Output Groups represents the steps or groups that will be used. In the example above only one group is specified to  run as shown in column 1. So  Group 1 will output a voltage of  1 volt at 1 amp for  1 second. All other columns are grayed out. You can specify a maximum of 2048 groups.

One Cycle is one sequence of Groups. So you can repeat a sequence of Groups by setting the Cycle setting between 1 and 99999. You can also save and restore timer setups from this  menu page as well as set the End State. The End State can be set to last or off.
 
Trigger Mode can be specified  as Single or Auto. When Single is specified the power supply will output one group at a time and will increment to the next group when the OK button is pressed. When Auto is selected the complete sequence of groups will be run.

End State can be selected to Output Off or Last. With Output Off selected the power supply will turn the output off when the last group is completed. When Last is selected the power supply will maintain the settings of the last group that is completed.

To start the sequence of groups press the On/Off button.

When the timer is enabled the power supply will output preset voltage and current values at time increments you specify.

Press Timer and then Timer Set to see the screen below. The columns 0-5 represents steps or groups that will be output at the Set time in seconds. So for this example only column 0 will be output since the Group field has been set to 1.

The channel currently selected is displayed in the status bar. Press the channel selection keys at the front panel to select the channel you wish to program. Then press Parameter to select voltage current and time duration for each group. Groups 0 through 5 can be seen on the screen and you can program as many as 2048 Groups.

Once you have programmed the voltage, current and time for each Group then go to page 2/3. Here you can specify Cycles. One Cycle is one sequence of Groups. So you can repeat a sequence of Groups by setting the Cycle setting between 1 and 99999. You can also save and restore timer setups from this  menu page as well as set the End State. The End State can be set to last or off.

From menu page 2/3 increment to 3/3 and then press the left arrow at the bottom of the display to  get to the Timer and Delayer interface:

To enable the timer and output the programmed levels first turn Timer On and then press the On button of the channel  that has been programmed. Once turned on the power supply will output each group that has been programmed.

The power supply also has a collection  of templates  that will output voltage and current to a set pattern. They include  Sine, Pulse, Ramp, Stair Up, Stair Dn, StairUpDn, Exp Rise and Exp Fall.

The DO800 series allows you to easily lock and unlock the instrument’s front panel by pressing and holding on the OK button in the bottom right hand corner of the front panel.  When the instrument is locked the only buttons that are fully function are the individual channel On/Off buttons otherwise the rest will not respond.  To unlock the instrument, you need to press and hold the OK button just like with locking the instrument. 


The instrument also comes with the ability to implement a password requirement when Unlocking the instrument, it will not require a password to lock the instrument.  To enable this feature press Utility -> Systemv – > Arrow over to page two -> Key Lock.  When this feature is turned on the instrument will require the user to enter 2012 before the instrument will be unlocked.

DP800 series power supply provides the following options:
    High Res: 1mV/1mA Resolution option for the DP800 Family
    Interface: RS2322 and LAN interface option for DP800 Family
    AFK: Detect and Analyze option for the DP800 Family
    Digital IO: Four Channels for trigger in and out option for the DP800 Family

To install an option, you need an option license (each instrument has a unique license). The option license is a 28-character string, which consists of English letters and numbers. After you purchase an option, you will obtain a key (used for obtaining the option license). You can then install the option using the following steps.

(1) At the bottom of https://www.rigolna.com/ look for the license activation link:
https://licenseen.rigol.com/CustomerService/ProductRight_EN
 
(2) In the interface, enter the correct key, serial number and verification code. Then click Generate to obtain the option license.
Note: The hyphens in the option license should be omitted.

(3) Press Utility and then arrow over to the second page and then option. 

(4) Press the Install key to enter the license input screen:

(5) In the License Input interface, press the Up/Down/Left/Right arrow key or use the knob to select the desired character (the English letter is not case-sensitive) on the virtual keypad, and then press Select to enter the character. The entered characters will be displayed in the “License Input Area”. While entering the characters.
Note: The hyphens in the option license should be omitted.

(6) After inputting a license, select “OK” on the virtual keypa. If the option has been successfully installed, a prompt message will be displayed.

The track capability allows the DP800 to have channel 1 and channel 2 create the same amount of power while only changing one channel, this allows customers to quickly adjust their desired power.  To enable this feature you need to press the Track button on the bottom right hand side of the display when presented with the main working window.  With Track enable both channel 1 and channel 2 will create the same power.

Pin 8 of the RS232 interface on the rear panel is used to receive the external trigger input signal. When it receives a high level signal (≥ 2.1 V, 10 mA), the channel output will be turned on. If 8 volts or greater is applied damage to the power supply I/O circuit can result.

The DP800 can load Timer files that are created externally, these timer files need to be saved as CSV files and can be created using Excel.  Below shows an example of a timer file.  Note that the file cannot exceed 2048 steps.

The timer function can be used on the DP800A or the DP800 series if a Timer option has been installed.

To create a Timer file on the instrument, press the “Timer” button and then press “Timer Set”.  Once you are in the Timer Set to enter a value you need to press the “Parameter” then to navigate to your desired cell use the arrow buttons to the right and then use the number pad to enter your desired value. Increase the number of Steps use and to navigate through the Steps use the up and down around on the display.

To save a timer file arrow over to the second page of the Timer Set menu and then press save and with in this menu you will be able to save the Timer file either internally or onto a flash drive.

To load the timer file from the Timer Set menu arrow over to the third page of the Timer Set menu and then press the back button.  Next turn on the timer and the power supply will start to step through your desired current and voltage requirements for each step.

The DP700 series power supplies have a single serial I/O port. If you plan on programming the DP700 power supply from a PC you will need a USB to serial cable.

An example is pictured here:

This particular cable is from Trendnet and has TU-S9 printed on it and has a male serial connector. It’s approximately 26” in length. A search for “Trendnet TU-S9” will bring up multiple sources to order from. The DP700 power supplies have a female serial connector so a gender changer will be necessary accessory as well.
