你可以看如下数据手册的描述：
The AD603 can drive a load impedance as low as 100 Ω with low distortion. For a 500 Ω load in shunt with 5 pF, the total harmonic distortion for a ±1 V sinusoidal output at 10 MHz is typically −60 dBc. he peak speciied output is ±2.5 V minimum into a 500 Ω load.
也就是说如果负载太小的话，就会有问题，所以建议你看一下示波器的输入阻抗是多少，如果输入阻抗比较小的话，建议你可以在输出端串联一个大电阻试试。
