Output summary
SPD3303X/3303X-E have three independent outputs, two of which are adjustable in voltage value
and the other one includes selectable 2.5V, 3.3V or 5.0V

Independent / Parallel / Series
SPD3303X/3303X-E have three output modes: independent, parallel and series, which can beselected through the track switch on the front panel. In the independent mode, the output current andvoltage are controlled respectively. In the parallel mode, the current value is twice that of the single
channel. In the series mode, the voltage value is twice that of the single channel.

Constant voltage / current
In the constant current mode (independent or tracking mode), the current value is rated and controlled
through the front panel. The indicator light displays red and the voltage value is under rating. It will
return to constant voltage mode when the current value is under dating.

In the constant voltage mode, the current value is less than the setting value, and the voltage value
is controlled through the front panel. The indicator light displays yellow and the current value ismaintained at the set value. It will return to constant current mode when the voltage value is underdating.

24

SPD3000X Quick StartRemote control
SPD3303X/3303X-E support communication with computer through USB and LAN interface on therear panel.
SCPI (Standard Commands for Programmable Instruments) is an ASCII-based programming
language, which can be used to control power supply remotely by computer installed with EasyPowersoftware or NI (Measurement & Automation).
In this chapter, we mainly introduce and illustrate the SCPI SPD3303X/3303X-E support

Syntax Conventions
Most commands are a mixture of upper- case and lower-case letters. The upper-case letters indicate
the command's abbreviated spelling, which yields shorter program lines. For better program
readability, use the long form. For example:[{CH1|CH2}:]VOLTage <voltage>
For the keyword VOLTage, you can type VOLT or VOLTage in any combination of upper- or lowercase letters. Therefore, VolTaGe, volt and Volt are all acceptable. Other forms, such as VOL and
VOLTAG, will generate an error.
⚫

Braces ( { } ) enclose the parameter choices. The braces are not sent with the command string.

⚫

A vertical bar ( | ) separates parameter choices. For example, {CH1|CH2} in the above commandindicates that you can specify a channel. The bar is not sent with the command string.

⚫

Angle brackets ( < > ) indicate that you must specify a value for the enclosed parameter. For
example, the above syntax statement shows the <voltage> parameter in angle brackets. You
must specify a value for the parameter (for example " CH1:VOLT 10"). The angle brackets are
not sent with the command string.

⚫

Optional parameters are enclosed in square brackets ( [ ] ). If you do not specify a value for an
optional parameter, the instrument uses a default value. For example, {CH1|CH2} in the above
command can be omitted (for example, "VOLT 10"). In this case, the command would word on
the current channel. The brackets are not sent with the command string.

Troubleshooting
Question 1:

What to do if a short circuit on output terminal occurs?

Answer 1:

There are over current protection and short circuit protection inside the power,
so current will be controlled in safety range.

Question 2:

Is it abnormal that the CH3 overload indicator is lit?

Answer 2:

No, that only means the current value reaches 3.2A, which is the maximum value
within its range, and now power supply can be used continuously with thesuggestion that decrease the output load.

Question 3:

Is it normal that in the series mode, voltage and current value of a channel isrespective 0V and not 0A, while that of another channel are both not 0?

Answer 3:

Yes, because when current output load is higher than the limited current value,
the working mode turns to CC from CV.

Question 4:

How to deal with the upgrade failed?

Answer 4:

Upgrade via guide procedure can be used if the upgrade failed (see detail in“2.11 Upgrade firmware”).

Question 5:

Why the practical value is not the same with the set value (over performancestandard) and even changes slowly on startup?

Answer 5:

It’s normal. On startup, components inside the instrument are in the process ofgetting stable and readings will be stable about 30 minutes later.

Question 6:

What if the circuit air switch turns off automatically when power on?

Answer 6:

First of all, make sure whether the rating of the air switch is proper or not (Forinstance: the rating of air switch B and C should be respectively over 16A and
10A). If the failure still exits beyond the reason, check if there is a short circuit,or return it to the factory to have it repaired by qualified personnel.

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, 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.
