' RESET - This command puts the oscilloscope into a known
' state. This statement is very important for programs to
' work as expected.
' commands are initialized by *RST.
' reinitialize them unless the default setting is not suitable
' for your application.
' Reset the to the defaults.

' Clear the status data structures.

' IDN - Ask for the device's *IDN string.

' AUTOSCALE - This command evaluates all the input signals
' and sets the correct conditions to display all of the
' active signals.
oscp.DoCommand(":AUToscale")
' CHANNEL_PROBE - Sets the probe attenuation factor for the
' selected channel.
' 0.1 to 1000.
oscp.DoCommand(":CHANnel1:PROBe 10")
' CHANNEL_RANGE - Sets the full scale vertical range in volts.
' The range value is eight times the volts per division.
oscp.DoCommand(":CHANnel1:RANGe 8")
' TIME_RANGE - Sets the full scale horizontal time in seconds.
' The range value is ten times the time per division.
oscp.DoCommand(":TIMebase:RANGe 2e-3")
' TIME_REFERENCE - Possible values are LEFT and CENTER:
' - LEFT sets the display reference one time division from
' the left.
' - CENTER sets the display reference to the center of the
' screen.
oscp.DoCommand(":TIMebase:REFerence CENTer")
' TRIGGER_SOURCE - Selects the channel that actually produces
' the TV trigger.
oscp.DoCommand(":TRIGger:TV:SOURCe CHANnel1")
' TRIGGER_MODE - Set the trigger mode to, EDGE, GLITch,
' PATTern, CAN, DURation, IIC, LIN, SEQuence, SPI, TV,
' UART, or USB.
oscp.DoCommand(":TRIGger:MODE EDGE")
' TRIGGER_EDGE_SLOPE - Set the slope of the edge for the
' trigger to either POSITIVE or NEGATIVE.
