Overcome Your Power Test Challenges
Accelerate test throughput with industry-leading specifications
Shaving seconds or even milliseconds off a test time can lead to significant savings for high- volume
manufacturers, making throughput gains a never-ending quest for test system designers. The APS is a
valuable tool for increasing throughput. It provides a number of industry-leading specifications and
innovative features that can help you achieve significant throughput gains in your testing. Some
• Industry-leading command processing time (<2 ms)
• Fast up and down programming speeds (up to 500 μs)
• Adjustable measurement times for optimum measurements in minimum time

• Accurately capture dynamic current profiles: APS has two current measurement ranges that allow it
to measure micro-amps to amps. The APS uses seamless ranging technology to transition from one
measurement range to the other without discontinuities in the output power or in measurement data

Reduce ATE development time and support costs with integrated features
Continuously source and sink current for power storage test applications
When operated as standalone units, APS power supplies can continuously sink up to 10% of their rated
output current for an indefinite time. With the addition of APS N7909A power dissipater units, APS power
supplies can continuously sink up to 100% of their rated output current. This means you can sink the
power supply’s full-rated output power for an indefinite time. Note that the two-quadrant sourcing and
sinking capability of the DC power supply allows for continuous transitions between sourcing and sinking
These capabilities make the APS an ideal solution for continuous source and sink testing needs in power

To complement the two-quadrant operation, all APS power supplies have built-in programmable output
resistance capability. This capability allows an APS power supply to simulate the internal resistance of
a battery
Smart triggering: Increase throughput, protect your DUT, and reduce
test complexity
条件：you would expect in a system power supply, but it goes well beyond with capabilities such as:
• Level triggering allows you to execute a trigger from five different APS measurement parameters:
The APS’s smart triggering system provides trigger capabilities never before seen in a power supply. The
APS’s smart triggering can accelerate your test throughput, better protect your DUT, and reduce the
complexity of your test system. The smart triggering system includes all the basic triggering functionality

non-volatile memory regardless of what the power supply is doing or how it is being used.
If you are testing expensive prototypes and a power-related problem damages or destroys your DUT, you
need to figure out what went wrong to ensure it does not happen again. The APS’s optional black box
recorder (BBR option) overcomes this test challenge by creating a power event record inside the power

Using instrumentation with built-in protection features provides a huge benefit when DUT protection is
required. Here’s why

Generate voltage and current transients
条件：DUT can stand up to these real-world transients, you must simulate worst-case power transient conditions
DUTs that are operated in rugged environments, such as automotive electronics and avionics, can often
experience transient behavior from the power source, such as voltage dropouts or surges. To ensure your

条件：A one-time event that steps the output voltage or current up or down in response to a triggered event.
Arbitrary waveforms: An arbitrary waveform generator (arb) allows you to generate complex user-
defined voltage or current waveforms of up to 65,535 data points.
List: A list can consist of up to 512 steps. Each step in the list can have a unique dwell time associated
with it, which specifies the time in seconds that the list will remain at that step before moving on to the
next step. Lists can also be trigger-paced, in which case the list advances one step for each trigger
条件：current transients, refer to the specifications section in this document or the APS user manual.
For a demonstration of the APS’s arb capability, an example “interrupt” pulse was generated with the
N7951A into a resistive load. The interrupt pulse goes from 20 V to 2 V for 10 ms and then returns to 20
V. The resulting interrupt pulse was captured (Figure 4), and its fall time was measured to be <
200 μs
(Figure
5). For more information on the APS’s output bandwidth and speed for generating voltage and

complexity to an ATE test system, both in hardware and software.
The APS power supplies can help you overcome this test challenge by providing built -in sequencing
capability across APS mainframes or with Keysight’s popular N6700 family of modular system power
supplies. Also, the APS power supplies provide adjustable slew rate control at turn- on or turn-off. These
built-in capabilities provide a clean, low-complexity way to properly power on or off your DUT during the

and the other supply will source only a fraction of the current and operate in CV mode. This condition can
highly degrade certain power supply performance specifications, such as transient response.
Add power flexibility to your test system by paralleling multiple APS supplies
The downside of paralleling power supplies together is you cannot get all the supplies to operate in the
desired constant voltage (CV) or constant current (CC) mode. For instance, when trying to operate in CV
mode with two parallel supplies, one will typically source the bulk of the current and operate in CC mode,
With the APS you do not have to worry about this since it has built-in paralleling capability that ensures
each supply equally shares the load current so they all remain in the desired mode, whether it is CV or
CC. Note that paralleling works whether the APS power supplies are sourcing or sinking current from
the DUT
条件：five APS power supplies (recommended), which provides a maximum power of 10 kW.
To take advantage of the APS paralleling capability, you need only a simple three- wire connection in the
rear of the supplies in the parallel configuration (see Figure
6). With this capability, you can parallel up to

The connections are located on the rear panel of both the N7909A and the supply, as shown in Figure 7.
The N7909A does not operate as a standalone instrument. It only works with an APS power supply.

APS black box recorder (option BBR)
Much like a flight data recorder, the black box recorder (BBR) runs continually in the background,
independent of what the power supply is doing. When the power supply is on, the BBR is recording power
events and storing measurements in non-volatile memory. The BBR can be set for either a
24-hour
record or a 10-day record period. In the
24-hour mode, measurements are made at a rate of 100 per
second, and in the
10-day mode, they are made at a rate of 10 per second. The BBR data can be
accessed via the free APS power assistant software (see Figure 8 on page
13 ). The BBR option works on
all APS N6900 and N7900 power supplies. It is a factory-installed option available only at the time of
条件：is needed for every APS power supply or N7909A dissipater that you would like to mount.

APS General Information
APS N6900 Series and N7900 Series power supply power
条件：nominal line voltages in the range of 100 VAC to 240 VAC. The frequency can be 50 Hz, 60 Hz, or 400
its maximum output power will be limited to 700 W. In this condition, if the power supply exceeds 700 W
of output power, the instrument turns off the output and sets the CP+ status bit.
Connect the power cord that was supplied with your unit to the AC mains connector on the rear of the
unit. Note that these cords are standard and are specially rated to handle the power needs of the APS
supply they are shipped with. The AC input on the back of your unit is a universal AC input. It accepts
Hz. AC mains rated below 180 VAC cannot supply enough current to power either the 1 kW or the
2 kW
N6900 and N7900 models to their full-rated output power. In such cases, when a
1 kW or 2 kW APS
power supply is connected to below 180 VAC AC mains, the power supply will still operate normally, but
APS power supply connectivity
All APS power supplies come standard with GPIB (IEEE-488), LAN (LXI-Core), and USB remote
programming interfaces. GPIB and LAN parameters can be set via the front panel. The APS is LXI Core
2011 compliant and includes a built-in Web interface. This means you can control the APS remotely using
