2.1 Output summary
The SPD1000X provides a floating output. The output rating of the
SPD1168X is 0-16 V / 0-8 A，while the output rating of SPD1305X is 0-30
V / 0-5 A;
Two modes of output: constant voltage (CV) and constant current (CC);
Two types of operation: two wire mode and remote sense mode.
Constant voltage output/constant current output:
In the constant current mode, the output current is a set value which can
be controlled by the front panel. The user interface displays the output mode
is ‘CC’ and the current is still in a set value. At this time, the voltage is lower
than the set value. When the output current is less than the set value, the
constant current mode will switch to constant voltage mode automatically.
In the constant voltage mode, the output current is less than the set value,
which can be controlled by the front panel. The user interface displays the
output mode is ‘CV’ and the voltage remains at the set value. When output
current reaches the set value, the system switches to the constant current
mode.
2-wire mode/remote sense mode:
When the SPD1000X is set to the 2-wire mode, the display prompt
displays the working mode as “2-wire.” When the output is on, the instrument
will detect and display the output terminal’s actual output mode automatically.
In the remote sense mode, the prompt displays the working mode as
“remote sense.” When the output is on and the remote sense terminal
connect to the load, the instrument will detect and display the actual output.

re-engage the output enable switch to resume normal output.
18 SPD1000X User Manual
SIGELNT
2.3 Remote Sense mode
When the power supply is outputting a large current, a voltage drop
can occur as a result of resistance in the output cable. To ensure an
accurate output voltage, the SPD1000X provides a 4-wire (remote
sense) mode of operation. In this mode, the voltage at the load terminal
is detected instead of the voltage at the power supply output. This
allows the instrument to automatically compensate for the voltage drop
caused by the load leads, ensuring that the user-specified voltage
output matches the voltage delivered to the load. Front panel Sense
connections are as shown below.
Operation method:
1、 Connect the output terminals and sense terminals
As shown above, connect the front panel output terminal and Sense
terminal to both ends of the load. When connecting, please pay
attention to polarity.
2、 Configure the voltage and current of output
a) Select the parameters to change by moving the direction of

SIGELNT
than the full version and includes only NI device drivers.
For example, you can download and install the full version of NI-VISA
5.4 at http://www.ni.com/download/ni-visa-5.4/4230/en/.
Next use the USB cable to connect the SPD1000X (via the rear
panel's USB Device connector) to the computer or use a network cable
to connect the SPD1000X (through the back-panel’s LAN connector) to
the computer's LAN.
Based on NI-VISA, the user can remotely control the SPD1000X in
two ways; one through the PC software EasyPower and the other
through custom programming with SCPI commands. For more
information, see Programming Examples.
Using Socket
Users can also use Socket through the network port and SPD1000X
for TCP/IP protocol-based communications. Socket communication is a
SPD1000X User Manual 37
SIGELNT
basic communication technology in computer networks. It allows
applications to communicate through network hardware and the
standard network protocol built into the operating system. This method
requires two-way communication between the instrument and the
computer network through an IP address and a fixed port number.
SPD1000X Socket communication port is 5025.
Using a network cable after connecting the SPD1000X (through the
rear panel LAN connector) to the local area network where the computer
is located, you can customize the programming with SCPI commands to
remotely control the SPD1000X. For more information, see
Programming Examples.
3.2 Grammar conventions
The SCPI command is a tree hierarchy that includes multiple
subsystems, each consisting of a root key and one or more level keys.
Command keywords are separated by a colon ":". The keywords are
followed by optional parameter settings. Commands and parameters are
separated by a space, and the parameters are separated by commas ",",
add a question mark "?", after the command line to inquire about this
function.
Most SCPI commands are a mixture of uppercase and lowercase
letters. Capital letters indicate abbreviations of shortened commands. For
better program readability, use the long commands convention. For
example,
[CH1:]VOLTage <voltage>
VOLT or VOLTage, uppercase and lowercase letters in any
combination will work. Therefore, VolTaGe, volt and Volt are acceptable.
Other formats such as VOL and VOLTAG will generate errors.
38 SPD1000X User Manual
SIGELNT
Brackets ({}) contain parameter choices. Brackets are not sent with the
command string.
Vertical line (|) separates parameter selections.
Angle brackets (<>) indicates that you must specify a value for the
parameter inside the brackets. For example, for the <voltage> parameter
in angle brackets for the above command, you must specify a value for
this parameter (for example, "CH1: VOLT 10"). Angle brackets do not
send angle brackets along with the command string.
Optional parameters are enclosed in square brackets ([]). If you do not
specify a value for the optional parameter, the instrument uses the default
value. For example, [CH1:] in the above command can be omitted (for
example, "VOLT 10"). At this time, the command will operate on the
current channel. Brackets are not sent with the command string.
