Re: B&K Precision 1524 Oscope

Thanks for the reply's.

I have verified that the sweep variable knob was in CAL position. (its printed on front bezel - Cal pos with a clockwise arror)

I am going to get another probe and test with that to verify that its not my old probe. (its a 60mhz probe)

I will continue to look for the manual to see if I can adjust it. I don't have a calibrated freq gen but I think if I use another calibrated scope (from work) and make the 2 match in freq readings, I will be ok.

Recently picked up B&K Precision 1524 Oscope on ebay.
when using the 1Khz test sq wave I noticed it appears as a 500hz wave. V is ok.
I then measured the 120VAC wall outlet. It too has an incorrect freq

I can use the variable sweep knob to correct the freq of the 1Khz test waveform and when I then measure the 120VAC 60Hz wall outlet the freq is correct. Is this just an issue of the scope or is that the reason the knob is there to begin with?

(at 1ms/div the 1 Khz test wave takes up 2 squares)

If its the scope, does anyone know how...
