Swift Responses with Accurate Measurement
The PPH-1503/1503D are equipped with the excellent transient recovery time, which can, in less than 40us, recover the
output voltage to within 100mV of the previous voltage output when the current level changes from 10% to 100% of the
full scale. Furthermore, conventional power supplies do not have sufficient response speed to promptly respond to set
voltage value once the set voltage is changed. PPH-1503D has a rise time of 0.2ms (PPH-1503 : 0.15ms) and a fall time
of 0.3ms (PPH-1503 : 0.65ms), which are 100 times faster than that of conventional power supplies. Therefore, the PPH1503/1503D can provide DUT with a stable output voltage even when DUT is operating under large transient current
output. The internal high-speed sampling circuit design of the PPH-1503D, with the sample rate of 64K (PPH-1503:
60K), can conduct pulse current measurement without using a current probe and oscilloscope. The current read back
accuracy is 0.2% + 1mA (equals to 11mA) at 5mA range, and the read back resolution is 0.1mA that allow DUT to be
measured with a high accuracy level. Unlike battery, general power supplies, which do not have the characteristics of fast
transient recovery time, can not maintain a stable power supply for cellular phone, wireless device, and wearable device
which produce large transient pulse current load for hundreds of ms to dozens of ms when in use. PPH-1503D, different
from general power supplies, has the characteristics of fast transient recovery time. While simulating battery to output
pulse current, PPH-1503D can quickly compensate the voltage drop caused by pulse current. PPH-1503D's CH1 has the
built-in battery simulation function, which can define output impedance settings so as to accurately simulate battery's
impedance characteristics during battery discharge. Fast transient recovery time and built-in battery simulation function
together facilitate PPH-1503D to accurately simulate battery's real behavior pattern so as to conduct product tests.
PPH-1503D is not only suitable for simulating battery, charger and supplying power to DUT, but also ideal for simulating
an electronic load to conduct discharge tests with its sink current capability. The sink current function allows the PPH1503/1503D to simulate a voltage source with the sink current capability. Long integration current measurement can be
utilized to conduct average current measurement for periodical pulse current in a long period of time that is applied to
analyze power consumption for a period of time. One of the applications is to measure the average power consumption
of a cellular phone in use so as to conduct the internal RF module parameter analysis. The built-in sequence function of
PPH-1503D's CH1 provides users with 1000 steps to edit sequential outputs, including voltage, current and execution
time. The built-in DVM function of CH2 has a voltage range from 0 to +20VDC that saves users the cost of purchasing
an additional voltage meter.
PPH-1503/1503D are ideal power sources for production line, R&D laboratory, device inspection, maintenance center
or applications with the requirements of a fast and accurate power supply with DVM. PPH-1503/1503D support test
requirements of Profile1, Profile2 and Profile3 from USB Power Delivery(PD) constructed by USB-IF association.

PPH-1503/1503D provide 0.2%+1 A readback accuracy and
0.1 A resolution for high precision of current measurement.
For example, when portable device works in the sleep or
standby mode, the current is drawn at a low level. The low
current consumption under standby or sleep mode can be
measured accurately.
C.
FAST RESPONSE TO LOAD AND VOLTAGE CHANGES
PPH-1503
When DUT such as cellular phone switches to idling, receiving or
transmitting mode, the current drawn from power supply changes
over tenfold. The sudden current change will cause the supplied
voltage to drop as well. The conventional power supply is considered
a dull device since it will take several milliseconds for the dropped
voltage to return to the original level. PPH-1503/1503D are designed
to simulate battery response when a significant voltage drop occurs.
Recovery time of 40 s or less is guaranteed when the maximum
D.
Conventional Power Supply
voltage drop is within 100mV. Moreover, when users change
the voltage level and conventional power supply does not
have sufficient speed to reach the set level, PPH-1503/1503D
provides rise time of (PPH-1503 : 0.15ms/PPH-1503D : 0.2ms)
and fall time of (PPH-1503 : 0.65ms/PPH-1503D : 0.3ms),
which are hundreds times faster than that of the conventional
power supplies.
MEASUREMENTS FOR POWER CONSUMPTION ANALYSIS
Voltage and Current Waveforms of the Receiving Signals of a Cellular Phone
One particular requirement of power consumption for portable
wireless communications devices is Pulse Current. Portable devices
such as cellular phones must transmit and receive (detect) signal
periodically by drawing pulse current instead of constant current
from battery to ensure devices' sound connection in network. To
analyze the transient power consumption of a DUT, the peak of
short pulse current and average current measurements over a
E.
long period of time are crucial. PPH-1503/1503D provide
pulse current and long integration functions, the former can
measure the peak value of a pulse, the latter can measure the
average value of pulses. PPH-1503/1503D provide DUT with
pulse current measurement and analyzes the transient power
consumption to qualify the device for specified power
consumption requirements.
LONG INTEGRATION CURRENT MEASUREMENT
Long Integration Measurement for PPH-1503D
Long integration is an average current measurement of one or
more pulses. A pulse edge can be used to trigger the start of a
measurement. Measurements can be taken from pulse's positive
edge trigger or negative edge trigger. Users can also take
measurements from the beginning of power output. The long
integration time period must be a full period or integer multiples
of a complete period of the measured pulse current and can be
set to a maximum of 60 seconds. Long integration analyzes
products' overall power consumption at a certain period of time,
for instance, measuring the power consumed from beginning to
the end of a phone call for a cellular phone so as to analyze all
parameters of RF module.
F.
PULSE CURRENT MEASUREMENTS
Pulse Current Measurement for PPH-1503D
The Time Specified for the Measurement
PPH-1503/1503D DC power supply can perform current measurements
for pulsing loads. Its several built-in measurement modes include :
- High Measured Current-measure the peak current of the pulse train.
- Low Measured Current-measure the low current of the pulse train.
- Average Transmit Current-measure the average current of the
pulse train.
Pulse current measurement can measure transient current
consumption to provide the information for the allocation of
power supply system for products' preliminary design, i.e.
power supply circuits, battery selections for clients' product
analyses. Portable communications products, i.e. RF modules
and designs based upon blue tooth system can better use
pulse current measurement function.
The high, low, and average measurements of a pulse are illustrated
as above : To avoid false pulse detection, users can use a trigger
level of up to 5A(Ch1). All pulses, noise or other transients that are
less than set trigger level will be ignored. The manual integration
time range setting is 33 us to 833,333 us.

When connecting with an electric potential circuit and the output
voltage of the tested electric potential circuit is greater than that of
PPH-1503/PPH-1503D by approximately 0.3V to 2.5V, PPH-1503/
1503D will automatically convert its power supply role to the sink
current role acting as a load of voltage source. At this time, the
voltage setting of PPH-1503/1503D can be regarded as the CV
setting of an electronic load. A single PPH-1503/1503D can be
used to charge battery and to simulate battery's load to consume
power without extra instruments. It is ideal for tests on battery
and portable charger.

BUILT-IN DIGITAL VOLTMETER
DVM Input for PPH-1503D
The PPH-1503/1503D built-in Digital Volt-Meter (DVM) have
dedicated input terminal located on the front panel. With the DC
voltage measurement range from 0 to +20VDC, PPH-1503/1503D
not only provide power supply for DUT but also measure the
voltage on DUT. The read back accuracy reaches (0.05%+3mV)
and read back resolution is 1mV. Users are able to save the
cost of purchasing an extra voltage meter. Furthermore, DVM
measurements can be remotely controlled by SCPI commands
via a PC.

does not exceed 150mA.
Using an external power source to drive
the external relay. The voltage of the
source can not exceed 15V and the
current can not exceed 150mA.
Trip Relay
PPH-1503/1503D provide Limit relay and Trip relay modes and are
equipped with corresponding output ports, in which output signals
control external relay. Under Limit relay mode and the current limit is
reached, PPH-1503/1503D will switch from constant voltage to constant
current automatically. Under “Trip Relay” mode and the current limit
is reached, PPH-1503/1503D will turn output off. Furthermore, External
Relay control can be used if users simultaneously use other devices for
test system. When “Limit Relay” mode is selected and the current limit
is reached, External 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. When “Trip Relay” mode is selected
and the current limit 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, the
relay control signal will back to the low level. Users can use
relay control signal to control other devices for test system.
