E8267D PSG怎么生成两个sin信号

HelloCan E8257D PSG产生两个sin信号,其中可以编程这些信号的相位差。例如:信号1表示为:S1 = sin(100 * w),信号2可表示为S2 = sin(100 * w)
+ delt)其中delt是可编程的。
如果一台设备无法完成这项工作,我可以使用两台E8257D PSG设备生成这两个信号。谢谢。

  Hello
Can E8257D PSG generate two sin signals where the difference of phase of these signals can be programmed.
For example:
signal 1 is expressed as : S1 = sin(100*w)
and signal 2 can be expressed as S2 = sin(100*w+delt) where delt is programmable.
If one device can't finish this job, can I generate these two signals with two   E8257D PSG devices.
Thanks.

Hi-Yes,可以使用Multitone功能在E8267D上生成两个正弦信号。
Multitone功能允许您创建从100Hz到80MHz间隔的2到64个音调,并独立编程每个音调的相位和幅度。
请注意,Multitone功能仅存在于E8267D矢量PSG中,而不存在于E8257D模拟PSG中。为了使用E8257D模拟PSG实现此功能,您需要两个信号源(每个音调一个)和一个合路器。
然后,您就可以独立编程每个源的阶段.Regards -

  Hi -

Yes, two sine signals can be generated on the E8267D using the Multitone feature. The Multitone function allows you to create from 2 to 64 tones spaced from 100Hz to 80MHz and to program the
phase and amplitude of each one independently. Note the Multitone feature is only found in the E8267D vector PSG and not in the E8257D analog PSG.
In order to accomplish this using the E8257D analog PSG you would need two sources (one for each tone) and a combiner. You would then be able to program the phase of each source independently.
