Series 2200 Multi-Channel Power Supplies
Quick Start Front Panel and Programming Operation Guide


Introduction

This operating guide describes front panel operation and corresponding SCPI command code to perform
essential functions of the model 2230-30-1 Triple Channel Power Supply and the model 2220-30-1 Dual
Channel Power Supply. References to the third channel specifically apply to the model 2230-30-1 triple
channel power supply.


Single Channel Operation

The series 2200 multi-channel power supplies have all channels enabled in their default state. However,
any channel can be disabled and enabled independently. The following example demonstrates the steps
to enable and output a voltage on channel 2.

Front Panel Operation
STEP 1 Enabling Channel 2
1. Press Menu.
2. Use the arrow keys or the navigation wheel to select Enable Channels.
3. Press Enter to enter the submenu.
4. Use the arrow keys or the navigation wheel to select Enable/Disable CH2.
5. Press Enter to enter the submenu.
6. Use the arrow keys or the navigation wheel to select Enable CH2 (default).
7. Press Enter to enable channel 2.
8. Press Esc a couple of times to return to the main display.

STEP 2 Setting the Output Voltage on Channel 2
9. Press CH2.
10. Press V-Set.
11. Use the arrow keys, numeric keypad, or the navigation wheel to enter the desired voltage
output value. If using the arrow keys or the navigation wheel, use the left arrow key to highlight
the digit that represents the resolution for adjustments.
12. Press Enter to set the voltage.

STEP 3 Setting the Current Limit on Channel 2
13. Press I-Set.
14. Use the arrow keys, numeric keypad, or the navigation wheel to enter the current limit. If using
the arrow keys or the navigation wheel, use the left arrow key to highlight the digit that
represents the resolution for adjustments.
15. Press Enter to set the current.

STEP 4 Turning on the Output
16. Press Output On/Off to turn on the output.

Remote Operation

The following SCPI command example enables channel 2, sets the voltage output to 2.22V, the current
limit to 1.5A and turns the output on.

INST:SEL CH2
SOURCE:OUTP:ENAB ON
SOURCE:VOLT 2.22V
SOURCE:CURR 1.5A
SOURCE:OUTP ON


Combining Channels 1 and 2 in Series to Output More than 30V

The series 2200 multi-channel power supplies have all channels isolated in their default state. However,
channel 1 and channel 2 can be combined in series to output a higher total voltage. The following
example demonstrates the steps to enable and output a combined voltage from channel 1 and 2.

Front Panel Operation
STEP 1 Configure the Instrument to Series Combination
1. Press Menu.
2. Use the arrow keys or the navigation wheel to select Combine CH1+CH2.
3. Press Enter to enter the submenu.
4. Use the arrow keys or the navigation wheel to select V1+V2 Series.
5. Press Enter to set to series combination. See an example of a series combination front panel
display below.






STEP 2 Setting the Voltage Output and the Current Limit
6. Press CH1.
7. Press V-Set.
8. Use the arrow keys, numeric keypad, or the navigation wheel to enter the voltage output.
9. Press Enter to set the voltage of the combined channels.
10. Press I-Set.
11. Use the arrow keys, numeric keypad, or the navigation wheel to enter the current limit.
12. Press Enter to set the current of the combined channel.

STEP 3 Turning on the Output
13. Press Output On/Off to turn on the output.

Remote Operation

The following SCPI command example configures the power supply for the series combination mode,
sets the voltage output to 36V, the current limit to 1.5A and turns the output on.

INST:COM:SER
SOURCE:VOLT 36V
SOURCE:CURR 1.5A
SOURCE:OUTP ON

Wiring Channels 1 and 2 in Series to the DUT

Connect two wires from either the front panel binding posts or the rear panel terminals, as shown in
Figure 1 below, to your device under test (DUT). The SENSE lines are optional (rear panel only) and are
used in a remote sense connection.

Combining Channels 1 and 2 in Parallel to Output More than 1.5A

The series 2200 multi-channel power supplies have all channels isolated in their default state. However,
channel 1 and channel 2 can be combined in parallel to output a higher total current. The following
example demonstrates the steps to enable and output a combined current from channel 1 and 2.

Front Panel Operation
STEP 1 Configure the Instrument to Parallel Combination
1. Press Menu.
2. Use the arrow keys or the navigation wheel to select Combine CH1+CH2.
3. Press Enter to enter the submenu.
4. Use the arrow keys or the navigation wheel to select I1+I2 Parallel.

5. Press Enter to set to parallel combination. See an example of a parallel combination front panel
display below.






STEP 2 Setting the Voltage Output and the Current Limit
6. Press CH1.
7. Press V-Set.
8. Use the arrow keys, numeric keypad, or the navigation wheel to enter the voltage output.
9. Press Enter to set the voltage of the combined channel.
10. Press I-Set.
11. Use the arrow keys, numeric keypad, or the navigation wheel to enter the current limit.
12. Press Enter to set the current of the combined channel.

STEP 3 Turning on the Output
13. Press Output On/Off.

Remote Operation

The following SCPI command example configures the power supply for the parallel combination mode,
sets the voltage output to 30V, the current limit to 2.9A and turns the output on.

Wiring Channels 1 and 2 in Parallel to the DUT

Connect two wires from either the front panel binding posts or the rear panel terminals, as shown in
Figure 2 below, to your DUT. The SENSE lines are optional (rear panel only) and are used in a remote
sense connection.
