Adjusting the Ref clock

Is there a way to adjust the 10 MHz Reference oscillator in the TG44 and SA44? I don’t see any mechanical adjustment. Is there a software adjustment method?
While I can attach a very good reference oscillator when I’m on the bench, I don’t have that capability in the field. My units run about 20 hz high giving me a 2KHz error when I am looking at signals in the high 900 MHz range in the field. I realize the oscillator is not a high accuracy type. But if it could be adjusted closer for most room temp. readings at least the errors would be less.
Thanks

Hi Steve,

As of today, we have released a new version of Spike which will allow you to adjust the reference oscillator in your SA44, unfortunately it will not work with your TG.

Grab the new version of Spike at http://www.signalhound.com/Spike and check out the “Timebase Adjustment” under the utilities menu. You will input a CW into the RF input of the SA44, specify its power level and frequency and you can make one click adjustments. This should get your SA calibrated. It is a software calibration and can be reversed anytime by clearing it through the same utility.

Hope this helps, let me know if you have further questions.

Regards,
A.J.

Thanks for that. I downloaded the new SPIKE. It works very good. I now have much better freq accuracy. And I like the new analysis tools.
Good job.
