创建一个只有两个相同波形的序列偏移为-500mV

嗨，我正在使用带有BenchLink Waveform Builder Pro的33500B进行一些序列加载。
我创建了一个具有两个梯形脉冲的单通道波形。
一个从0变为2v并返回到0.另一个变为负0到-1v并返回到0v。
我将它发送到单位，它报告的偏移量为500mV，但它正如你所期望的那样播出，两个脉冲以0v为中心。
但是，现在，如果我创建一个只有两个相同波形的序列并将其播出，它会将偏移设置为-500mV，这就是它如何播放我想将这个发生器连接到一些高功率放大器和一个偏移量
高会炸毁负载有谁知道这些补偿发生了什么？
谢谢

  Hi,

I am using a 33500B with BenchLink Waveform Builder Pro to do some sequence loading. I have created a single channel waveform which has two trapezoid pulses. One goes from 0 to 2v and back to 0. The other goes negative 0 to -1v and back to 0v. I sent it to the unit and it reports an offset of 500mV but it plays out as you would expect, the two pulses centered around 0v. However, now if I create a sequence which is just two of the same waveform and play it out, it sets the offset to -500mV  and that's how it plays out

I want to hook this generator up to some high powered amplifiers and an offset that high will blow up the load

Does anyone know what is going on with these offsets?

Thanks
