The :CONTrol{1-16}:AOUT subsystem commands allows the user to specify the rear panel output mode, and then set appropriate voltage levels, pulse types, and ports for that mode. When all parameters are entered, a single command allows the rear panel output to be toggled on and off. The settings are saved and can be recalled with the four setup file types:
For example, to set the Rear Panel Output Mode at Horizontal, follow the general sequence below. In this example, the control is for Channel 4 with a Start voltage of -1.5 V and a Stop voltage of 2.8 V.
1. Turn the Rear Panel Output off:
:CONTrol4:AOUT:STATe OFF
2. Set the Output Mode to HORizontal:
:CONTrol4:AOUT:MODE HORizontal
3. Set the Horizontal Output Mode start (STARt) voltage to -1.5 V:
:CONTrol4:AOUT:VOLTage:STARt -1.500
4. Set the Horizontal Output Mode stop (STOP) voltage to +2.8 V:
:CONTrol4:AOUT:VOLTage:STOP 2.800
5. Check voltage settings:
:CONTrol4:AOUT:VOLTage:STARt?
-1.500
:CONTrol4:AOUT:VOLTage:STOP

:CONTrol{1-16}:AOUT:MODE?
Description
For the indicated channel, the command sets the Rear Panel Output mode to horizontal, driven, or TTL where:
• HORizontal = Defines the rear panel output voltage to be proportional to the horizontal position on the screen. If HOR is set, the Start and Stop voltages must by set, where the Start Voltage is the voltage for the first sweep point, and the Stop Voltage is the voltage for the last sweep point. The Start Voltage can be higher than, equal to, or less than the Stop Voltage. The voltage range for each is -10 VDC to +10 VDC. The Start Voltage is set by the :CONTrol{1-16}:AOUT:VOLTage:STARt command while the Stop Voltage is set by the :CONTrol{1-16}:AOUT:VOLTage:STOP command (both described below).
• DRIVen = Defines the rear panel port analog output voltage as a function of the currently driven port. For example, if Port 1 is driving, the selected voltage is that set for Port 1. If Port 2 is driving, the selected voltage is that set for Port 2. If DRIV is set, the Output Level Voltage for Port 1 or Port 2 must be set. The command :CONTrol{1-16}:AOUT{1-2}:DRIVen:LEV sets the driven port voltage level for the indicated channel and port with a voltage range of -10 VDC to +10 VDC.
• TTL = Defines the TTL power for each port as steady state high or low, or as pulse high or low. If pulse is selected, the duration of the pulse is also defined. The command :CONTrol{1-16}:AOUT{1-2}:TTL:TYPe defines the TTL type used as HIGH (+5 VDC), LOW (0 VDC), HIGH PULSE (+5 VDC), or LOW PULSE (0 VDC). If High Pulse or Low Pulse is selected, the Pulse Width in seconds must be specified using the command :CONTrol{1-16}:AOUT:PULSe:WIDth. Note that the TTL type is defined separately for Port 1 and for Port 2.
Once configured, use the command :CONTrol{1-16}:AOUT[:STATe] <ON | OFF | 0 | 1> to toggle the rear panel on and off. The query outputs the currently set Rear Panel Output mode on the indicated channel.
