Mixed Signal Tektronix Oscilloscopes for Monitoring, Correlation and Debugging

The MSO4000 Tektronix oscilloscope series includes four models with bandwidths ranging from 350MHz to 1GHz, with two or four analog channels and 16 digital channels, providing up to 20 time-correlated channels. The MSO4032 and MSO4034 provide 350MHz bandwidth on two and four analog channels, respectively. The MSO4054 provides 500MHz bandwidth on four analog channels, and the MSO4104 provides 1GHz bandwidth on four analog channels.

The MSO4104 provides a 5GS/s sampling rate on all channels, while the other models provide a 2.5GS/s sampling rate on all channels. All models come standard with 10M of recording memory on all analog and digital channels.

The MSO4000 provides two methods for capturing digital waveform data. 1) The main digital acquisition mode captures 10M samples at a sampling rate of 500MS/s (2ns resolution). 2) The MSO4000 also provides MagniVu ultra-high resolution signal acquisition technology, which acquires 10,000 samples at a sampling rate of up to 16.5GS/s (60.6ps resolution). The Tektronix oscilloscope acquires waveform data in both the main mode and the MagniVu mode at each trigger, and users can view these waveforms at any time, whether running or stopped.

MSO4000 provides a breakthrough WaveInspector on all analog and digital channels, which can discover and effectively view, find and analyze waveform data. Through automatic waveform translation and scrolling display, user-defined marks and intelligent search and find functions. All MSO4000 models provide a 10.4-inch XGA color display, a thickness of only 13.7cm, and a weight of 2.5kg, which is very suitable for carrying.

The MSO4000 also combines industry-leading technical specifications, user-familiar operation, innovative debugging capabilities, and comprehensive functional support to monitor, trigger, and decode parallel buses and serial buses commonly used in embedded designs, such as I2C, SPI, CAN, and RS-232.

Classification by structure and performance

① Ordinary Tektronix oscilloscope. It has a simple circuit structure, narrow frequency band, poor scanning linearity, and is only used to observe waveforms.

② Use Tektronix oscilloscopes. They have a wide frequency band and good scanning linearity, and can perform quantitative tests on DC, low frequency, high frequency, ultra-high frequency and pulse signals. With the help of amplitude calibrators and time calibrators, the measurement accuracy can reach ±5%.

③ Multi-line Tektronix oscilloscope. It uses multi-beam oscilloscope tubes and can display the waveforms of more than two signals of the same frequency on the screen at the same time, without time difference and with accurate timing relationship.

④ Multi-trace Tektronix oscilloscope. It has the structure of electronic switch and gate control circuit, and can display the waveforms of more than two signals of the same frequency on the fluorescent screen of a single beam oscilloscope tube at the same time. However, there is a time difference, and the timing relationship is not accurate.

⑤ Sampling Tektronix oscilloscope. It uses sampling technology to convert high-frequency signals into analog low-frequency signals for display, and the effective frequency band can reach GHz level.

⑥ Memory Tektronix oscilloscope. Using storage oscilloscope or digital storage technology, single electrical signal transient process, non-periodic phenomenon and ultra-low frequency signal are retained on the oscilloscope screen or stored in the circuit for a long time for repeated testing.

⑦ Digital Tektronix oscilloscope. It has a microprocessor inside and a digital display outside. Some products can display both waveforms and characters on the oscilloscope screen. The measured signal is sent to the data storage device through the analog-to-digital converter (A/D converter). Through keyboard operation, the captured waveform parameter data can be added, subtracted, multiplied, divided, averaged, squared, and root-mean-squared, and the answer number can be displayed.
