我正在使用N4392A + 89600 VSA和OMA 4.1光扩展获得28 GBd到32 GBd的QPSK和16QAM光信号。
器件的采样率为63 GSa / s,我可以选择每个符号的采样数(2到20)。 但是,系统仅允许保存长度为4096个符号的迹线。 是否可以保存更长的痕迹? 我相信样本内存允许它(16000个样本),即63 GSa / s,28 GBd和2个样本/符号,一个应该能够保存多达7111个符号,而不仅仅是4096个。是否可以保存原始内存 ADC时间轨迹(无插值)为63 GS / s? 谢谢你,马丁 以上来自于谷歌翻译 以下为原文 I'm acquiring 28 GBd to 32 GBd QPSK and 16QAM optical signals using N4392A + 89600 VSA with OMA 4.1 optical extension. The sample rate of the device is 63 GSa/s and I can choose the number of samples per symbol (2 to 20). However, the system only allows saving traces of length of 4096 symbols. Is it possible to save longer traces? I believe the sample memory allows it (16000 samples), i.e., with 63 GSa/s, 28 GBd and 2 samples/symbol, one should be able to save up to 7111 symbols, not only 4096. Is it possible to save the raw ADC time trace (without interpolation) at 63 GS/s? Thank you, Martin |

在Keysight OMA中,您可以获得的样本数量与您在问题中提到的项目无关。
N4392A每通道最多可采集16000个样本。 一次屏幕更新中最多可分析4096个符号。 下一个屏幕更新将采用下一个(最多)4096个符号。 OMA根据您的设置自行决定需要多少样品。 如果进行录制,则可以在播放分析期间进行连续重叠。 在任何情况下,N4392A中的最大样本数量限制为16000。 记录数据时,您已经获得原始数据而无需信号处理。 仅包括仪器硬件的频率均衡,其方式与常规示波器测量相同。 要获得存储在录制中的最大数据,请转到“输入 - >录制”并选择“最大长度”。 然后在菜单栏中按红点后保存数据以开始录制。 关心奥利弗 以上来自于谷歌翻译 以下为原文 In the Keysight OMA the number of samples you can acquire is not dependent on the items you mention in your questions. The N4392A can acquire maximum of 16000 samples per channel. Up to 4096 symbols can be analyzed in one screen update. The next screen update takes the next (up to) 4096 symbols. OMA decides on its own depending on your setting how much samples are required. If you do a recording you can make a continuous overlap during the playback analysis. In any case the maximum number of samples is limited to 16000 in the N4392A. When recording data you already get raw data without signal processing. Only frequency equalization of the instrument hardware is Included in the same way as with a regular oscilloscope measurement. To get maximum number of data stored in recording go to "Input-> Recording" and select "max length". Then save data after pressing red dot in menu bar to start recording. Regards Oliver |
