 StairUpDn
The StairUpDn waveform is as shown in the figure below. The instrument
determines the StairUpDn waveform according to the maximum (denoted
by MAX), minimum (denoted by MIN), total number of points (denoted by
P) and time interval currently set and creates P parameters. When P is an
odd number, the value increase from MIN to MAX at the step of
(MAX-MIN)/int(P/2)
[1]
and then reduces to MIN at the same step.
When P is an even number, the value increases from MIN to MAX at the
step of (MAX-MIN)/{int(P/2)-1} and then reduces to MIN at the step
of (MAX-MIN)/int(P/2). The timing time is determined by the time
interval currently set.

Note
[1]
: int(P/2) indicates rounding P/2 (discard the decimal part).
 Exp Rise
The Exp Rise waveform is as shown in the figure below. The instrument
determines the Exp Rise waveform according to the maximum (denoted by
MAX), minimum (denoted by MIN), total number of points (denoted by P),
time interval and rise index (denoted by RiseIndex) currently set. The
waveform function is (MAX-MIN)*(1-e
-i*RiseIndex/P
); wherein, i is
independent variable and creates P groups of parameters from 0 to (P-1).
The timing time is determined by the time interval currently set.
