Example: Setting up a histogram
The following example creates a 15-bin histogram of 3,000 counter
measurements. The lower and upper ranges are automatically determined from
the first 300 readings taken.
CONF:FREQ 50E3, (@1)
INIT
*TRG
Resetting the histogram
The data from which the current histogram is created is cleared by any of the
following:
– pressing the Reset Histogram softkey
– enabling/disabling or changing any part of the histogram
– a new measurement cycle - INITiate:IMMediate, READ?, MEASure
– sending a new SCPI command or changing a current SCPI parameter
