Rise/Fall Time
# Input range (V) — the range of the input signal
Details
The range of the input signal, specified as a two-element vector string, in volts. The first element determines the notch level of the input signal, and the second element determines the peak value. Parameter Input range (V) It is used to calculate the upper and lower thresholds for calculating the rise/fall time.
program usage
-
Use
get_param(gcb,"Range")to view the current parameter value Input range (V). -
Use
set_param(gcb,"Range",value)to set for the parameter Input range (V) a certain value.
