I working on calibrating a oscilloscop.. I need a calibrated 60 Mhz and can this be made with basic parts and skills ???
Could you use a gps reference ???

Hello,
I think you mean 60 MHz and not 60 millihertz.
What accuracy would you expect from the generator?
Perhaps this 60 MHz TCXO will do the job:

Sorry I meant 60 Mhz and I am trying to output a sine or square wave to check the calibration of my Tek 2215.. The scopes max is 60 Mhz and it doesn't have to be 60Mhz but hopefully pretty close..
Hello,
According to this page:

The 60 MHz is the -3dB point of the vertical amplifier.

You need many frequencies to calibrate a scope. A time mark generator is usually used.
I have a DDS and signal generator and plus I picked up a Heathkit IG-4504 scope calibrator..
A time mark generator makes it easier to calibrate the timebase; it's listed as required equipment in the 2215A service manual.
What kind of project do you plan to work on that will require such a precisely calibrated scope?
I should probably explain myself a little clearer.. This scope turned on when I got it and never showed a signal when terminated cause the input resistors where shot.. After alot of help form the yahoo Tektronics group I figured a couple more issues and possible upgrades to the trigger system.. I just trying to make sure the scope is use able and somewhat calibrated ..
Do you want to calibrate the time base, or the amplitude at that frequency? Note that the bandwidth is usually up to the -3dB point.
You are better off verifying the bandwidth by using a squarewave. This will also show if there is overshoot or ringing in the vertical amp.
The relationship of bandwidth to risetime is 0.35/risetime. For example, a 10 MHz scope has a 35 ns risetime. The risetime of the squarewave must be much less than the risetime of the scope for this to be accurate.
