HP 8590 E & L Series Spectrum Analyzers and HP 8591C Cable TV ...

EXP Exponent
Example 1
This example converts the marker amplitude to power units.
10 OUTPUT 718;"IP;" Initializes the spectrum analyzer
20 OUTPUT 718;"SNGLS;" Activates the single-sweep mode.
30 OUTPUT 718;"VARDEF P-MW,O;" Initializes variable P..MW to 0.
40 OUTPUT 718;"TS;MKPK HI;" Fino!s highest peak of sweep.
50 OUTPUT 718;"EXP P-MW,MKA,lO;" Divides the marker amplitude by 10, raises the
value of the marker amplitude to the power of 10,
60 OUTPUT 718;"P,MW?;"
70 ENTER 718;Number
80 DISP Number;"mW"
90 END
Example 2
and stores the results in P-MN?
Returns the value of PM to computer
Assigns value to computer variable.
Displays result on the computer screen.
This example finds the natural exponential of anumber and uses the LOG command to return
the original source value of the EXP function.
10 OUTPUT 718;"VARDEF E,XP,O;" Dejlnes a variable called E-XI?
20 OUTPUT 718;"EXP E,XP,2,2.30259;" Fino!s the natural exponential of 2.
30 OUTPUT 718;"E,XP?;" Returns the natural exponent of 2.
40 ENTER 718;Value
50 PRINT Value
60 OUTPUT 718;"LOG E-XP,E,XP,2.30259;"
70 OUTPUT 718;"E_XP?;"
80 ENTER 718;Logvalue
90 PRINT Logvalue
100 OUTPUT 718;"VARDEF E-XPY,O;"
110 OUTPUT 718;"EXP E-XPY,-5,2.30259;"
120 OUTPUT 718;"E_XPY?;"
130 ENTER 718;Value2
140 PRINT Value2
150 OUTPUT 718;"LOG E,XPY,E-XPY,2.30259;"
160 OUTPUT 718;"E_XPY?;"
170 ENTER 718;Logval
180 PRINT Logval
