Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
WARNING
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating at a
high voltage relative to chassis ground.
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
WARNING cause damage to the equipment.
Only qualified personnel, who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC input power line ground is connected properly to the unit safety ground chassis.
Similarly, other AC power ground lines, including those to application and maintenance equipment, must
be grounded properly for both personnel safety and equipment protection.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure
that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact
with hazardous voltages is prevented.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses
and protective clothing during open cover checks to avoid personal injury by any sudden component
failure.

Asterion Series User Manual – 2U Models
California Instruments
1. Introduction
This instruction manual contains information on the installation, operation, and calibration of the
Asterion Series power source models with 1-phase/3-phase output in 2U chassis. The Asterion Series is
the latest generation of switched-mode power sources that provide precise output having high accuracy,
low distortion, and fast dynamic response. With extensive programmability and user interface, it offers a
rich feature set and functionality: AC and DC output capability, wide output frequency range, arbitrary
and harmonic waveform generation, sequencing of transient lists, digital power analyzer measurements,
real-time waveform display, and the capability to be configured in systems comprised of multi-phase and
parallel groups.
Figure 1-1. Asterion Series Front View, 2U Models
1.1 General Description
The Asterion Series power sources are available in 2U chassis at power levels of 1500 VA, 2250 VA, and
3000 VA. Two AC output voltage ranges are provided, 0-200 VAC/0-400 VAC, with a frequency range of
16 Hz-1000 Hz (with up to 5000 Hz as an option), two DC output ranges, 0-250 VDC/0-500 VDC, and a
combined AC+DC mode. A wide range of AC and DC loads could be powered, including reactive loads
(inductive and capacitive) running at full rated apparent power, and non-linear loads drawing current with
high crest factor, up to 7:1.
The output has an iX2TM constant-power characteristic that provides greater output current at reduced
output voltage: up to 2X at 50% of full-scale voltage. Wide-range AC input is accepted, including
100/115/230/240 VAC, 1-phase/3-phase, and 50/60/400 Hz input frequency. Power factor correction of
the AC input with low input current harmonics, producing PF of 0.98 in 1-phase input. Up to six 2U units
could be connected in parallel or in multi-phase groups, with outputs of up to 18 kVA.
Multiple remote digital communications interfaces are available: standard LAN (Ethernet), USB, and
RS-232C, or the optional IEEE-488 (GPIB) interface. The Asterion Virtual Panels program provides a
convenient graphical user interface, and the SCPI command set allows access to the full
programmability and functionality. Extensive remote analog and discrete digital control interfaces are
also provided for specialized control applications. The front panel display has capability for control,
programming, and measurements of the power source, and features a menu-based interface with
touch-screen data/command entry.
Waveform generation includes standard sine wave and square wave, and extensive programmability to
produce complex waveforms based on harmonics or arbitrary parameter value/time relationships. A
transient generator could combine sequences of voltage, frequency, and wave shape to simulate
real-world AC or DC disturbances, and automate a complex profile of power stimulus to the unit under
test.
The power analyzer utilizes DSP-based digitization of output parameters to implement measurement
functions spanning single parameter values (voltage/current/frequency), power characteristics
(true/apparent power, crest factor, power factor), and advanced computation using fast Fourier transform
(FFT) derivation of the harmonics and distortion contained in the voltage and current waveforms.
Real-time display of output waveforms is possible through the front panel display or the
Asterion Virtual Panels.

iX2TM Constant-Power Mode Output Characteristic
The iX2TM Constant-Power mode has an output characteristic where full rated output power is available
from 50% of full-scale output voltage to 100% of full-scale output voltage, as depicted in the graphs of
Figure 2-1 and Figure 2-2. The output current versus output voltage follows a constant-power relation
where the output current would be 200% of the full-scale value when the output voltage is 50% of
full-scale. The current ratings are also a function of output frequency, as shown in Figure 2-1 above
500 Hz for the AST 2253 and AST 3003 (1-Phase) models, and in Figure 2-2 above 1 kHz for the
AST 3003 (3-Phase) models.

3.2 Mechanical Installation
The Asterion Series power source is designed for rackmount and bench-top applications. It could be
used free standing on a bench top or rackmounted using optional mounting hardware. For bench-top
use, the ship kit contains the four bumper feet for installing to the bottom of the chassis using 8 mm long
M3 X 0.5 Philips pan-head screws and 3 mm washers. Rackmounting requires installing the optional
flange brackets with handles to the side of the chassis: using 6 mm long M5 X 0.7 Philips flat-head
screws to mount the brackets to the chassis, and # 6-32 Philips flat-head screws to mount the handles to
the brackets.
The unit is forced-air cooled with internal fans drawing air in from the front and sides, and exhausting at
the rear. The front and rear of the unit must be kept clear of obstruction and clearance must be
maintained to allow unimpeded airflow. The same consideration given to the side grilles will minimize
internal temperature rise. Special consideration must be made to overall air flow characteristics, and the
resultant internal heat rise, when a source is installed inside enclosed cabinets to avoid excessive
heating and over-temperature problems. The temperature of the ambient air at the air intake should not
exceed 40°C.
WARNING!
This unit is intended for installation in a protected environment. Exposure to conductive
contaminants or corrosive compounds/gases that could be ingested into the chassis
could result in internal damage. Install the power source in a temperature and humidity
controlled indoor area.
CAUTION!
The power source should be provided with proper ventilation. The front and rear of the
unit must be free of obstructions. To ensure proper airflow, a minimum 2" clearance from
the rear air outlet is required.
CAUTION!
No user serviceable parts are inside; service is only to be performed by qualified
personnel.

WARNING!
High voltage present at rear panel poses risk of electrical shock. The input and output
covers must be installed in bench top applications to maintain protection against
hazardous voltages. Do not remove protective covers on AC input or AC/DC output. Refer
installation and servicing to qualified personnel.
WARNING!
The input and output voltages at the rear panel of the unit are HAZARDOUS LIVE. When
rackmounting or panel-mounting the unit, suitable safeguards must be taken by the
installer to ensure that HAZARDOUS LIVE voltages are not operator accessible.
WARNING!
Capacitors in the power source might hold a hazardous electrical charge even if the power
source has been disconnected from the AC mains supply. Allow capacitors to discharge
to a safe voltage before touching exposed pins of mains supply connector.
WARNING!
A safety disconnect device for the AC mains input must be installed so that it is readily
accessible to the operator.
WARNING!
A properly sized input overcurrent protection device must be installed at the AC mains
input. It could be either a circuit breaker or fuse having a rating of 25% over the maximum
AC input line currents listed in the specifications of Section 2.1.3.
WARNING!
To prevent an electrical shock hazard, a safety ground wire must be connected from the
safety-ground stud on the rear panel to the AC mains earth protection-ground

3.6 AC Input Connection
The Asterion Series power source is designed to operate from 1-phase or 3-phase input power, having
2-wire/3-wire plus ground, with nominal AC input voltage of 100/115/230/240 VAC, and 50/60/400 Hz
input frequency. The AC input voltage range is automatically selected by the unit at power-up; no user
setup is required. Power factor correction (PFC) provides high power factor, minimizing the required
input apparent power and current harmonic distortion. Refer to the specifications of Section 2.1.3 for AC
input current requirements, and derating of output power as a function of AC input voltage.
3.6.1
AC Input Overcurrent Protection
The Asterion Series power source has fuses at the AC input for fault protection. These fuses are internal
to the chassis, and are not user accessible. They provide fault isolation in case a failure occurs of
internal components or wiring. A suitable overcurrent protection device must be provided externally,
within the system installation, to protect the external wiring and interconnects.
3.6.2
AC Input Safety Disconnect Device
The Asterion Series power source front panel POWER switch does not disconnect the AC input line from
the unit. Ensure that an appropriately rated safety disconnect device is incorporated in the installation
that will provide isolation from the AC input when the device is opened. The device could be a switch or
circuit breaker, and must be located close to the unit, within reach of the operator, and clearly labeled as
the disconnection device.
3.6.3
AC Input Connector
The AC input connector, AC INPUT, is located on the rear panel, along with the safety-ground stud.
Figure 3-6 shows the rear panel view of the connector and stud. Table 3-1 shows the functions and

3.9 Remote Sense
Output voltage sensing is user-selectable to be either local sense or remote sense. Sensing provides the
signal for measurement of the output voltage, and determines the physical point where the output
voltage is precisely regulated. Local sense is at the rear panel output connector, while remote sense is at
the load, through a cable connection from the rear panel remote sense connector. An internal relay is
used to select which sense signal is used by the controller.
Remote sensing is used to compensate for the voltage drop that occurs across the wires connecting the
load to the output of the power source. A separate pair of wires is routed to measure the voltage at the
terminals of the load where precise regulation of the output voltage is desired. The remote sense leads
are connected at the Remote Sense connector on the rear panel; refer Figure 3-7. Connect the
terminals, Sense Phase-A/B/C, to the points at the load that are connected to the Output Phase-A/B/C
LINE terminals, and the terminal, Sense RTN, to the point at the load that is connected to Output RTN
terminal.
Special care is required in routing the sensing leads to prevent noise pickup or coupling to the power
leads; refer to Section 3.10. The sense leads should be a twisted-pair of at least AWG #22 wire, and
may require shielding in high noise environments. If a shield is used, connect it to the functional-ground
terminal at the AC/DC Output connector location.
If the remote sense leads are not connected, but remote sense has been selected, the AC source will
continue to operate but the voltage at the load will no longer be precisely regulated. An internal circuit
exists within the unit that provides redundant voltage sensing from the output terminals, in case the
remote sense leads are not connected. However, this condition does not have voltage calibration, and
since the voltage is now measured at the output terminals, the voltage drop of the load wiring would no
longer be compensated.
Two conditions related to remote sensing are treated as faults and result in shutdown of the output:
short-circuiting of the remote sense terminals or connecting the remote sense leads in reverse polarity.
When the fault condition is detected, shutdown will result with the output voltage being programmed to
zero and the output isolation relays being opened.
3.10
Noise and Impedance Effects
To minimize noise pickup or radiation from load circuits, load wires and remote sense wires should be
twisted-pair and have minimum lead length. Shielding of the sense leads may be necessary in high noise
environments. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to
reduce coupling between them, which could impact the stability of the output amplifier. Twisting the load
wires provides an additional benefit in reducing the parasitic inductance of the cable. This improves the
dynamic response characteristics at the load by maintaining low source impedance at high frequencies.
If connectors are utilized for the power and sense leads, consideration of routing is necessary to
minimize coupling between the leads. Ensure that the connector terminals for the sense leads are in
adjacent contact locations, and minimize the physical loop area of the untwisted portions.

When determining the optimum cable specification for your power applications, the same engineering
rules apply whether at the input or output of an electrical device. Therefore, this guide applies equally to
the input cable and output cable for this power source and application loads.
Power cables must be able to safely carry maximum load current without overheating or causing
insulation degradation. It is important to power source performance to minimize IR (voltage drop) loss
within the cable. These losses have a direct effect on the quality of power delivered to and from the
power source and corresponding loads.
When specifying wire gauge, consider derating due to operating temperature at the wire location. Wire
gauge current capability and insulation performance drops with the increased temperature developed
within a cable bundle and with increased environmental temperature. Therefore, short cables with
derating of gauge size and insulation properties are recommended for power source applications.
Be careful when using published commercial utility wiring codes. These codes are designed for the
internal wiring of homes and buildings and accommodate the safety factors of wiring loss, heat,
breakdown insulation, aging, etc. However, these codes consider that up to 5% voltage drop is
acceptable. Such a loss directly detracts from the performance specifications of this power source. Also,
consider how the wiring codes apply to bundles of wire within a cable arrangement.
In high performance applications requiring high inrush/ transient currents, additional consideration is
required. The cable wire gauge must accommodate peak currents developed at peak voltages, which
might be up to five times the RMS current values. An underrated wire gauge adds losses, which alter the
inrush characteristics of the application and thus the expected performance.
Table 3-8 presents wire resistance and resulting cable voltage drop at maximum rated current, with the
wire at 20°C. Copper wire has a temperature coefficient of α = 0.00393Ω/°C at t1 = 20°C, so that at an
elevated temperature, t2, the resistance would be R2 = R1 (1 + α (t2 - t1)).
The output power cables must be large enough to prevent the line voltage drop (total of both output
wires) between the power source and the load from exceeding the remote sense capability as presented
in the specification section. Calculate the voltage drop using the following formula:
Voltage Drop = 2 × distance-in-feet × cable-resistance-per-foot × current

3.12.2 Remote Inhibit Signal
The Remote Inhibit signal, /INHIBIT_ISO (Pin-12), can be used to turn the output on/off and close/open
the output relay of the power source. When set to the off state, this input overrides the output state
programmed through the front panel or the remote digital interface.
The default logic-level for Remote Inhibit is a logic-low or contact closure between /INHIBIT_ISO (Pin-12)
and ISO_COM (Pin-9). This will cause the output voltage to be programmed to zero volts and the output
relays to open. This logic-level could also be selected with the SCPI command, OUTPUT:RI:LEVEL LOW.
Alternatively, the logic-level could be changed by the user to logic-high using the remote digital interface
SCPI command, OUTPUT:RI:LEVEL HIGH. A logic-high or open-circuit between /INHIBIT_ISO (Pin-12) and
ISO_COM (Pin-9) will cause the output voltage to be programmed to zero volts and the output relays to
open.
The mode of operation of the Remote Inhibit can be changed using the remote digital interface SCPI
command, OUTP:RI:MODE <mode>. The following modes can be selected:
LATC(hing)
A TTL logic-low (or user-selected logic-high) at the Remote Inhibit input latches
the output in the protection shutdown state; this state could only be cleared by
the remote digital interface SCPI command, OUTPut:PROTection:CLEar.
The output state follows the state of the Remote Inhibit input. A TTL logic-low (or
user-selectable logic-high) at the Remote Inhibit input turns the output off; a TTL
logic-high (or user-selectable logic-low) turns the output on.
The power source ignores the Remote Inhibit input.
LIVE
OFF
The Remote Inhibit output mode state is saved at power-down. The factory default state is LIVE. For
additional information on programming the Remote Inhibit function, refer to the Asterion Programming
Manual P/N M330100-01 distributed on the CD, CIC496.

Multiple Chassis System Configurations
The Asterion Series power source has the capability to be configured in multi-chassis groups with
multiple-phase outputs using the optional Clock/Lock signal interface. The sources are individually
programmed for output voltage/current, while the Clock/Lock interface ensures frequency and phase
synchronization between units.
The power source could also be configured in parallel, multiple-chassis groups to extend the total output
power. The outputs of the individual units must be connected in parallel, and a Master/Auxiliary System
interface cable must interconnect them. The control interface of the units is automatically configured
when the Master/Auxiliary System interface cable is connected, so no setting changes by the user are
required.
3.13.1 Multi-Phase System
The connections to set up a multi-phase group of units require that the output lines, PHASE-A,
PHASE-B, PHASE-C and RTN, are connected independently from each output of a unit to the load. If the
remote sense is used, each unit must have it connected to the phase of the load at the point where
precise regulation of the output voltage is desired.
The units must have the Clock/Lock options installed, with the Master unit having the LKM option and the
Auxiliary units having the LKS option. The Clock/Lock connectors of the Master unit provide output
signals: CLOCK to set the frequency, and LOCK to set the phase. The Clock/Lock connectors of the
Auxiliary units are inputs to accept the control signals from the Master unit. The Clock and Lock
interfaces are signal buses, so the Clock connectors of all units must be connected, and the Lock
connectors must be connected together. Programming, readback, and control are done through the
individual units. Also, the Auxiliary units must have their phase programmed in reference to the Master
unit.
The clock source and configuration must be set for multi-phase operation through the remote digital
interface using SCPI commands or the front panel display. Set up through the front panel is as follows:
1. In the CONFIGURATION, PONS CLOCK CONFIG display menu, the Master unit must have the
configuration set to Master (the AC input must be cycled off/on for a change in a PONS setting to
take effect); refer to Section 4.5.5;
2. In the CONFIGURATION, PONS CLOCK CONFIG display menu, the Auxiliary units must have
the configuration set to Auxiliary (the AC input must be cycled off/on for a change in a PONS
setting to take effect); refer to Section 4.5.5;
3. In the CONFIGURATION, CLOCK MODE display menu, the Auxiliary units must have the clock
source set to External; refer to Section 4.5.5.
3.13.2 Parallel System
The connections to set up a parallel group of units require that the output lines PHASE-A, PHASE-B,
PHASE-C and RTN are connected together from each unit to an external terminal block. If the remote
sense is used, only the Master unit has it connected to the load at the point where precise regulation of
the output voltage is desired; the Auxiliary units do not have remote sense connected. The
Master/Auxiliary System Interface cable is connected from the Master unit connector, MASTER, to the
Auxiliary unit connector, AUXILIARY. Additional Auxiliary units are connected from the Master connector
of the last unit in the signal chain to the Auxiliary connector of following unit.
2U units of either 1500 W or 3000W rating could be connected in any combination to form a parallel
group. Units with a 2250 W rating must be paralleled only to units with the same rating. All programming,
readback, and control are done through the Master unit. The Master/Auxiliary interface is automatically
configured so that the current reported by the Master unit is the sum of all units within the group. The
M330000-02, REV-B

California Instruments
displays of the Auxiliary units are disabled, and show the message, “SOURCE IN AUXILIARY MODE No
access to the user”.
When the parallel group system is powered up, the order of powering the Auxiliary sources and the
Master source is not important. After the system is powered up, if an Auxiliary power source is powered
down there will be an error message displayed on the Master source, “Aux Down ensure all are powered
up”. If power is reapplied to the Auxiliary source, the message will disappear and normal operation could
resume. If the Master/Auxiliary System Interface cable is removed from the Auxiliary source while the
source is powered down, the error message will disappear, but the Master source will not have the
correct configuration. The Master source must have its AC input power toggled, Off to On, for the correct
configuration to be established.

4.4 Output Power Characteristic
The iX2TM Constant-Power output characteristic of the Asterion power source has a power limit that is
present in each of the two output voltage ranges (low-range and high-range) for AC and DC outputs. Full
rated output power is available from 100% of full-scale output voltage down to 50% of full-scale output
voltage; refer to Figure 4-4 for the relation between the voltage and current follows a constant-power
curve with the limit being the rated power of the unit: The output current increases to 200% of full-scale
output current as output voltage is reduced to 50% of full-scale output voltage. Accordingly, the power
source will automatically adjust the allowed maximum value of the programmed output current when the
output voltage is within 50% and 100% of full-scale to ensure that the power limit is not exceeded. Refer
to graphs for current rating as a function of output voltage and frequency in Figure 2-1 and Figure 2-2.

The DASHBOARD screen menu provides the capability for output parameter entry that has real-time,
immediate effect on the output. This allows manual adjustment of the output parameters where tuning of
a value is desired. Enabling this function requires clicking on a parameter selection-field box with the
encoder switch to select the parameter and display its selection-field highlighted and with a value entry
window (refer to Figure 4-14). The rotary encoder could then be used to continuously adjust the
parameter value, up and down, as it is rotated. The value change takes immediate effect at the output.

PHASE
California Instruments
Programs the phase angle of the output voltage in a standalone unit
operating in 1-Phase configuration; the phase angle would be with
respect to the external SYNC signal. In an Auxiliary unit (with
LKS option) of a multi-phase group, the phase angle would be with
respect to Phase-A, while Phase-A would be the reference at 0°. If
the clock source is selected to be internal, this parameter has no
effect. The default is zero.
In a 3-Phase configuration, programs the Phase-B and Phase-C with
respect to the Phase-A reference.
DC OFFSET
Programs the DC offset value, V(DC), when in the (AC+DC)-mode;
entries with positive and negative polarity are allowed. The AC
component of the output voltage is set separately using the
VOLTAGE selection-field (above) or through the Dashboard screen.
In AC-mode and DC-mode, this function is not available, and the
function is listed as “N/A”. The default is zero.
VOLTAGE RANGE
Selects the 200 VAC or 400 VAC range for AC-mode and
(AC+DC)-mode, and 250 VDC or 500 VDC range for DC-mode
operation. The output must be turned off for a change in range to be
executed. The default is low-range, 200 VAC.

VOLTAGE MODE
Selects the mode of operation of output voltage: either AC only, DC
only, or AC with a DC offset, AC+DC. This selection also determines
the available output voltage ranges: 200/400 V(RMS) in AC and
AC+DC modes, and 250/500 VDC in DC mode. The output must be
turned off to change this setting. The default is AC.
WAVEFORM
Selects the waveform for the output voltage: either standard
waveforms for sine wave, square wave, or clipped-sine wave; or,
user-defined waveforms. The default is sine wave.
The standard waveforms are always available, and do not consume
any of the user-defined waveform memory registers; they are always
displayed in the waveform list. The clipped-sine waveform has a
waveform where the peak amplitude of the positive and negative
alternation is clipped (flattened appearance). The level of clipping is
dependent on the amount of harmonic distortion present in the output
waveform. An additional programmable parameter, CLIP % THD, is
available for setting the percentage of total harmonic distortion
(THD); the range is 0-43%.
The user-defined waveforms could be selected from up to fifty
waveforms in one of four groups (group 0-3, totaling 200 waveforms)
that are active. The waveform group that is active at power-on of the
unit could be selected with the SCPI command,
PONSetup:WGRoup <n>, through the digital interface. For
information on generating user-defined waveforms and their
selection, refer to the Asterion Virtual Panels or the Asterion Series

REGULATION
California Instruments
Selects options for regulation of the output voltage: whether ALC is
enabled, and what control action will be performed when the load
current reaches the current setpoint. The defaults are CV/CL, with
Delay of 0.2 seconds and ALC on.
Constant-Voltage/Constant-Current (CV/CC): CV/CC mode will
regulate the output voltage to the set value until the load current
reaches the current setpoint; after the Delay interval, if the current
exceeds the setpoint, the output current will be controlled to equal
the setpoint. Regulation of the load current is accomplished by
reducing the output voltage as needed to satisfy the load. As such,
the voltage could be reduced from the set value down to zero,
depending on the load requirement. This mode is useful for starting
up motor or capacitor loads that may require a high inrush current.
In constant-voltage mode of operation, the waveform and
instantaneous amplitude of the output voltage is regulated to equal
the programmed values; if Volt ALC is enabled, the RMS value is
also precisely regulated. In constant-current mode of operation, the
RMS value of the output current is regulated to equal the
programmed value. However, this is accomplished by controlling the
voltage amplitude and waveform, and not directly the current;
therefore, the current instantaneous amplitude and waveform and
dependent on load characteristics.
Constant-Voltage/Current-Limit (CV/CL): CV/CL mode will
regulate the output voltage to the set value until the load current
reaches the current setpoint; after the Delay interval, if the
current equals or exceeds the setpoint, a fault condition will be
generated, and the output voltage will be programmed to zero
and the isolation relay opened. This effectively turns off the AC
source output in case of an overload condition, after the userprogrammable trip time-delay.
Delay: Sets the time duration that the output current could
equal or exceed the current setpoint before control action is
taken. After the delay, if CV/CC mode is selected, the output
current will be regulated to its setpoint; if CV/CL mode is
selected, an overcurrent fault condition will be generated and
the output will be turned off. The Delay is programmable from
0.1-5 seconds.
Volt ALC: Volt ALC selects whether the automatic loop control,
ALC, is enabled. ALC provides improved output regulation and
accuracy by regulating the RMS value of the output voltage
through action of a digital regulator that measures the output
voltage and controls it to equal the setpoint.
M330000-02, REV-B
75
Asterion Series User Manual – 2U Models
California Instruments
ON: ALC is enabled; regulation is accomplished through the
RMS digital regulator; if the RMS digital regulator exceeds its
control capability and could not maintain regulation, the output
will be shut down and a fault condition will be generated with the
output turned off and the voltage programmed to zero;
REG: ALC is enabled; regulation is accomplished through the
RMS digital regulator; if the RMS digital regulator exceeds its
control capability and could not maintain regulation, the output
will remain on, but the voltage will deviate from the setpoint, and
a fault condition will not be generated;
OFF: ALC disabled; regulation is accomplished without use of
the RMS digital regulator, and shutdown that is dependent on
loss of regulation will not occur.

MEASUREMENTS Screen Top-Level Menus
The Asterion Series power source uses a DSP-based data acquisition system to provide extensive
information regarding the output parameters. This data acquisition system digitizes the voltage and
current waveforms and calculates parameter values from the data. The result of these calculations is
displayed in a series of measurement data screens. The actual digitized waveforms can also be
displayed by selecting the Trace Capture screen. The MEASUREMENTS screen top-level menu is used
to display the results of output parameter measurements, harmonics analysis, and output waveforms.
The top-level menus of the MEASUREMENTS screens are shown in Figure 4-17. They can be reached

SINGLE: Single-shot acquisition; in this mode, the acquisition is
triggered once each time the START field is selected. The
selected trigger source is used to determine the trigger point.
Once the acquisition has been triggered, the data are displayed
and do not change until the next acquisition is triggered. This
mode is most appropriate for single-shot events, such as startup
currents.
CONTINUE: Continuous acquisition; in this mode, acquisitions
occur repeatedly and the data is updated on screen after each
trigger occurrence. This provides a continuous update of the
data, and is most appropriate for repetitive signals.
SOURCE
HARMONICS menu: Selects the event that will trigger a
measurement acquisition, as follows;
IMMEDIATE: Causes the acquisition to trigger immediately
when the START field is selected. This is an asynchronous
trigger event. The acquisition will always be triggered in this
mode and data is available immediately.
PHASE: Causes the acquisition to trigger on the occurrence of
zero phase angle of the output voltage. When started, the
acquisition holds until the zero phase angle occurs, before
triggering the acquisition. This mode allows exact positioning of
the acquisition data window with respect to the voltage
waveform.
DELAY

HARMONICS menu: Selects the time delay to position the
trigger point relative to the acquisition window. A negative value
will provide pre-trigger information on data leading up to the
trigger event. The pre-trigger delay cannot exceed the length of
the acquisition buffer; see Section 6.3.3 for details. A positive
trigger delay positions the data window after the trigger event.
Positive trigger delays can exceed the length of the acquisition
buffer in which case the trigger event itself will not be in the
buffer any more. The maximum value of the trigger delay is
1000 ms. The default trigger delay value is 0.0 ms which puts
the trigger event at the beginning of the acquisition window.

The Asterion Series power source provides the capability of generating custom waveforms through
programming the output in a sequence of steps in a list of transients. The steps could be comprised of
combinations of changes in voltage, frequency, phase angle, waveform, and duration. The list could be
created, run and stored through either the front panel, or the remote digital interface using the Asterion
Virtual Panels program or SCPI commands. A library of lists could be produced and stored in memory of
the power source for quick recall and utilization through use of SCPI commands or the Asterion Virtual
Panels; refer to the Asterion Series Programming Manual P/N M330100-01 distributed on the CD,

default value is zero, which means the programmed list runs only
once. The range for this field is from 0 through 99999. This
repeatable function should not be confused with the REPEAT
function available for individual events. The event-specific repeat
value will cause only that event to be repeated, not the entire list.
Start
Starts a transient execution. The output relay must be closed or an
error message will appear, and the transient will not start.
Abort
Once the START command has been set, the START
selection-button will change to an ABORT button, which could be

capacitive loads. Though stable with its normal feedback controller
compensation, additional stability margin could be achieved for
unusual loads by turning on XLOAD. This significantly improves the
transient response of the amplifier, but it should only be used for
reactive loads, and with programmed frequencies of less than
1000 Hz.

5. Waveform Management
The Asterion Series power source incorporates an arbitrary waveform generator that allows the user to
create custom waveforms (up to 50) and download them into the memory of the unit. In addition, three
standard waveforms are always available: sine wave, square wave, and clipped-sine wave. The full
capability of waveform management could be programmed through the remote digital interface using the
Asterion Virtual Panels or SCPI commands; refer to the Asterion Series Programming Manual
P/N M330100-01 distributed on the CD, CIC496.
5.1 Standard Waveforms
For many AC applications, the sine wave is the prevalent waveform that is used. Therefore, it is one of
the standard waveforms provided in the power source, and is the default waveform at power-on. In
addition to the sine wave, two more standard waveforms are available, square wave and clipped-sine
wave.
The square wave provides fast rise and fall times, with high harmonic content. Due to the power stage
amplifier bandwidth limitations, the frequency content of the standard square wave is restricted to be
within the capabilities of the amplifier. As the fundamental frequency is increased, the relative
contribution of higher harmonics is reduced.
The clipped-sine wave may be used to simulate voltage distortion levels to the unit under test. The total
harmonic distortion level may be programmed in percent using the CLIP % THD field of the
WAVEFORMS menu of the OUTPUT PROGRAM screen; refer to Section 4.5.2. Changing the distortion
level of the waveform through the display menu forces the power source to regenerate the data points of
the clipped-sine wave, and reload the waveform register with the newly requested data; this process
requires the output to be programmed to zero. To avoid interrupting the output voltage to the unit under
test, SCPI commands could be used through the digital interface to select a different waveform such as
the standard sine wave first, change the CLIP LEVEL, and then change the waveform back to the
clipped-sine wave.
5.2 Creating Custom Waveforms
The Asterion Series power source provides a library of four waveform groups (numbered 0 through 3),
each containing 50 custom-defined waveforms for a total of 200 waveforms, in addition to the three
standard waveforms. Of these four groups, only one could be active at a time. With front panel control,
only the waveform group that was present at power-on could be accessed. The available waveforms
could be selected through the WAVEFORMS menu of the OUTPUT PROGRAM screen; refer to
Section 4.5.2.
Custom waveforms cannot be created or deleted from the front panel of the power source. Instead, this
must be accomplished through the remote digital interface. The standard waveforms permanently reside
in memory, and could not be deleted. A Windows-based graphical user interface program, Virtual
Panels, is included with the power source that allows waveforms to be created and downloaded easily.
Virtual Panels allows waveforms to be created by specifying harmonic amplitudes and phase angles with
respect to the fundamental. It also offers an arbitrary waveform data entry mode that allows individual
data points to be specified. For detailed information on creating waveforms, refer to the Asterion
Programming Manual P/N M330100-01 distributed on the CD, CIC496.

Viewing Custom Waveforms on the Display
Information on user-defined, custom waveforms could be viewed on the display using the HARMONICS
menu of the OUTPUT PROGRAM screen; refer to Section 4.5.2. The harmonics could be displayed
either in a tabular form or a bar graph. Refer to Figure 5-1 for an example of the information on the
waveform that could be derived from the display. After loading a waveform, and programming the output
with it, the TRACE CAPTURE screen of the MEASUREMENTS menu could be used to view it in
real-time; refer to Section 4.5.3,
TABLE Sub-Menu
BAR Sub-Menu
Figure 5-1. HARMONICS Screen, Waveform Information
5.3 RMS Amplitude Restrictions
The maximum RMS value that could be programmed within a voltage range is dependent on the crest
factor of the output voltage waveform due to constraints of the power stage amplifier on producing the
peak voltage. The voltage range limit is based on a sine wave with a crest factor of 1.414: for example, in
the High-Range, the full-scale AC sine wave voltage of 400 V(RMS) has a peak voltage of 566 V(PK),
and that is the maximum peak voltage that could be produced for any other type of waveform. Therefore,
if a custom waveform is used and the crest factor is greater than 1.414, the maximum programmable
RMS voltage would be less than the maximum range value in order to stay within the peak voltage limit.
The power source automatically limits the maximum allowable programmed RMS voltage of any custom
waveform by calculating the crest factor of the selected waveform to ensure that the peak output voltage
capability is not exceeded, and controlling the RMS limit accordingly. Therefore, each custom waveform
might have a different maximum RMS value. The power source controller will prevent the user from
programming the RMS voltage above this limit. If a value is entered above this value, a “Voltage peak
error” message is generated.
If the power source is controlled through the remote digital interface, the SCPI query command,
:VOLT? MAX, could be used to determine the maximum allowable RMS voltage for the selected
waveform. The query returned value could be used as part of a program to preclude range errors.
118
M330000-02, REV-B
Asterion Series User Manual – 2U Models
California Instruments
5.4 Frequency Response Restrictions
The user could create a waveform that contains any number of harmonic frequencies of the fundamental.
However, the power source has a finite signal bandwidth and would attenuate frequency components of
the signal that exceed that bandwidth. To limit the high frequency components of the output signal, the
power source controller automatically applies a band-pass filter to all custom waveforms as they are
downloaded. The power source controller implements the following process for user-defined waveforms:
Each downloaded waveform will have a computed frequency limit that is less than or equal to the
maximum frequency limit of the power source. The frequency limit is a function of the harmonic content
of the waveform and is derived from the follow relation:
Fharmonic ≤ (Vfull-scale × Fmaximum) / (Vharmonic-amplitude × harmonic-number),
where, Fharmonic = harmonic frequency,
Vfull-scale = the full-scale rated voltage,
Fmaximum = the full-scale fundamental frequency,
Vharmonic-amplitude = the amplitude of the harmonic,
harmonic-number = the multiple of the full-scale fundamental frequency.
The limits that are set assume a program of full-scale output voltage. There are no accommodations for
voltage settings are made below the full-scale value. Waveform selection and frequency programming
will be subject to the limit. If the Fharmonic parameter is above the minimum limit value, the waveform will
be rejected at time of download, the entry label will be deleted from the waveform library, and an error
message will be generated.
If the power source is controlled through the remote digital interface, the SCPI query command,
:FREQ? MAX, could be used to determine the maximum allowable fundamental frequency for the
selected waveform. The value returned for the query could be used as part of a program to preclude
range errors.
5.5 Transient List Waveforms
Waveforms can be selected as part of a transient list. Each setup menu of a transient type has a
FUNCTION field that allows selection of any of the standard or user-defined custom waveforms available
in the active waveform group (one of the four, 0-3). The active group is the one loaded at power-on, or
selected by SCPI commands through the remote digital interface. For more details on selecting output
waveforms within transient lists refer to the Section 4.5.4.

6. Standard Measurements
The Asterion Series power source is continuously sampling the instantaneous output voltage and current
and storing the data in a buffer that holds 4096 voltage and current data points (frame). The data is used
to calculate the values of the parametric measurements, with two cycles of measurement required to
derive an RMS value. The voltage and current are sampled at two rates, 93.75 ksps or 31.25 ksps,
depending on output frequency. At ≥ 48 Hz, the sample rate is 93.75 ksps, giving a derivation time of
43.69 ms per frame. There is hysteresis of 4 Hz in switching to the lower sample rate, so at ≤ 44 Hz, the
sample rate is reduced to 31.25 ksps, and the time required per frame is 131 ms.
Measurement of output parameters is available in either the MEASUREMENTS screen (refer to
Section 4.5.3) or the DASHBOARD screen (refer to Section 4.5.1). The MEASUREMENTS screen
allows only for the display of measurements, and provides either a group display of parameters, or a
dedicated screen for each parameter that could be selected when a single parameter is of concern. The
DASHBOARD screen provides display of voltage, current, and frequency, as well as the ability to set
their values. The full extent of the measurements capability could be accessed through the remote digital
interface using SCPI commands or the Asterion Virtual Panels; refer to the Asterion Series Programming
Manual P/N M330100-01 distributed on the CD, CIC496.

Accuracy Considerations
When using the power source for measurement purposes, always consider the accuracy specifications
when interpreting results. Measurement inaccuracies become more pronounced as the signal being
measured is at the low end of the measurement range. This is particularly relevant for low current
measurements. The Asterion Series power source develops high levels of output power, and,
accordingly, is optimized for providing and measuring high load currents. When supplying low power
loads, measurement inaccuracies on RMS and peak current values will also affect other parameters that
are derived from those measurements, such as power, power factor and crest factor.
The measurement system of the power source uses a data acquisition system with a 47 kHz bandwidth.
This means that high frequency components of the measured signal are filtered out. Any contribution to
the RMS value of voltage and current components above the filter cutoff frequency would not be
reflected in the measurements. Accordingly, voltage and current measurements of waveforms with
significant harmonic content at high frequencies would incur additional error.
6.2 Advanced Measurements
The Asterion Series power source offers advanced power analyzer measurement capabilities through
DSP-based digitization of the output voltage and current waveforms. These functions may be accessed
through the menus of the MEASUREMENTS screen. The full capability of advanced measurements
could be accessed through the remote digital interface using the Asterion Virtual Panels or SCPI
commands; refer to the Asterion Series Programming Manual P/N M330100-01 distributed on the CD,
CIC496.
6.2.1
Harmonic Analysis
The power source analyzer performs a fast Fourier transform (FFT) on both voltage and current. The
resulting frequency spectrum (DC through 49th harmonic) can be displayed on the LCD display in a
tabular as well as a graphical format.
6.2.2
Acquiring FFT data
To perform an FFT analysis on the output of the power source using the front panel display, proceed as
follows:
1. Navigate to the HARMONICS menu of the MEASUREMENTS screen; refer to Figure 6-1.

4. Scroll to the DATA field and select ABSOLUTE or RELATIVE. The ABSOLUTE display
format will show all harmonic components in volts or amps. The RELATIVE display format
will use the fundamental as a 100% reference and display all harmonics as a percentage of
the fundamental. Phase angles are always shown with respect to the fundamental
frequency.
5. Tap the MODE field and select SINGLE or CONTINUE. The SINGLE mode will acquire the
data once and show the result, while the CONTINUE mode will update the data
continuously.

7. Tap Phase-A, Phase-B, or Phase-C button to select which output phase would be analyzed.
8. Tap the START field to start the analysis. The display mode that was selected will be
opened and the results displayed. If the trigger mode, CONTINUE, was selected, the data
will be continually updated.
9. Returning to the HARMONICS menu could be done by tapping the UP arrow button. To
display the data in a different format, the selections are changed as desired, and a new
acquisition started by tapping the START field.
6.2.3
Analyzing FFT Data
The FFT results could be displayed for the entire data set using either the tabular or graphical formats.
For tabular display, the harmonics are presented in five groups with ten harmonics per group. The LEFT
and RIGHT arrow buttons could be used to scroll through the data vertically; refer to Figure 6-2.
Figure 6-2. FFT data in Tabular Format
FFT data displayed in bar chart format shows the same data in a graphical format; refer to Figure 6-3.
While the amplitude information is shown graphically, phase data is only displayed in numeric format at
the right-side of the display. The display could show up to 25 harmonic components at a time. The
triangle at the bottom of the display shows the currently selected component for which numeric data is
shown on the right-side. This data includes the harmonic number (DC through 50), the harmonic
frequency, the absolute or relative amplitude (depending on selection in DATA field), and the phase
angle with respect to the fundamental. The rotary encoder could be used to scroll through the displayed
harmonics horizontally, or the touch-screen could be used to directly select an individual harmonic.

6.3 Triggering Measurements
Both FFT results and waveform acquisitions might have to be positioned at a specific instant in time. To
allow the data acquisition to coincide with user specified events, the measurement system can be
triggered in different ways. Trigger modes are available from both the digital interface and the front
panel. Refer to the Asterion Series Programming Manual P/N M330100-01 distributed on the CD,
CIC496, for details on this mode of operation.
6.3.1
Trigger Mode
Trigger mode could be selected from the front panel using the MODE field in the HARMONICS menu of
the MEASUREMENTS screen; refer to Figure 6-4.
The following trigger modes are available in the HARMONICS menu:
6.3.2
Single (SINGLE)
This mode causes the acquisition system to be armed only once after
the initial START. The power source waits until a trigger event
occurs, after which data is acquired; when acquisition is completed,
the system is put in an idle state. A new START must be given to
trigger a new acquisition. This mode is appropriate for capturing
events that occur only once such as the inrush current when turning
on a load.
Continuous (CONT)
This mode causes the trigger system to re-arm itself after each
trigger event. Every time a new trigger event occurs, new data is
acquired and the display is updated. No user intervention is required
after the initial START. This mode is appropriate for capturing
repetitive events or to monitor the source output continuously.
Trigger source
Trigger sources could be selected from the front panel using the SOUR(CE) field in the HARMONICS
menu of the MEASUREMENTS screen; refer to Figure 6-4.
Figure 6-4. HARMONICS Menu, Triggering
The following trigger sources are available in the HARMONICS menu:
Entry
Description
Immediate
This mode causes a trigger to occur as soon as the START field is
tapped. No trigger source needs to be specified for this trigger mode.
This mode is equivalent to the SCPI command, INIT:IMM:ACQ.
This trigger source is appropriate if no trigger condition is known or
desired. When using this trigger source, the acquisition is always
triggered.
124
M330000-02, REV-B
Asterion Series User Manual – 2U Models
Phase
6.3.3
California Instruments
This mode causes the acquisition system to wait for the zero phase
angle of the output voltage. The phase angle of the current with
respect to the voltage is determined by the load, so triggering at a
specific current phase angle is not possible, since it is not controlled
by the power source. However, when capturing current waveform
data, the phase relationship to the voltage can be determined easily
by triggering at the 0° point on the voltage.
Trigger delay
The trigger DELAY field allows setting the amount of pre- or post-trigger data that should be used when
positioning the data acquisition window with respect to the trigger event.
Entry
Description
POST-TRIGGER DELAY Positive trigger delay value means the acquisition window is delayed
by the amount of time specified. In this case, the actual trigger instant
itself is no longer present in the acquisition buffer. This condition is
shown in Figure 6-5, where a 20 ms trigger delay is used after
triggering on phase = 180°, with an output frequency of 50 Hz. The
trigger point is indicated by the dashed line; it occurs on the first 180°
point that occurs after the START field is tapped. Once the trigger
occurs, the acquisition holds off the specified 20 ms, after which the
data is captured. Using a positive trigger delay value always yields
post-trigger data. Positive trigger delay values may be set from 0.0
ms to 1000.0 ms (1 second) in 0.1 ms increments. The value may be
entered directly with the touch-screen keypad or using the rotary
encoder.
Figure 6-5. Post-Trigger (Positive Delay)
PRE-TRIGGER DELAY
M330000-02, REV-B
Negative trigger delay value may be specified up to the maximum
time depth of the acquisition window. The value may be entered
directly with the touch-screen keypad or using the rotary encoder.
The following time interval range is available: Negative trigger delay,
42.6 ms to 426 ms. This condition is shown in Figure 6-6 where a
20 ms trigger delay is used after triggering on phase = 0°, with an
output frequency of 50 Hz. The trigger point is indicated by the
dashed line; it occurs on the first degree point that occurs after the
125
Asterion Series User Manual – 2U Models
California Instruments
START field is tapped. Once the trigger occurs, the acquisition is
captured beginning from the specified 20 ms before the trigger point.
Using a negative trigger delay value always yields pre-trigger data.

7. Transient Programming
Transient programming provides a precise timing control over output voltage and frequency changes.
This mode of operation can be used to test a product for susceptibility to common AC and DC power
conditions such as surges, sags, brownouts and spikes. By combining transient list programming with
custom waveforms virtually any AC or DC condition can be simulated on the output of the power source.
Refer to Section 4.5.4 for specifics on using the display menus to program the transients from the front
panel. The full capability of transients programming could be accessed through the remote digital
interface using the Asterion Virtual Panels or SCPI commands; refer to the Asterion Series Programming
Manual P/N M330100-01 distributed on the CD, CIC496.
7.1 Using Transient Modes
Output transients are used to:
•
Synchronize output changes with a particular phase of the voltage waveform.
•
Synchronize output changes with internal or external trigger signals.
•
Simulate surge, sag, and dropout conditions with precise control of duration and phase.
•
Create complex, multi-level sequences of output changes.
•
Create output changes that have rapid or precise timing requirements.
The following power source functions are subject to transient control:
•
AC output voltage
•
DC output voltage
•
Frequency
•
Start phase angle
•
AC and DC voltage slew rate
•
Frequency slew rate
The following transient modes can be generated using the Asterion Virtual Panels or SCPI commands:

period.
generates a sequence of output changes, each with an associated dwell time or

turns off the transient functions; with SCPI commands, only the IMMediate
values are used as the data source for a particular function.
Figure 7-1 shows a representation of programming changes in the transient modes, and the output
waveform that is generated in each mode.
When a trigger is received in Step or Pulse modes, the triggered functions are set from their SCPI
command, IMMediate, to their TRIGgered value. In Step mode, the triggered value becomes the
immediate value. In Pulse mode, the functions return to their immediate value during the low portion of
the pulse. If there are no further pulses, the immediate value remains in effect. In List mode, the
functions remain at the last list value at the completion of the list. STEP, PULSe, and LIST modes are
not allowed to be mixed among functions.

7.1.1
Step Transients
Step transients specify an alternate or triggered voltage level that the AC source will apply to the
output when it receives a trigger. Because the default transient voltage level is zero volts, a
triggered voltage level must be entered before a trigger to the power source could change the
output amplitude. Step transients could only be programmed through the remote digital interface
using the Asterion Virtual Panels or SCPI commands; refer to the Asterion Series Programming
Manual P/N M330100-01 distributed on the CD, CIC496.
7.1.2
Pulse Transients
Pulse transients program the output to a specified value for a predetermined amount of time. At
the end of the Pulse transient, the output voltage returns to its previous value. Parameters
required to set up a Pulse transient include the pulse count, pulse period, and pulse duty cycle.
An example of a Pulse transient is shown in Figure 7-2. In this case, the count is 4, the pulse
period is 16.6 ms (for 60 Hz) and the duty cycle is 33%. Pulse transients could only be
programmed through the remote digital interface using the Asterion Virtual Panels or SCPI
commands; refer to the Asterion Series Programming Manual P/N, M330100-01, distributed on
the CD, CIC496.

7.1.3
List Transients
List transients provide the most versatile means of controlling the output in a specific manner as they
allow a series of parameters to be programmed in a timed sequence. Figure 7-3 shows a voltage output
generated from a list. The output shown represents three different AC voltage steps: 160 volts for
33 milliseconds, 120 volts for 83 ms, and 80 volts for 150 ms, separated by three intervals of zero volts
for 67 ms. The list specifies the pulses as three voltage points (point 0, 2, and 4), each with its
corresponding dwell points. The intervals are three zero-voltage points (point 1, 3, and 5) of equal time
duration. The count parameter causes the list to execute twice when started by a single trigger.
Transient list programming is supported through the front panel with the TRANSIENTS menu in the
OUTPUT PROGRAM screen; refer to Figure 4-16 and Figure 4-21. Transient lists can also be
programmed through the remote digital interface using the Asterion Virtual Panels or SCPI commands;
refer to the Asterion Series Manual P/N M330100-01 distributed on the CD, CIC496.
Figure 7-3. List Transients
To set up this type of transient list through the front panel, proceed as follows:
1. Navigate to the SETTINGS menu of the TRANSIENTS screen; refer to Figure 4-22. Set the
parameter values as follows:
Phase: A, B, or C
Time: sec
Volt(age): V
Freq(uency): Hz
Trig(ger): All
Step: All
Start Phase A: Zero
M330000-02, REV-B
129
Asterion Series User Manual – 2U Models
California Instruments
2. Tap on the TRIGGER sub-menu; refer to Figure 4-23. Set the parameter values as follows:
Phase Sync: All
Trig Out Source: BOT
Start Source: Immediate
3. Navigate to the VIEW menu of the TRANSIENTS screen; refer to Figure 4-24 and Figure
4-25.
4. Tap the ADD field to enter the ADD sub-menu; refer to Figure 4-26.
5. Tap the VOLTAGE SURGE/SAG selection button. Enter the following parameter values:
T(ime): 0.083 sec; the value is entered as seconds, with a minimum time resolution of
0.001 sec;
V(olts): 160 V; the surge voltage value;
To V(olts): 0 V; the voltage value following the surge;
Repeat: 0; number of times to repeat this transient event (not the entire transient list, as
describe in Step 10, below);
Function: Sine; output waveform
Trig: blank (no selection); not used in this example
Delay: 0.067 sec; time interval to remain at To V(olts) level.
6. Tap the SAVE field in the VOLTAGE SURGE/SAG sub-menu.
7. Repeat Steps 4 through 7 two more times using 120 V / 83 ms and 80 V / 150 ms as values.
8. Once the three events are programmed, navigate to the VIEW menu of the TRANSIENTS
screen to view all available events in the transient list. If more events are programmed than
could fit in the window, the arrow buttons on the right-side could be used to scroll through
the list. To edit an existing event, move the selection field to the relevant event number and
click the encoder switch to select it. Use the edit fields edit or delete the event, or to add
events before or after the selected one.
9. Navigate to the RUN menu of the TRANSIENTS screen; refer to Figure 4-21.
10. Tap the X Times selection button, and enter 1 in the X Times field. This will cause the
transient program to repeat once and thus run two times total. Do not confuse this global list
level repeat capability with the list event level repeat field mentioned in Step 5.
11. Tap the START field in the RUN menu of the TRANSIENTS screen. The transients list will
be executed two times, as shown in Figure 7-3. The power source will remain at the last
programmed value of the list (zero volts in this example).
7.2 Programming Slew Rates
As shown in the previous examples there are a number of ways that custom waveforms could be
generated. Programmable slew rates provide additional flexibility when customizing waveforms. Slew
rates determine how fast the voltage or frequency is changed by the controller when a step, pulse, or list
transient is triggered. Slew rates cannot be programmed from the front panel and are always set to their
maximum values at power-on. To use programmable slew rates, the power source must be programmed
through the remote digital interface using the Asterion Virtual Panels or SCPI commands; refer to the
Asterion Series Programming Manual P/N M330100-01 distributed on the CD, CIC496.

7.3 Switching Waveforms in Transient Lists
The FUNCTION field available in each transient list event setup menu may be used to dynamically
switch waveforms during transient execution. This allows different waveforms to be used during transient
execution. Waveforms may be switched without the output of the source being turned off.
Figure 7-4 illustrates the concept of using different waveforms at different steps in a transient list. In this
case, the change was programmed to occur at the zero crossing. Any phase angle can be used to start a
transient step however.
Figure 7-4. Switching Waveforms in a Transient List Transient Execution
A transient list can be executed from the RUN menu of the Transients screen; refer to Figure 4-21.
Tapping on the RUN selection-field will open the RUN menu; refer to Figure 7-5. A selection could be
made whether to run the transient list repetitively (Continuous button) or multiple times (X Times button).
To start a transient list, tap on the START field. The list will begin to run, and a new selection-field will
open, ABORT. A long duration transient could be stopped and aborted by tapping on the ABORT field
while a transient execution is in progress. For a short duration transient, this will likely not be visible, as
the transient will complete before the screen is updated.

7.4 Saving Transient List Programs
When the power source is turned off, the transient list that was programmed is not automatically saved.
Therefore, the programmed transient list would be lost if the unit is turned off. However, transient
programs could be saved in nonvolatile memory for later recall. This allows multiple transient list
programs to be recalled quickly without the need to enter all parameters each time. Transient lists are
stored as part of the overall power source operational configuration state in any of the available profile
state registers; refer to the CONFIGURATION screen in Section 4.5.5. To save a transient list, proceed
as follows:
1. After setting up a transient list, run it so that it is transferred to main memory.
2. Tap on the PROFILES field in the CONFIGURATION menu; refer to Figure 4-36.
3. Tap on one of the fifteen PROFILEx buttons (x = 0 to 14) to select it; refer to Figure 7-6.
4. Tap on the NAME field to open the NAME sub-menu to assign a unique name to the profile.
Otherwise, tap on the SAVE field to save the configuration state of the power source to a
profile memory register.
5. The profile could be recalled at a later time by selecting the appropriately selection-button,
and tapping on the LOAD field.

9. Service
9.1 Cleaning
Because the power source uses forced convection cooling, the air flow through the unit can pull in dust.
In environments having high concentrations of dust, periodic cleaning may be required. Disconnect AC
mains power to the power source before cleaning. The exterior of the unit should be cleaned with a mild
solution of detergent and water. The solution should be applied onto a soft cloth, and not directly to the
surface of the unit. To prevent damage to materials, do not use aromatic hydrocarbons or chlorinated
solvents for cleaning.
9.2 Basic Troubleshooting
Refer to the following tables for problems which might arise related to basic operation and connection of
the power source.
9.2.1
Excessive Output Voltage
Cause
External sense leads are not connected (if
selected).
Voltage at the AC/DC Output connector is
higher than that on Sense connector.
9.2.2
Poor Output Voltage Regulation
Cause
Unit is overloaded and in the
constant-current.
Unit is programmed to wrong voltage range
required for level of load current.
Remote Sense lines are not connected to
load.
9.2.3
Solution
Connect external sense wires to the rear panel AC/DC
Output/Sense connector.
If the External Sense is connected to the load, the voltage
output on Sense lines will be higher when the output is
loaded because of output cable voltage drop.
Solution
Remove overload to allow constant-voltage operation.
Select correct voltage range.
Connect Remote Sense lines to the load, and select
Remote Sense for the voltage sense method.
FAULT LED is On
Cause
Overcurrent (OCP) shutdown has occurred.
ALC control error has occurred.
Overtemperature (OTP) shutdown has
occurred.
M330000-02, REV-B
Solution
CV/CL mode is select; change to CV/CC;
If excessive load current for current setpoint, reduce load
current
ALC is not able to regulate output; select REG or OFF
mode; reduce output load.
Ensure that the air intake and exhaust are not block, and
that the ambient temperature at the power source air
intake is within the specification range
133
Asterion Series User Manual – 2U Models
9.2.4
California Instruments
Distorted Output
Cause
Load is drawing nonlinear currents.
The crest factor of the load exceeds 5:1.
9.2.5
Solution
Reduce load, or add power sources in parallel group.
Reduce load current peaks by reducing load, or add power
sources in parallel group.
Unit Shuts Down after Short Interval
Cause
Load has high inrush current, and exceeds
current setting in constant-voltage/currentlimit mode.
Output is short-circuited.
Remote sense leads are connected in
reverse polarity
9.2.6
Solution
Increase time delay for current-limit detection; add power
sources in parallel group to increase output current capability.
Remove output short-circuit.
Correct sense wiring.
No Output and Front Panel Display/LEDs are Off
Cause
Input AC mains is not connected.
There is no input AC mains power.
The AC mains voltage is inadequate.
If 1-phase input connection to the AC input
mains, wiring incorrect to AC input
connector.
9.2.7
No Output and Front Panel Display/LEDs are On
Cause
The OUTPUT switch is turned off.
Current setpoint is low or at zero.
Voltage setpoint is low or at zero.
REMOTE INHIBIT signal is shutting down
the output.
9.2.8
The OUTPUT switch is turned on.
Press OUTPUT switch, and ensure that the OUTPUT LED is
on.
Program current setpoint to higher value.
Program the correct output voltage.
Verify that the REMOTE INHIBIT signal is at the correct logiclevel to enable the output.
Solution
Press OUTPUT switch to toggle output to off, and ensure that
the OUTPUT LED is off. Changes in setting of AC/DC Mode or
Voltage Range could only be performed with the output off.
Parallel Group Faults When Master Output Switch is Turned On
Cause
Clock Config set to Auxiliary with Clock
Mode set to SYNC.
134
Solution
Setting of AC/DC Mode or Voltage Range is Not Accepted
Cause
9.2.9
Solution
Check mains disconnect switch.
Verify that mains power is available.
Verify that mains voltage is within specification limits.
Verify that correct terminals are used for 1-phase input mains
connection.
Solution
With Clock Config set to Auxiliary, Clock Mode must be either
Internal or External.

10. Error and Status Messages
Errors that occur during operation from either the front panel or the remote digital interface will result in
error messages. Error messages are displayed on the front panel display, and are also stored in memory
allocated to the error message queue. The error messages in the queue could be read using the SCPI
query command, SYST:ERR?. The error queue has a finite depth; if more error messages are generated
than can be held in the queue, a queue overflow message will be put in the last queue location. To
empty the queue, read out the error queue until the message, No Error, is received. Errors appearing on
the front panel display have a negative number, and will generally remain visible until the user moves to
another screen. If multiple error messages are generated in succession, only the last message will be
displayed.
Status message give information on the operational state of the power source. They appear on the front
panel with a positive number.
