I bought my HP 606B locally thru Facebook Marketplace for $35. It required some repair. But to obtain the accuracy with it or any other marker source, you will require a frequency counter.
Decent sweep generators are easy to find cheaply. Coupling the equipment should be straight forward if you follow the procedure outlined.
You will be able to get the responses depicted only if you have the proper equipment and you can trust your frequency source.
And I only ended up with the HP606B because it was cheap and available. I have have three different HP frequency counters which I obtained over time because they happened to be cheap and were readily available. I believe we live in a fortunate time where so much 1960s and 1970s test equipment which we once could only dream of are now available for next to nothing.
What have you to measure the frequency source accurately?
