DC offset stability.

• Tektronix 7A18 Dual Trace Amplifier: Vertical amplifier module with two independent analog input channels and step voltage scaling.

• Tektronix 7B85 Delay Time Base: Horizontal time base module with Delta Time (Δ TIME) capability for double time base delayed scan measurements.

• Tektronix 7B92A Dual Time Base: Advanced triggering modes and optimized for high-frequency signal tracking.

• Bandwidth: 500 MHz hardware baseband support at the chassis level.

• Number of Available Channels: 3 active horizontal analog input channels via the amplifier modules installed in the system.

• Horizontal Time Base Resolution: 500 picoseconds per division (500 ps/div) horizontal time base resolution at the highest calibrated scan rate.

• Vertical Modes: Multiple signal combinations of LEFT, ALT, ADD, CHOP, and RIGHT for flexible monitoring between disconnected vertical modules.

• Horizontal Modes: A, ALT, CHOP, and B independent scan controls for advanced dual-time base delayed signal analysis.

• Screen and Reading Features: Wide-screen high-resolution analog CRT screen structure and built-in screen readout technology that displays the module scale values in real time.

• Signal and calibrator Outputs: The sensitive amplitude reference calibrator output on the front panel, along with the +SAWTOOTH, +GATE, and SIG OUT external connection terminals.

• Screen Control: The front panel features independent Focus, Astigmatism, Trace Rotation, and Beamfinder functions for net signal tracking.
