The following SCPI programming example shows how to set
the counter mode.
// Supply the signal to COUNT301_CLK
-> COUN:FUNC TOT,(@301)
-> COUN:GATE:SOUR INT,(@301)
-> COUN:CLK:POL AHI,(@301)
-> COUN:CLK:SOUR EXT,(@301)
-> COUN:TOT:IVAL 100,(@301)
-> COUN:TOT:UDOW:DIR UP,(@301)
-> COUN:TOT:UDOW:SOUR INT,(@301) // Set the Up/Down source
-> SOUR:COUN:OUTP:POL AHI,(@301)
-> COUN:TOT:INIT (@301)
-> MEAS:COUN:TOT? (@301)
<- 100
-> MEAS:COUN:DATA? (@301)
<- 100
-> COUN:GATE:CONT ENAB,(@301)
-> COUN:GATE:CONT DIS,(@301)
-> MEAS:COUN:TOT? (@301)
<- 105
-> MEAS:COUN:DATA? (@301)
<- 105
-> COUN:ABOR (@301)
-> COUN:TOT:CLE (@301)
-> MEAS:COUN:TOT? (@301)
<- 0
-> MEAS:COUN:DATA? (@301)
<- 0
