The consigner or carrier will be responsible for damages to the instrument resulting from shipment. SIGLENT would not provide free maintenance or replacement. 2. Inspect the instrument. If there are instruments found damaged, defective or failure in electrical and mechanical tests, please contact SIGLENT.
SIGLENT Safety Considerations To ensure that the instrument can work normally, please conduct necessary inspection before using the SPD3303C. Input Power Requirement The SPD3303C allows a 50Hz/60Hz frequency, and four levels of AC power: 100V/120V/220V/230V. You can select wanted power voltage with the “DIP Switch ”...

SIGLENT Output Checking To make sure the instrument can correctly respond to operation from the front panel, please perform the output checking, which includes voltage checking when all channels are with no load and current checking when short circuit occurs.
SIGLENT Chapter 2 Control Panel Operation n this chapter,the function and operation of SPD3303C control panel will be introduced in detail to give you an all-around understanding of it. Brief introduction Output Summary CH1/CH2 Independent Output CH3 Independent Output Parallel Output...
SIGLENT Output Summary SPD3303C is designed with three independent outputs, two of which are adjustable in voltage value and the other includes a set of selectable voltage values: 2.5V, 3.3V or 5.0V. Independent/Parallel/Series SPD3303C has three output modes: independent, parallel and series that could be selected through the track switch on the front panel.
SIGLENT CH1/CH2 Independent Output Instruction CH1 and CH2 are working in independent mode and insulated from the ground. Output ratings 0~30V/0~3A (Max: 32V, 3.2A) Operation steps 1. Make sure that parallel/series mode is off. 2. Connect load to the positive and negative terminals of CH1/CH2.
SIGLENT CH3 Independent mode Instruction CH3 works independently from CH1, CH2, and its voltage and current ratings are: 2.5V, 3.3V, 5V, 3A. Output ratings 2.5V/3.3V/5V, 3A Operation steps: 1. Connect the load to the positive and negative terminal of CH3 channel.
SIGLENT CH1/CH2 Series Mode Instruction:In the series mode, CH1 and CH2 are linked internally into one channel controlled by CH1. The output voltage value is twice compared with that of single channel. Output ratings 0~60V/0~3A (Max: 64V, 3.2A) Operation steps:...
SIGLENT CH1/CH2 Parallel Mode Instruction In the parallel mode, CH1 and CH2 are linked internally into one channel controlled by CH1. The output current value is twice as much as the single channel. Output ratings 0~30V/0~6A (Max: 32V, 6.4A) Operation steps: 1.
SIGLENT Save and Recall Five groups of setups can be saved in memory. Contents of setups including: Independent/series/parallel mode Output voltage/current value Steps for saving setup 1. Set the state needed to save; 2. Press SAVE to enter the save interface;...
SIGLENT Version Upgrade The software of the instrument is upgraded with a fixed name file via PC management software with USBTMC. The upgrade method is below: Upgrade in normal Interface 1. Open the EasyPower software after correct connection of the USB cable with the instrument.

SIGLENT Upgrade via the Guiding Procedure Upgrading via the guiding procedure can be used if the upgrading method above failed. Specific steps: 1. Pressing the knob prior to power on the instrument to enter the guiding procedure mode. 2. As shown in figure 2, select the “Firmware Mode” option instead and the following upgrading steps are the same as method 1.
SIGLENT Chapter 3 Remote Control SCPI Commands can be used to conduct remote control on the SPD3303C Power Supply through the USBTMC. To realize the remote control, the installation of EasyPower or NI (Measurement & Automation ) software for the computer is required prior to connecting the instrument with it using an USB cable.
