各位先進好
小弟最近在使用ADE7880諧波功能 在三相四線式量測各相ITHD與VTHD都沒問題
在測試三相三線式(Delta接)時 所獲得的ITHD也可以正確計算出來
但在VTHD的部分無法從數據上得到一個正確的數值
後來嘗試從XVRMS跟FVRMS來自行計算 但也無法獲得正確的結果
想請問各位先進是否有其他方式可以得到三相三線式的VTHD數值呢 謝謝~~

Hi,
In a recent work,we found several pieces of AD9516 that did not have an clock output . At the same time, their BAPASS pin voltage is 1.8v, while the working AD9516 BAPASS pin voltage is 2.5V.
Could you give me some advice, please?
在3相4線式時抓取KW跟PF都OK.
可是在3相3線B接在N時,要抓B相KW跟PF都是無值.
請教要如何求出來,謝謝
Hi!
I am an absolute beginner in usage of video DACs so forgive me for asking a question that might be very obvious to most people here.
I am trying to use an adv7125 as a means to process some 3 bit digital rgb signals from an old computer.
According…
Does Analog Devices has a part with multiple video decoders ? I need 3 video decoders for 3 PAL cameras
Hi,
In my company, we are developing a video security system using 3 analog cameras, so we decided to use ADV7180 (40 pin version).
The three analog video inputs are multiplexed, so we wonder if we can get the video from the 3 cameras simultaneously. O…
Please provide the SDI and SDO data for the entire command step sequence and the schematic.
Also, please provide a scope shot of the write and read frames.
It is certainly not possible for the register readback to be different from what you have written…
When ACE is used to set the register control word of AD9154,Under Link0, there are two pages, DAC0/1 and DAC2/3.When setting the data-format register, either directly or register debugI can only change the value of DCA0/1, which causes my DAC2/3 channel…
I would like to use a Manual Push Button Reset with the LTC2901-3. Please see the schematic below...
