Hi all, I am trying to write a script that saves maxium and minimum value out of each 100ms of measurement to the file. Here's what I came up with: // Time settings Scope1.Time.Position.value = 0 Scope1.Time.Samples.value = 10000 Scope1.Time.Rate.value = 30000 Scope1.Time.Base.value = 0.1 // Channel 24V settings Scope1.Channel1.Range.value = 100 Scope1.Channel1.Attenuation.value = 10 // Channel 84V settings Scope1.Channel2.Range.value = 200 Scope1.Channel2.Attenuation.value = 10 Scope1.Trigger.Type.text = "Transition" Scope1.run() for(i = 0; i < 10; i++){ var file_CH1 = File("C:/AD_Data/Voltage_24V_"+i+".csv") var file_CH2 = File("C:/AD_Data/Voltage_84V_"+i+".csv") file_CH1.appendLine("Channel 1 Maximum value measurements day "+i) file_CH2.appendLine("Channel 2 Maximum value measurements day "+i) for(j = 0; j < 3600; j++){ var date = new Date() var time = date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds(); file_CH1.appendLine(time+","+Scope1.Channel1.measure("Maximum")) file_CH2.appendLine(time+","+Scope1.Channel2.measure("Maximum")) wait(0.1) } } Scope1.stop() The problem is that getting the time and saving data to the file takes a lot of time which is not constant. As a result I am getting from 2 to 4 measurements each second and loose some data. Do you have an idea how to do make it work?
