Arithmetic and Analysis Functions
• Arithmetic Functions
User functions up to six USER FUNCTIONs can be defined using
arithmetic expressions. Measured data and analyzed
variables from graphics analysis (marker, cursor and line
data) can be used in the computation. The results can be
displayed on the screen.
Arithmetic operators
+,-,*, /, ^, LGT (logarithm, base 10), LOG (logarithm, base
e), EXP (Napierian constant), DELTA, DIFF (differential),
INTEG (integration), MAVG (moving average), SQRT,
ABS (absolute), MAX, MIN, AVG (averaging),
COND (conditional evaluation).
Physical constants Keyboard constants are stored in memory as follows.
• q : Electron Charge, 1.602177 E-19 C
• k : Boltzmann's Constant, 1.380658 E-23
• e : Dielectric Constant of vacuum, 8.854188 E-12
Engineering units The following unit symbols are also available on the
keyboard. m (10
-3
), μ (10
-6
), u (10
-6
), n (10
-9
), p (10
-12
),
f(10
-15
), k (10
3
), M (10
6
), G (10

)
• Analysis Capabilities
Overlay graph comparison
a graphic plot can be stored and later recalled as an overlay
plane. Four overlay planes can be stored. One plane can be
overlaid onto the current data.
Marker marker to min/max, interpolation, direct marker, and marker
skip
Cursor long and short, direct cursor
Line two lines, normal mode, grad mode, tangent mode, and
regression mode
Scaling auto scale and zoom
