Modeling a Max Hold Function
The following example shows you how to emulate a max hold function.
// Reset the analyzer
*RST
:DISPlay:WINDow1:TITLe:DATA 'Max Hold Function Emulation'
// Create a trace with the last extremum as memory trace.
:TRACe:COPY 'LastExtr', 'Trc1'
// Display this last extremum trace.
// Because it's a memory trace it must be displayed in the same diagram as the mother trace.
:DISPlay:WINDow1:TRACe2:FEED 'LastExtr'
:CALCulate1:MATH:SDEFine 'Max (Data, Mem)'
:CALCulate1:MATH:STATe ON
// Single sweep mode
:INITIATE:CONTINUOUS OFF
// Do a single sweep and update trace with the current extremum.
// This is the last extremum for the next sweep
