Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Figure 4. A snapshot, in time, of two complex numbers whose exponents, and thus their phase angles, change with time. The notion of negative frequency is often troubling to engineers who've spent so ...

Electrical engineering students rarely leave college with knowledge depth in both digital electronics and RF/microwave theory. The new engineer with digital design skills likely chose that path from a ...

Every electronic circuit has some noise and it can affect both analog and digital circuits. Some noise comes from outside interference while some comes from random factors such as thermal effects.

Over on his YouTube channel our hacker [CircuitValley] repairs an old TDS8000 scope. The TDS8000 was manufactured by Tektronix circa 2001 and was also marketed as the CSA8000 Communications Signal ...
