从Agilent 16720A没有生成数据和时钟

您好我使用数据POD 3.3 V和时钟POD 3.3 V通过Agilent Logic Analyzer的Pattern生成器生成60 MHz的数据流和内部时钟。
然后将POD连接到FPGA，逻辑分析仪的输出PODS显示数据是否生成。
问题是没有数据在FPGA上生成。
当我通过示波器检查FPGA输入引脚上的信号时，会产生模式，但pk-to-pk电压为mV。
当我将POD更改为2.5 V和1.8 V时，信号电压电平会恶化。
你能帮我确定一下是什么问题吗？
我是否必须在模式生成上设置任何阈值？
如何以及在哪里这样做？
我错过了什么？

  Hi  
I have used data POD 3.3 V and clock POD 3.3 V for the generation of data stream and internal clock of 60 MHz through Pattern generator of Agilent Logic Analyzer. The PODs are then connected to FPGA and output PODS of Logic Analyzer show whether the data is generated or not. The problem no data is being generated on FPGA. When I checked the signals on Input pins of FPGA through oscilloscope, the pattern is generated but the pk-to-pk voltage is in mV. As I change the PODs to 2.5 V and 1.8 V, the signal voltage level deteriorates. Can you help me determine what is the problem? Do I have to set any threshold on Pattern generation? How and where to do that? What am I missing?
