TEKTRONIX 5B12N is a dual time base plug-in module for Tektronix 5000 series oscilloscopes,designed for complex signal analysis.The following is a comprehensive analysis of its core functions and technical features:
I.Core functions and technical parameters
Dual time base scanning capability
A time base:The scanning range covers 1μs/Div to 5 s/Div(supports×10 magnification to 100 ns/Div),suitable for conventional signal capture.
B time base:The scanning range is 200 ns/Div to 500 ms/Div,supporting high-speed signal analysis and delayed scanning.
External trigger and input
External trigger input:supports±5V level,maximum tolerance 350V(DC+peak AC),suitable for complex trigger scenarios.
External X input:calibration range 50 mV/Div to 5 V/Div(variable),supports DC≥1 MHz signals,suitable for dual-channel signal synchronization in XY mode.
Delay and jitter control
Delay time:can be set to 0.2–10.2 times of time/Div,with an accuracy of 1%(≤0.5 s/Div)or 2%(≤5 s/Div).
Jitter performance:at 10 times time/div setting,jitter≤1 part/20,000 cycles,ensuring high-precision measurement.
XY mode and independent control
Supports XY mode,which can drive the X and Y axes of two channel signals separately for phase,frequency response or nonlinear characteristics analysis.
Provides independent time base position control,allowing users to flexibly adjust the display range and offset of the two time bases.
II.Compatibility and installation requirements
Applicable oscilloscope:Designed for Tektronix 5100 series oscilloscopes,it needs to be installed in the horizontal(right)compartment to achieve the best retrace blanking effect.
Trigger source selection:supports LEFT,RIGHT or COMPOSITE trigger mode to meet different measurement needs.
3.Application scenarios
Electronics and communications:Analysis of high-speed digital signals,pulse width modulation(PWM)or radio frequency signals.
Medical equipment:Capture the timing and amplitude relationship of bioelectric signals(such as electrocardiogram).
Industrial control:Monitor the timing synchronization of systems such as motor drive and power conversion.
4.Technical advantages
Modular design:Plug and play,no additional calibration required(calibrated at the factory).
High reliability:Supports 350V withstand voltage protection,suitable for strong interference industrial environments.
