Dear all, In this series of videos, I now posted an episode on the Power Analysis functions of the Siglent SDS2000X plus. While also looking at power measurements using the R&S RTB2000 and Keysight DSOX1000, the primary comparison is with a dedicated power meter, the GW INSTEK GPM-8310. Enjoy! |

@RBBVNL9 Hello, just a note, you cannot do this kind of math (you used on efficiency calculations) on either Keysight or RTB2000. Keysight has only simple math and RTB2000 has different math architecture without formula editor. |

Hi 2N3055, --- Code: ---just a note, you cannot do this kind of math (you used on efficiency calculations) on either Keysight or RTB2000. Keysight has only simple math and RTB2000 has different math architecture without formula editor. --- End code --- It’s true that the Siglent has a formulae editor, which the RTB does not. Yet, the RTB has five math channels (compared to 2 in the Siglent). So, what you typically do, is to break down tasks. The formula you refer to can be broken down into several parts (see the attached screenshot), which have the end result. I understand some will really prefer scopes with a math formula editor (I myself particularly like the one in the PicoScope). And there certainly are formulas that cannot be broken down into parts the RTB can handle. On the other hand, having five math channels, like the RTB, can be valuable in other situations. Moreover, if you use it to break down a formula, you can also monitor each element separately in a measurement function, which can be useful for tracking issues. The Keysight DSOX1000 is much more basic when it comes to math: one channel only, and no formulae editor. |

For simple stuff you can get 5 Math traces. For complicated stuff only one or you cannot accomplish it. On SDS2000X+you have 2 Math channels but you can perform complex math on both. So sometimes RTB can be better if you need more simple math. True is that today, price range comparison of RTB2000 would be with SDS2000XHD, that has 4 complex channels.... Yes Picoscope is another level.. I have 3... :o |

I have now updated the series of comparison videos with an episode on math channels. Enjoy! |
