This chapter contains a brief introduction to GPP3060/GPP-6030 including the main features and an overview of the front and rear panel. Use the Getting Started chapter on page 27 to start up instructions and how to setup the appropriate operation environment.

Introduction

Overview
Independent / Tracking Series / Tracking Parallel

The GPP-3060/GPP-6030 regulated DC power supply series are adjustable, multifunctional work stations. It has three independent outputs: two with adjustable voltage levels and one with fixed level selectable from 1.8V, 2.5V, 3.3V and 5V.
It can be used for logic circuits where various output voltage or current are needed, and for tracking mode definition systems where plus and minus voltages with insignificant error are required.
The three output modes of it, independent, tracking series, and tracking parallel, can be selected through pressing the TRACKING key on the front panel. In the independent mode, the output voltage and current of each channel are controlled separately. The isolation degree, from output terminal to chassis or from output terminal to output terminal, is DC500V.
In the tracking modes, both the CH1 and CH2 outputs are automatically connected in series or parallel; no need to connect output leads. In the series mode, the output voltage is doubled; in the parallel mode, the output current is doubled.

GPP-3060/6030 User Manual

Load Mode

It has additional Load function on both CH1 & CH2 with 3 modes: CV (Constanct Voltage), CC (Constant Current) and CR (Constant Resistance), all of which can be selected through the function keys on the front panel. Voltage, current and resistance can be well regulated in each mode, respectively.

Constant Voltage/ Constant Current

Each output channel is completely transistorized and well-regulated, and works in constant voltage (CV) or constant current (CC) mode. Even at the maximum output current, a fully rated, continuously adjustable output voltage is provided. For a big load, the power supply can be used as a CV source; while for a small load, a CC source. When in the CV mode (independent or tracking mode), output current (overload or short circuit) can be controlled via the front panel. When in the CC mode (independent mode only), the maximum (ceiling) output voltage can be controlled via the front panel. The power supply will automatically cross over from CV to CC operation when the output current reaches the target value. The power supply will automatically cross over from CC to CV when the output voltage reaches the target value. For more details about CV/CC mode operation, see page 26.

Automatic tracking mode

The front panel display (CH1, CH2) shows the output voltage or current. When operating in the tracking mode, the power supply will automatically connect to the auto- tracking mode.

OVERVIEW

Display Change Function

It provides up to 6 display types, each of which can be well selected via setting. For details, see page 33.

Output Waveform Function

Under Source mode, user can customize a certain V/I sequential waveform output. Under Load mode, it is programmable for dynamic load (below 1Hz). For details, see page 54.

Front and rear output function

For the convenience of customers, GPP can be operated by the panel menu or remote command, so that it can be output on the front and rear panels, please refer to page 31.

Constant Voltage/Constant Current Crossover CharacteristicsGETTING

STARTED

Background CV mode
Constant Current Mode

The unit will switch automatically between constant voltage and constant current according to changes in the load.
When the load current is less than the current setting, the unit operates in constant voltage mode, changing the current level according to the load but maintaining the set voltage level until the current reaches the set current level. The status indicator will show CV on the LCD when in CV mode.
When the output current reaches the set current level, the unit switches operation to constant current mode. The status indicator will show CC on the LCD display. In CC mode, the current level is maintained and the voltage level is limited to less than the set voltage level to limit the output power from an overload. When the current drops below the set current level, the unit will revert back to CV mode.

Command Syntax
The commands that are used with the GPP meet IEEE488.2 and SCPI standards.
SCPI Commands Overview SCPI
Command Format SCPI is an ASCII based command language designed for test and measurement instruments. SCPI commands uses a hierarchical structure (tree system), and is divided into different subsystems. Each subsystem is defined by a different root keyword. Each command consists of a root keyword and one or more hierarchical key words separated by a colon “:” and followed by a parameter. There is always a space between the keywords and the parameters. Any commands followed by a question mark (?) are queries.
For Example: :SYSTem:BEEPer:STATe {0|1|OFF|ON} :SYSTem:BEEPer:STATe?
SYSTem is the root level keyword and BEEPer and STATe are the secondary and tertiary level keywords. All levels have a “:” separating each keyword. Parameters are enclosed in “{ }”. The commands SYSTem:BEEPer:STATe has {0|1|OFF|ON } as parameters. The parameters are separated with a space. SYSTem:BEEPer:STATe? indicates that the command is a query. In addition some commands have multiple parameters that are usually separated by a comma “,”. For example: :STATus:QUEue:ENABle (-110:-222, -220).
116

REMOTE CONTROL
Symbol Description SCPI commands have the following conventional symbols. These symbols are not commands but are used to describe the command parameters.
1. Curly Brackets { } Curly Bracket enclose command string parameters, for example: {OFF|ON}
2. Vertical Bars | Vertical bars are used to separate one or more optional parameters. Only one command can be selected. With the following two parameters, {ON|OFF} only ON or OFF can be selected.
3. Square Brackets [ ] The contents inside square brackets represent keywords or parameters that can be omitted when executing a command. For example: For the commands :OUTPut[:STATe] {ON|OFF}, [STATe] can be omitted.
4. Angle Brackets < > The parameters in angle brackets must be substituted with a valid parameter. For example: For the command :DISPlay: CONTrast

, must be use a numerical value instead such as, :DISPlay:CONTrast 1 117

Parameter Types

GPP-3060/6030 User Manual

The commands have a number of different parameter categories. How the parameters are set depend on the parameter categories.

1. Boolean Commands parameter that have to states “OFF” and “ON”, for example, DISPlay:FOCUs {ON|OFF}. “ON” will turn on the focus display function, while “OFF” will turn it off.

2. Consecutive Integers Parameters that use consecutive integers, for example: For the command :DISPlay:CONTrast , is an integer value with a range of 1~3.

3. Continuous Real Number Parameter that must be a continuous real number can have any value within the effective range and accuracy. For example: The command CURRent {|MINimum|MAXimum}, is used to set the current value for the current operating channel. can be any value within the setting range of the current channel.

4. Discrete For discrete parameters, only those values that are listed can be used. For example: The *RCL {0|1|2|3|…|9} command can only use 0, 1, 2, 3, …, 9.

118

REMOTE CONTROL 5. ASCII Strings
ASCII string parameters must use a combination of ASCII characters in a string. For example: For the command: MODE , must be an ASCII string.
Command Abbreviations The syntax for SCPI commands contains a combination of upper and lower case letters. The upper case letters in a command represent the short form of that command. Commands are not case sensitive and can used in both upper and lower case. Note, however, to use the short form of the command, only the capital letter part of the command can be used (no other abbreviation can be used). For example:
:MEASure:CURRent? Can be abbreviated to: :MEAS:CURR?
Command Terminators When sending a command to the function generator, the command must be terminated with a character. The IEEE-4888 EOI can also be used as a character. A command can also be terminated using a carriage return + character. The command path will always be reset back to the root level after a command has been terminated. Return values are terminated with 0x0A.
