high frequency analyzer
解釋
高諧波分析器-
I designed both hardware and software to develop the multi - channel analyzer, of which the key is the pc / 104 embedded computer. in a word, it has five traits as follows : ( 1 ) the key of apparatus is the pc / 104 embedded computer ; ( 2 ) on the hardware, we introduce the high - speed a / d conversion component - max191 to improve the mca ' s conversion speed and meet the demand on the spot ; ( 3 ) adopting high frequency module of electrical source to reduce its volume. ( 4 ) the mca consumes low power no more than 3. 9 watt
以國土資源部項目為依託，以pc 104嵌入式微機為平臺，完成了小型、低功耗能譜採集系統，特點是： （ 1 ）以pc 104嵌入式微機為平臺，實現了採集系統微機化； （ 2 ）採用高速低功耗a d器件maxl91 ，與現有的mca相比，提高了轉換速度，降低了mca的功耗； （ 3 ）採用高頻模塊電源，減小了採集系統的體積； （ 4 ）整機功耗低，小於3 . 9w ； （ 5 ）儀器重量輕。 -
The 2503ah power analysis instruments come with preprogrammed configurations for electronic ballast testing, several 3 phase and motor test configurations. you may configure the 2503ah - 3ch as 3 independent power analyzers, or as the most advanced 3 phase analyzer. for electronic ballast testing, one channel may be set up to measure line input dais, while the other two channels measure the high frequency signals
Xitron儀器已為電子鎮流器測試制訂速度與準確度的新標準，高速fft處理器能將鎮流器測試時間縮減可高達75 % ，測試參數包括效率，功率因素，失真及個別的諧波內容， 2503ah系列可完全支援iec - 555符合測試，亦為先進的測試實驗室，測試系統製造商及全球三大照明產品製造商所廣泛採用 -
