We have most older HP/Agilent, Tektronix, Wavetek, and Drantez parts

available for sale. We have a 450-square-foot warehouse of part units for

Tektronix Oscilloscopes, Spectrum Analyzers, Counter/Timers, Generators,

Tektronix plug-ins, Sweep Oscillators, Tektronix TDS scopes, and more. If we

do not have it, we can try to get it. We will need the make, model, serial #, and

year of the main unit. Then I would need the part you are looking for and its

serial or model # .
