Hi,
We are doing noise measurement of power rails using DSOX3024A.
Process is :
Connect the rail's voltage to Scope.
Change the offset and vertical divisions to display waveform in Top 3 Divisions (approx)
Apply FFT
Put the statistics measurements ON wait for at least count to 1000
Then take the snapshot.
This we are trying to do using Remote Control using USB.
I can able to display the voltage rail in TOP 3 Divisions.
I can't able to Turn ON the Statistics measurements using commands.
Lines used for displaying the statistics(Note : dsoObj -> is the DSOX3034A Object returned by ResourceManager.get_instrument())
dsoObj.write("MEASure:STATistics:DISPlay ON");
dsoObj.write('MEASure:STATistics:RESEt')
I have Statistics Display on Screen which doesn't got answer for this.
dsoObj.write("MEAS:STAT:MCO 1000")
dsoObj.write("MEAS:STAT MCO")
count = float(dsoObj.ask("MEAS:RES?"))
while (count<1000):
count = float(dsoObj.ask("MEAS:RES?")
dsoObj.write("MEAS:STAT ON") # sets the RES? query to return all stats, or change this to whatever you want to measure.
data = dsoObj.ask("MEAS:RES?") # then you have a measurement string, comma separated.
data = data.split(',') #creates a list of meas type, min, max, mean, stdev, and ct
dsoObj.write("MEAS:STAT:RES") #resets the stats, counts = 0.
