Here's the 34401A pics. As I said looks brand new. The cal count is 75 though so it'd be interesting to know what it's been doing all these years. The freq. spec is up to 300 kHz but it works well far above that. No other issues noted.
(Yea the comma is off now
)
Wow, xrunner! That really does look fresh out of the box. Congrats!
As for the cal count, a complete adjustment increases the count by about 35 (if they get everything right in one go). So, yours may have had one full adjustment (or a couple of partials) since its original setup at the factory.
That looks excellent. Congratulations!
My cal count is 35. It’s not unusual for them to have to run the cal cycle ten times before the monkey in charge gets it right each time.
Sounds like yours hasn't been touched since it was released into the wild, bd.
(Out of curiosity, checked my count and it's 48. Revision is 11-05-02.)
