I have an SM435B model and I am having a really hard time trying to set a 2nd Marker to the next highest peak. First, I select Peak Search so it goes to the highest tone then I select Peak Right and it doesn’t seem to pick up the signal on the right. I tried dragging the marker closer to the undesired signal and selecting Peak Right again but it does not go to the signal’s peak.
I’ve tried playing with Pk Threshold and Pk Excurs but they have no effect.
Any ideas or suggestions?Hi Zitro,
If you wanted to provide a picture of the screen I might be able to provide you the best settings to accomplish this. I can try to describe what I think would be the best approach based on your description.
The Pk threshold should be lower than any of the peaks you anticipate measuring. If it is higher than your second peak, then it won’t work. If your second peaks is very close to the noise floor (doesn’t rise out of the noise floor much), you could reduce the Pk Excursion from 6 to something smaller.
With that setup, I would then press “Peak search” and then “Next Peak” to find the second highest peak.
Another alternative is to use the peak table to show all peaks simultaneously. You can find the peak table in the control panel along the bottom of the screen while in sweep mode.
If none of the suggestions above work, please provide a picture of your spectrum.
Do you have a picture of the spectrum so I can provide some specific suggestions?
Also, if the marker does not stay at the peak, then it sounds like the input frequency is drifting, is that a correct assumption?
If you set peak threshold to a very low value, it is essentially “turned off”.
Did you try the peak table?
