HI,
I encountered a 3458A with stored as a user defined key. I have been looking for documentation and found none. Where can I find out what this does and how to use it?

Is there a way to do RMATH UPPER -RMATH LOWER in one user defined key?

Thanks,
John

It's documented in the user manual, command reference.
Use the DEFKEY? command to read the stored functions.
Normally, that command string should consist of a concatenation of the documented functions in the mentioned command reference.

Perhaps you may post the string here, if it's unclear.
...
Theoretically, it should be possible to call both functions in one instance, but you have to check, what is really delivered to the output buffer.
If there is no error, I assume, that this call may deliver the lower value only. Just test "RMATH UPPER; RMATH LOWER"

Search for the Fluke 3458A - HFL manual.
They have programmed some useful statistical functions to the function keys, lower and upper are sitting on two different keys.

  I have a meter with RIG; RMATH MEAN stored. The question is what dose RIG do? It looks like the sours for the stat function then the mean values is read.

    Hello,
    
    This function key can only have been programmed over GPIB, but not over the keyboard.
    
    In the firmware, there is no command as RIG, also no hidden one.
    
    I assume, RIG was originally TRIG, but then a typo occurred, so you will get an error, if you call that function.

      Hi.
      
      I want to set up some user-defined key functions for my 3458A such as Null and dB, similar to the functions on the 34401A and others. I previously read where this can be done only over GPIB control - is that correct?
      
      Also, is there a part number or source for the 3458A keyboard overlay?
      
      Thanks for your help.
