2019年12月31日 · let's say I have a processor runs at 100MHZ frequency how can I compute from this it's clock time for each cycle? I know that Frequency = 1 / Clock Time but I am having trouble to fully understand how to manually convert it for example, to a nanosecond, given the frequency. Thanks!

2015年12月22日 · In the end, you will have filtered the signals over 100MHz anyway, so no big diference with using a 100MHz probe. In the other hand, if you use a probe with lower bandwidth, then it will determine the bandwidth of your input filter, and you will have less bandwidth in …

2024年12月12日 · By setting the output frequency in proportion (here is 5X), we can get any output up to 100Mhz through DDS Arb mode. Here is a 50Mhz sine wave 4, FFT test above 25Mhz 50Mhz with 100M span 100Mhz with 500M span 100Mhz with 1M span at 50Mhz, the signal drops to -0.14dBm at 100Mhz, it drops to about -1.1dBm This …

2018年3月2日 · Having more than 100MHz BW also requires more advanced probing techniques, and often 50 Ohm terminated inputs. Your vanilla 10x scope probe won't make any use of more than 100MHz BW - you'll just see more ringing. So 100MHz, or even as low as 50MHz is enough for the most tasks in debugging analog and uC circuitry.
