%_resolution: Specifies resolution as a a 
percentage of the max._input parameter. (Refer 
to the FREQ and PER commands for tables 
showing how %_resolution affects frequency and 
period measurements: %_resolution is ignored 
when the function parameter is DSAC, DSDC, 
SSAC, or SSDC.)
Power-on %_resolution = none.
Default %_resolution:
FREQ or PER =.00001 (gate time=1s, 7 digits 
resolution).
SETACV SYNC = 0.01%
SETACV RNDM = 0.4%
For all other measurement functions, the default 
resolution is determined by the present 
integration time.
ID?
Identity Query. Causes the multimeter to send 
the string “Keysight 3458A”.
INBUF [control]
Input Buffer. Enables or disables the multimeter's 
input buffer. When enabled, the input buffer 
temporarily stores the commands it receives over 
the GPIB bus. This releases the bus immediately 
after a command is received, allowing the 
controller to perform other tasks while the 
multimeter executes the stored command.
control = OFF (0), ON (1)
Power-on control = OFF.
