1Characteristics
High-resolution and high-precision output
The highest resolution of 1mV/1mA (SPD3303X), provides excellent setting and read back accuracy.
This ensures accurate output even with very with small changes in voltage or current. This is
impossible for a low resolution power supply.

Series / parallel / independent mode function
Series and parallel function allows two channels combined into one output with more power output
capability, extending the application range. Each of 3 channels power can be turned on or offindependently and also can be turned all on or all off.

Panel displays the timing output
Through front panel operation, 5 groups of timing settings and output control can be displayed, which
provides users a simple power programming function. Also a connection can be made with Siglent’s
EasyPower PC software providing a full range of communication and control requirements.

production and services of electronic test & measurement instruments.

SIGLENT first began developing digital oscilloscopes independently in 2002.
After more than a decade of continuous development, SIGLENT has extended
its product line to include digital oscilloscopes, isolated handheld

oscilloscopes,

function/arbitrary

waveform

generators,

RF/MWsignalgenerators, spectrum analyzers, vector network analyzers, digital multimeters,
DC power supplies, electronic loads and other general purpose test
instrumentation. Since its first oscilloscope was launched in 2005, SIGLENT
has become the fastest growing manufacturer of digital oscilloscopes. We
firmly believe that today SIGLENT is the best value in electronic test &measurement.
