Re: Spectrum analyzer Tektronix 7L13 on mainframe Tektronix 7603
Greetings Attilio - I did some research on the 502, and the xtal that tek used.toggle quoted messageShow quoted text
It is a SC cut 3d overtone series resonant crystal in a TO-5 transistor package.
Bliley Crystal in the US still might offer this cut.
The parts I have are AT cut 3 OT 7pF shunt resonant. My experience with them
is that they have a sharp resonance range. In the 502, the crystal Fc is stretched in
a VCXO circuit to effect the tracking of the SA. An AT cut crystal will move a bit
in frequency then just quit oscillating. It will also not fit in the available space. -J-

do you have any news for me in relation to 52.5 MHz crystal?
I am in Italy, if you give me your bank details and the amount I have to pay for the crystal and the shipping costs, I will make you an international bank transfer
Alternatively I can pay with PayPal..
