Simplify complex sequencing using the list operation function
You can generate complex load sequences quickly using the list operation function. Here, you can edit the setpoints, dwell time, and slew rate for each step in thetest. *Slew rate can only be edited in CC mode.

4-wire SENSE compensation mode function
In CC/CV/CR/CW mode, when a load is connected to a power supply, it
will cause a large voltage-drop on the connection lines between tested
instrument and terminals of load. Using remote sense, you can measure
the voltage at the DUTs input terminals, effectively removing theadditional error due to the voltage drop in the connection wires.

About SIGLENTSIGLENT is an international high-tech company, concentrating on R&D, sales,
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, function/arbitrary waveformgenerators, RF generators, digital multimeters, DC power supplies, spectrum
analyzers, vector network analyzers, isolated handheld oscilloscopes,
electronic load and other general purpose test instrumentation. Since its ﬁrst
oscilloscope, the ADS7000 series, was launched in 2005, SIGLENT has become
the fastest growing manufacturer of digital oscilloscopes. We ﬁrmly believethat today SIGLENT is the best value in electronic test & measurement.
