测量上升时间失败

我使用函数y = FrontPanel_wave_1st_transition_rise_time（data，base，top，base_threshold_pct，top_threshold_pct）来通过瞬态模拟来测量信号的上升时间。
我想扫描输入频率并测量每个输出的上升时间。
使用扫描时，此功能似乎失败。
有解决方法吗？
我意识到，虽然渗透频率，我的数据输出是一个二维数组，如果我通过使用y = FrontPanel_wave_1st_transition_rise_time（data [0，::]，base，top，base_threshold_pct，top_threshold_pct）指定频率索引，那么函数给了我
一个值。
有没有办法将频率索引作为变量，以便我可以获得每个输出的上升时间？



     以下为原文

  I am using the function  
y = FrontPanel_wave_1st_transition_rise_time(data,base,top,base_threshold_pct,top_threshold_pct)
to measure the rise time of a signal by transient simulation. I would like to sweep the input frequency and measure the rise time for each output. This function appears to be failing while using sweep. Is there a workaround?
I realise that while seeping the frequency, my data output is a 2 dimensional array and if I specify the frequency index by using  
y = FrontPanel_wave_1st_transition_rise_time(data[0,::],base,top,base_threshold_pct,top_threshold_pct)

then the function gives me a value. Is there a way to make the frequency index as a variable so that i can get the rise time for each output?
