content: I have an HP5335A universal counter.This "thing" usually displays 10 characters max, but I understand there IS a way to display 11 or 12 characters. Manual infers this by saying if displaying more, separator spaces will be omitted. Manual doesn't mention how to do this though - except stating in manual mode, I can start and stop by pressing that button.Can ANYONE tell me how stupid I am by showing me how easy it is to do this??

content: Dr.Frank had a small modif to display 10 digits on the display. seehttps://www.eevblog.com/forum/testgear/hp-5335a-timer-counter-anything-i-should-know/msg451214/#msg451214Also GPIB should give you 11 digits resolution.

content: Yes, I know that thread. I've read from post 1 to the end.I take it either go HPIB or modify and there are no buttons or setups to take full advantage of 12 digits? Hum.... Seem to be an odd design.

content: Quote from: tkamiya on January 23, 2019, 10:19:44 pmLet me ask the guy I bought mine from if he knows of any such "hidden" functionality. Some of the functions such as Freq B are of course hidden in a menu that you access by Scale -> Smooth then key in an integer.

content: Special functions are described in the manual page 3-4. They are not necessarily easy to get to but they are not hidden.17 = FREQ B18 = PULSE B19 = TIME B->A20 = TOTALIZE A-BSee 5335a manualhttps://literature.cdn.keysight.com/litweb/pdf/05335-90005.pdf?id=722720

content: Quote from: Kosmic on January 24, 2019, 03:33:16 amI'd say they are in fact hidden because it is not obvious how to access them without the manual.

content: I use a function generator to externally gate the counter for 15 second periods to get 11 digits resolution.
