在cilent中使用agilent 34410A得到-420查询未终止错误

问答对人有帮助，内容完整，我也想知道答案 0 嗨我在visual studio 2010中用c ++编写了一个函数，它根据定义的采样间隔计算定义数量os样本的平均电流消耗。问题是我偶尔得到-420查询未终止错误并且通信挂起。需要重新连接USB电缆才能恢复通信。首次打开设备后尤其会出现问题。我认为这可能是一个计时错误，所以我添加一些* WAI和* OPC？命令但没有效果。我在下面添加我的函数（并附加cpp文件）。任何帮助将不胜感激。 float MeasureAverageCurrentDC_mA（int sample_number，float sample_interval）{float result; if（sample_interval 600）sample_interval = 600; if（sample_number 50000）sample_number = 50000; char samp_num [10]; char samp_int [10]; char table [90]; char var1 [45] =“CONF：CURR：DC 0.1，DEF;：SAMP：COUN”; char var2 [45] =“：SAMP：SOUR tiM;：SAMP：TIM”; _itoa（sample_number，samp_num，10）; for（int i = 0; i 47＆amp;＆amp; tab [count] {licznik_kropka = licznik_kropka + 1; myvector [j] = tab [count] - '0'; j ++;} else {licznik_znakow = licznik_znakow + 1;}} if（czyE == 1）{for（int i = j + 2 + licznik_znakow; i {EE = EE +（tab [count] - '0'）;}} arraysize = j - 1; for（int i = 0; i {lolek = lolek +（myvector ）（pow（10.0，（arraysize-i）））;} lolek = lolek + myvector [arraysize]; if（czy_kropka == 1）result =（double）lolek / pow（10.0，licznik_kropka）;否则result =（double）lolek; if（czyE == 1）result = result / pow（10.0，EE）; delete [] myvector; res_table [count] = result;} for（int count = 0; count {sum = sum + res_table [count];} delete [] res_table; for（int i（0）; i delete [] tab ; delete [ ] tab; tab = NULL; return sum / result_counter;}编辑者：white-star于2015年11月5日上午1:52 以上来自于谷歌翻译以下为原文 Hi I wrote a function in visual studio 2010 in c++, which calculates the average current consumption from defined number os samples with defined sample interval. Problem is that i sporadically get -420 query unterminated error and communication hangs. Need to reconnect u** cable to resume communication. Problem especially occurs after first switch on of device. I thought it can be a timing error, so I add some WAI and OPC? commands but with no effect. I add my functions below (and attach cpp file).

答案对人有帮助，有参考价值 0 对于任何有类似问题的人。打开后问题在于适当的供电设备。打开后，设备并不总是自动检测到。有效的解决方案是关闭设备管理器中的u*省电选项，如下所述：http：//helpdeskgeek.com/windows-xp-tips/prevent-windows-from-powering-off-u-device/ It 安装最新的Keysight IO库也很不错。我认为这个话题可以关闭。以上来自于谷歌翻译以下为原文 For anyone who has similar issue. Problem lies in proper powering device after it is switched on. The device is not always auto-detected after it is switched on. The solution that worked is to switch off u power saving option in device manager in windows like described here: http://helpdeskgeek.com/windows-xp-tips/prevent-windows-from-powering-off-u*-device/ It is also good to have newest Keysight IO Libraries installed. I think the topic can be closed.
