First 56-GBd optical probes for real-time scopes help troubleshoot 400G PAM4 components
The industry’s first 56 GBd 400G PAM4 optical probe is designed for use with Tektronix DPO70000SX Series real-time oscilloscopes. The new 59 GHz DPO7OE2 single-mode optical probe delivers the performance and advanced debug capabilities designers need to troubleshoot 400G PAM4 components and reduce time to market. Compared to 100G with NRZ modulation, 400G with PAM4 […]
Scope optical modules boast high sensitivity, low noise
Two new optical modules for the Tektronix DSA8300 sampling oscilloscope offer the industry’s highest sensitivity and lowest noise, helpful for analyzing 400G designs moving into production. Tektronix also announced enhanced support for the latest 400G PAM4 TDECQ measurements with a software package optimized for 4 channel parallel processing for high throughput manufacturing test. “As 400G […]
Testing and debugging the I2C digital data bus
“Bus” is an old term derived from conductive elements that are part of an electrical distribution system, generally referring to short specialized conductors separate from the overhead or underground cable. Typically, the old-style buses consist of bare copper bars, often having a rectangular cross-section, firmly mounted in an enclosure and capable of carrying current at […]
Measuring clock and oscillator frequency
A clock may refer to an oscillator that has been designed to provide a timing signal to facilitate operation of one or more synchronous processors. In contrast, asynchronous operation does not require a clock because each step initiates upon completion of a prior step. It is potentially faster than synchronous operation because there is not […]
Basics of measurement resolution
In electronic instrumentation, resolution is a measure of the distance in amplitude at which we can distinguish between two points on a waveform. This is not the same as accuracy, which is a measure of how closely a waveform as displayed or measured agrees with the signal at the instrument’s input. One of the principal […]
VIDEO: Domains in the Tektronix MDO3000 Oscilloscope
An overview of time and frequency domains and demonstration of the Spectrogram. Hi again and welcome to our 85th Test and Measurement Video. Today we’ll talk about domains in the Tektronix MDO3000 oscilloscope. By way of background, in mathematics a function is frequently graphed in Cartesian coordinates. Two axes intersect at right angles at the […]
VIDEO: Wave Inspector in the Tektronix MDO3000 Oscilloscope
An overview of Wave Inspector in the Tektronix MDO3000 Oscilloscope in time and frequency domains. Hi again and welcome to our 84th Test and Measurement Video. Today’s topic is an overview of the Wave Inspector function in the Tektronix MDO3000 Series Oscilloscope. This interesting aspect of the instrument permits the user to take a closer […]
VIDEO: Positioning and Scaling Waveforms in the Tektronix MDO3000 Oscilloscope
A demonstration of waveform positioning and scaling together with an overview of the Wave Inspector function. Greetings once more and welcome to our 83rd Test and Measurement Video. Today’s topic is Positioning and Scaling Waveforms. This is a rather simple process because it is done merely by turning a few knobs, but it does take […]
VIDEO: Sampling Modes in the Tektronix MDO3000 Oscilloscope
A demonstration of sample mode, peak detect mode, high-resolution mode, envelope mode and average mode. Hi and welcome again to our 82nd Test and Measurement Video. The topic before us is sampling modes in the Tektronix MDO3000 Digital Storage Oscilloscope. Virtually all oscilloscopes and spectrum analyzers manufactured today are digital rather than analog. The advantage […]
