No way to find which frequency is generated since SDK?

Post by JavB » Thu Oct 23, 2014 10:19 am

Hello,

When you use the signal generator in a range of frequencies, b.e: since 1000 hz to 20000 hz, is there any way (function) to know what frecuency is applied at a determined time ?

we haven´t see any function at the programmer´s guide.

thanks in advance

I assume you're talking about a sweep scenario and you want to query the scope to ask it what is the current frequency while it's sweeping. I don't see any API to do that.

Could you spare an input channel to measure the frequency?

Otherwise, depending on your application , you could probably manually implement your own sweeping - e.g composing a larger sweep from multiple smaller ones. With some timers on the PC side you could estimate when each smaller sweep is done and take a measurement.

Hi,

Unfortunately there is not way using the API functions we provide to find the current frequency of the signal.

Like hexamer said could you spare a channel to measure the frequency?

And most of our device will also allow you to change the frequency during capture,
so you could alter the frequency yourself.

If you have any questions regarding this please post here or email at support@picotech.com
