OVERVIEW

Overview

The PPH-1503 is a portable high-speed programmable DC power supply with flexible operating configurations. In addition to the basic power supply functionality, it is also able to measure pulse current and the average current over long periods of time.

The PPH-1503 is designed for testing the power consumption of battery powered wireless communication devices (e.g. cell phones). Such devices often have large load variations within a short time span. The high precision power supply has excellent voltage stability during pulsed loads and is capable of simultaneously measuring the pulse current, even for very short pulses. In addition, the power supply is able to sink current, allowing it to simulate the characterics of a discharged rechargeable battery for testing chargers and charge control circuits.

OVERVIEW

Background

The unit will switch automatically between constant voltage and constant current according to changes in the load.

CV mode

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.

Constant Current 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.

Description

Changes in the load current allows us to measure the pulse current.

There are three ways that pulse current can be measured:

1. Measuring the peak current over a single cycle (High Measurement).

2. Measuring the trough current over a single cycle (Low Measurement).

3. Measuring the average current over a single cycle (Average Measurement).

Pulse Current Measurement

PPH-1503 User Manual

The high and average measurements are triggered by the rising edge of the pulse current are performed for the time specified for the measurement.

Low measurement is triggered by the falling edge of the pulse current.

Note: Pulse current measurement is only valid up

to 5A.

Parameter Description

IntTime

 Integration Time.  The integration measurement time

can be set to automatic or to one of the manual settings (High Time, Low Time, Aver Time).

 When the integration

measurement time is set to automatic mode, the system will measure the peaks and troughs of the pulse current and will automatically set an appropriate intergration time. The average integration time is the time of all the accumulated peaks and troughs. After the setting the integration time to automatic, the setting will apply to all subsequent pulse measurements, unless the automatic integration mode is applied again or the integration time is manully set. The automatic

BASIC OPERATION

Integration time can automatically detect pulses in the 80uS to 833mS range.

 The manual time range setting is

33uS to 833333uS. The default units are in microseconds (uS). The unit will automatically round down the last two digits to 00, 33 or 66 micoseconds. For example, for a value of 65.999, it will be rounded down to 33 and 66.01 will be rounded down to 66.

TrigDelay

 Trigger Delay  When a pulse is detected, there

will be a 25us code execution delay time. The trigger delay settings are used to filter out the current overshoot. Measurement will begin from after the trigger delay time. The trigger delay setting range is: 0~0.10000S, with a resolution of 0.00001S. The setting units are in seconds.

AverRead[3]

 Average Reading Count: Reads

back the average number of displayed values.

 This parameter is only applicable

for pulse current measurement. The average number range can set from 1 ~ 100 with a resolution of 1.

PPH-1503 User Manual

TrigLeve[3]

 Trigger Level.  To avoid false pulse

measurements, the trigger level can be set close to the current amplitude. All noise and transient currents that are below the trigger level will be ignored. The trigger level has a setting range of 0 to 5A, with a resolution of 5mA. The setting unit for the trigger level is in amps (A). This setting is only valid for pulse measurements.

BASIC OPERATION

Description

The long current integration measurement function measures the mean (average) current over a single or multiple current pulses. The long integration time period must be a full period or integer multiples of a complete period of the measured pulse current. The Long integration measurement calculates the whole integration time as an integer number of integration cycles. An integration cycle is the line cycle period plus the data processing time. For example, if the line frequency is 60Hz, then a single integration cycle is 16.7mS, if the frequency is 50Hz, then a single integration cycle is must be 20mS. Long integraton is one of the methods to extend A/D circuits to exceed beyond their maximum integration time. The A /D conversion circuits can measure a pulse of up to 833 mS. Long integration measurement extends the A/D integration time to achieve a longer pulse measurement. This can extend the measurement time for long integration to a maximum of 60S.

Note: When this feature is used, the current range is

set to 5A.

Long integration

Parameter Description

IntTime

 Integration time  The integration time can be set

manually or automatically by the operator. For manual settings, the integration time can be set to a maximum of 60 seconds. For a line frequency of 60Hz the minimum integration time is 850mS with a step resolution of 16.7mS. For a line frequency of 50Hz, the minimum integration time is 840mS with a step resolution of 20mS.

 When the integration time is set to Auto

Time, the system will automatically measure the time between two adjacent rising edges and an appropriate integration time is set for the peak and trough. If there are more than two pulses, the integration time must be set manually.

TrigEdge

 Trigger edge  Pulse edges are used to trigger long

integration measurement. Regardless of whether a rising or falling edge is used as a trigger, a pulse must furst be detected before measurement can start. Measurement can also start without an edge trigger. When Trig On Neither is selected, measurement starts as soon as the output is turned on.

PPH-1503 User Manual

BASIC OPERATION

Timeout

 Pulse timeout  When long integration measurement is

selected and the unit doesn’t detect a

pulse after a certain amount of time (pulse timeout time), the “No Pulse” message will be displayed on the LCD. This function is only applicable if rising or falling edge is selected as the edge trigger; the Trig On Neither trigger setting has no pulse timeout. The pulse timeout has a range of 1~63 seconds.

TrigLeve[4]

 Trigger level.  When the rising or falling edge trigger is

selected for long integration current measurement, a pulse must first be detected. The trigger level refers to minimum pulse level required for a pulse to be detected. For example if the trigger level is set to 2A, pulses that are

≤2A will be detected. Pulses <2A will be

ignored. The trigger level range is 0~5A. This setting only applies to long current integration measurements.

Function Description

When the test circuit is an active circuit, and the manifested voltage in the test circuit is greater than the output voltage of the power supply, the power supply will automatically disipate current from the external power supply. When this function is in the normal operating state, the power supply outputs the setting voltage, which is equivalent to a constant voltage load rather than constant current load.

The current disipation from the power supply output flows from the positive terminal out to the negative terminal. The amount of current sunk is not controlled from the power supply.

Connection

Connect the positive terminal of the external power supply to the positive terminal on the high-speed power supply. Connect the negative terminal of the external power supply to the negative terminal on the high-speed power supply.

Current Sink Function

Conditions

To protect the high-speed power supply when operating as a current sink, the following two conditions must be met:

1. Ensure that the voltage of the external power

supply is greater than the output of the highspeed power supply voltage by 0.3V~2.5V. The voltage difference depends on the high-speed power supply voltage output and the load conditions.

2. To ensure that the high-speed power supply

output voltage is within the range of 0~5V, the current draw cannot exceed 2A. For output voltgages between 5V~15V, the current draw must be reduced by 0.1A for each 1V increase over 5V. See the formula in the table below for the details.

Function Description

When the Relay control feature is turned on, it is synced to the current limit of the power suppy. The external relay control is divided into two different types, a limit relay and a trip relay.

The limit relay is used in conjuction with CC mode. When the constant current setting value is reached, the relay control signal will go high and will return back to the low level when the current level goes back below the constant current setting.

The trigger relay is used in conjuction with CC mode. When the constant current setting value is reached, the relay control signal will go high and the output is disabled. When the output goes back on and the current is less than the current setting value, the relay control signal will back to the low level.

Rear Panel Control Interface

The rear panel control interface has five terminals, +5V, IN(software upgrade), OUT (outputs the control signals) and GND (connected to the chasis ground or earth ground), respectively.

Wiring Method

A thin screwdriver or similar tool will need to be inserted into the release mechanism (highlighted in orange in the figure above) to open the terminals. Insert an exposed wire into the terminal and release the mechanism to lock the wire into place.

Command Syntax

The commands that are used with the PPH-1503 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

REMOTE CONTROL

is defined by a different root keyword. Each command consists of a root

keyword and one or more hierarchial 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 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).

Symbol Desription

SCPI commands have the following convential 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. Verical Bars

PPH-1503 User Manual

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

<brightness>, <brightness> must be use a numerical value instead such

as, :DISPlay:CONTrast 1

Parameter Types

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. Consectutive Integers

REMOTE CONTROL

Parameters that use consecutive integers, for example: For the

command :DISPlay:CONTrast <brightness>, <brightness> 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 {<current>|MINimum|MAXimum}, is used to set the current

value for the current operating channel. <current> 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|4|5} command can only use 0, 1, 2, 3, 4,

5. ASCII Strings

ASCII string parameters must use a combination of ASCII characters in a

string. For example: For the command :MODE <name>, <name> must

be an ASCII string.

Command Abbreviations

The syntax for SCPI commands contain 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:

Command Terminators

When sending a command to the function generator, the command must be terminated with a <new line> character. The IEEE-4888 EOI can also be used as a <new line> character. A command can also be terminated using a carriage return + <new line> 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.
