Re: Replacing cable on P6075A probe
Greeting, Also, take note of what the manual says about shortening the cable and Connector Replacement" page 2 ( 6 of 11) of the P6075A version from the links given earlier in this thread;toggle quoted messageShow quoted text
It is also repeated (or vise versa) in the plain P6075 manual on page 5 at the same link.
"Substitution of non-standard parts is not advisable if the original performance is to be restored. Even shortening the cable by more than a few percent will have a noticeable effect on the transient response of the probe. The resistive center conductor has been specifically selected for critical dampening of reflections that would otherwise exist."
And then is the "Conector Replacement" next with step 1 as "Remove the snap- fit cover on the compensation box." They dont tell you how to do that though. Perhaps the plastic has stiffened somewhat suggesting you need a good pry from a screwdriver. Perhaps a blade edge of knife gently if a finger nail wont budge it. It can also be stuck and needs to be cracked loose. If you nick or dint then you gotta fix that somehow........or I do. Leave no marks is the goal.
Im sure we have all seen somones attempt at opening stuff up, TVs, phones, etc that looked like a jackhammer attacked it everywhere. Use a screwdriver for what it was intended, prying open paint cans!!!
On a side note, what is the difference in the plain P6075 and the A version? I see the specs for the plain versions input impedance is 10meg within 0.4% and 0.5% for the A.

Not quite right to compare 250 to 10Meg and declare 200 to be therefore ok. By that logic, zero ohms should be just fine, too. Yet, Tek went to the trouble to use resistance wire. Clearly there's a reason!
