HP 1B, 2B, 71450B Using Math and Move Commands

Using Math and Move Commands

This section covers math and move commands which modify data and store the results in memory. In addition, four rules are provided for using math with trace arrays and elements.

Each math and move command requires both source and destination arguments. The value of the source is used to obtain the data stored in the destination. Only variables or traces can be a destination. Sources can be variables, traces, real numbers, or any command listed in the following table. (The commands in this table can only be used with commands whose syntax diagram shows predefined function as a source. Syntax diagrams for each command are illustrated in Chapter 7.)

Commands That Can Be a Source

Command					De￿nition
AMPU	Amplitude-unit			conversion
FUNCDEF	Create user-de￿ned function
MEAN	Mean value of data points
MEASU	Measurement-unit				conversion
MEM	Available	internal memory
MKBW	Marker	bandwidth
MODADD	Return slave module's HP-MSIB address
MODID	Identify	module		or	instrument HP-MSIB address
PEAKS	Trace peaks		found
POSU	Position-unit		conversion
PWRBW	Power bandwidth
RMS	Root mean square
STB	Status b yte
STDEV	Standard deviation				of trace values
SUM	Sum
SUMSQR	Sum of squares
VARIANCE	Variance
WLUNITS	Wavelength-unit conversion

Below, the MOV command transfers a value from the source (prede￿ned variable) to the destination (user-de￿ned variable).
