是否可以使用VSA 89601A测量Shaped-OQPSK的EVM

是否可以使用VSA软件89601A测量Shaped-OQPSK信号的EVM？
具体来说，我感兴趣的是测量MIL-STD Shaped-OQPSK信号和IRIG Shaped-OQPSK-TG信号的EVM。
我似乎可以测量标准OQPSK信号的EVM，但我不知道这是否可以扩展为Shaped-OQPSK信号。
生成Shaped-OQPSK信号需要实现频率脉冲整形滤波器，但VSA软件中的用户定义滤波器似乎不是频率脉冲整形滤波器。
相反，用户定义的过滤器似乎过滤了单独的I和Q脉冲序列的流。
我无法弄清楚如何将频率脉冲整形滤波器转换为I / Q脉冲滤波器，我想知道这种转换是否可行。

  Is it possible to measure the EVM of a Shaped-OQPSK signal using the VSA software, 89601A?  Specifically, I am interested in measuring the EVM of a MIL-STD Shaped-OQPSK signal and an IRIG Shaped-OQPSK-TG signal.

It appears that I can measure the EVM of a standard OQPSK signal, but I do not know if this can be extended to a Shaped-OQPSK signal.  Generation of a Shaped-OQPSK signal requires implementation of a frequency pulse shaping filter, but the User Defined Filter in the VSA software does not appear to be a frequency-pulse shaping filter.  Rather, the User Defined Filter appears to filter streams of separate I and Q impulse trains.  I have not been able to figure out how to translate a frequency-pulse shaping filter to an I/Q impulse filter and am wondering if such a translation is even possible.
