如何使用PSG模拟斜坡扫描进行IMD和增益测量

嗨，我想使用模拟PSG和斜坡扫描选项进行以下测量。
通过产生两个间隔1MHz的音调并进行模拟斜坡扫描，使用两个PSG扫描IMD测量值。
我将PSG的o / p连接到我的设备，并在sectrum分析仪上测量设备的输出。
频率为6GHz和14GHz如何同步两个PSG同时开始扫描并同时结束？
我还需要触发频谱分析仪进行测量。我发现在PSG上，不同单位的扫描时间并不完全相同.Rgds

  hi,

I would like to do the following measurement using the analog PSG with the ramp sweep option.

1. swept IMD measurements using two PSGs by generating two tones that are 1MHz apart and doing an analog ramp sweep. I connect the o/p of the PSG to my device and measure the output of the device on a sectrum analyzer. The frequencies are at 6GHz and 14GHz

How do I synchronise the two PSGs to start the sweep at the same time and end at the same time? I also need to trigger the spectrum analyzer for the measurement.

I find that on the PSG, the sweep times are not exactly the same for different units.
