Pointing eggsactly in File anlyzer

Hello

Hello

Does any one know how to get  exact pointing or tuning into  a carrier in the data  analyzer? Many times the pointer the steps even equal dotn seem to point exactly in the carrier ie 17490000.000 or 17530.000

In the second example as in the mini shot it steps to 17259976.8 and requires too careful mouse pointing to step up into 17530034[.662] so losing the carrier

Attached are the photos adjustment buttons in total zoom plus the whole screenshot Step can vary by 12,13+ Hz ±v and never get on 17490 in this case V of Tibet

the step down mouse pointing





this this step-down pointing with next step on 530034.xxx losing the exact carrier





I think that a zoom operation can help pointing  to carrier

For any arbitrary carrier frequency there is no way to do what you want. You can approximate by zooming way in and clicking. It's a screen pixel thing.

For situations where you see real channel spacing, e.g. 3 kHz for regions using SSB and 5 kHz for regions using HF AM you can use tools options to have the carrier snap to the nearest 1 kHz or other step size.

You can also place the mouse over a number on the frequency display, hold the shift key, and roll the mouse wheel. Digits to the right will be zeroed.
