To change and readjust the laser in my Harman HD7725 the service manual notes that I need a DC Voltmeter for power adjustment, an oscilloscope for EF Balance and a jitter meter.

What exactly measures the jitter meter?
It is needed for adjusting the focus offset and the jitter inclination confirmation.

Can I measure this in a different way?

Oh and where to get a EIAJ CD-1 Test Disc? Whats on it?
