1 INTRODUCTION

1.1 About this manual

This operation manual contains information that details installation, routine
maintenance and amplifier operation. It does not contain information needed for
servicing or calibration.

1.2 Amplifier description

The TESEQ CBA amplifier series is designed for laboratory use. The form factor
ranges from 3U, 4U & 6U bench top units up to rack mountable 10U amplifiers
consisting of a 7U power amplifier drawer and separate 3U power supply draw.

A CBA amplifier can be remotely controlled via the built in RS232, IEEE 488, USB or
Ethernet amplifier controller. Local control is via a front panel touch screen. This also
shows the amplifier status when controlled remotely.

A comprehensive performance and status indicating system is included. These
circuits monitor:

x Interlock circuit status
x Forward power indication
x Reflected power indication
x High VSWR indication
x RF baseplate temperature
x Ambient temperature
x Power supply DC voltage
x Power supply DC current
x Overall status of the amplifier

Visual indications are given. If a fault is detected, the amplifier automatically reverts
into a latched STANDBY condition. It remains in this condition unti l the fault has been
cleared and the fault latch is reset via the front panel touch screen.

The design of the amplifier is subject to continuous improvement. Consequently, the
amplifier may incorporate minor changes in detail from the information contained in
this manual.

2.3 Safety precautions

Observe all the following precautions to ensure personal safety and prevent damage
to the amplifier or equipment connected to it.

iWARNING! Properly dispose of the amplifier.
The RF amplifier modules in this equipment contain Beryllium Oxide, and other

components contain PTFE. The appropriate precautions and regulations must be
observed concerning the disposal of this amplifier and certain internal components.

Do not crush or incinerate.

Note: Beryllium Oxide is a material used in the manufacture of RF devices. Toxic

i

dust is given off when crushed.

Note: PTFE is a material used in the manufacture of certain components within the

amplifier. PTFE gives off toxic gasses when incinerated.
iWARNING! Do not touch the inner conductor of the RF-output connector.

High voltages can occur on the inner conductor of the RF output connector, or on
cables or antennas connected to it. These can cause RF burns if touched.

WARNING! Ground the amplifier.

The amplifier conforms with IEC Safety class 1, meaning that it is provided with a
protective grounding terminal. This is through the line supply cord to the centre pin of
the power inlet connector. To maintain this protection, the line supply cord must
always be connected to the source of line supply via a socket with a grounded contact.
Do this before making connections to the RF-input or RF-output connectors of the
amplifier.

Without the protective ground connection, all parts of the amplifier constitute a
potential shock hazard.

WARNING! Use the correct power cord.

Use only the line supply cord and connector specified for the amplifier. Use only a line
supply cord that is in good condition.

WARNING! Do not remove covers or panels.

To avoid personal injury, do not operate the amplifier without the panels or covers in
place.

WARNING! Do not operate in explosive atmospheres.

The amplifier provides no explosive protection from static discharges or arcing
components. Do not operate the amplifier in an atmosphere of explosive gasses.

or

iCAUTION!

Exercise caution when lifting.

iWARNING!

Use the safety interlock facility within danger areas.

i

CAUTION! Avoid static discharges

The RF input and output connections are static-sensitive and should not be subjected
to static discharge.

CAUTION! Use the correct line supply source

It is essential that the amplifier operates from a line supply source that does not apply
voltages and frequencies between the line supply conductors (or between either line
supply conductor and ground) that are outside the range detailed in the specification
sheet.

CAUTION! Do not obstruct the circuit breaker.

Ensure that there are no obstructions that impair the operation of the front panel line­supply circuit breaker(s).

CAUTION! Do not obstruct the airflow through the amplifier.

The cooling airflow is drawn in through the front and exhausted at the rear. If this
airflow is obstructed, overheating of the amplifier may occur.

CAUTION! Do not operate the amplifier outside its specification.

This may cause the amplifier to malfunction or be damaged.

iWARNING! Do not touch the exterior of the amplifier (rack mount version)
when in use.

The top and side panels of the amplifier can get hot during use, especially on high
power models.

CAUTION! Periodically replace the air-intake filters.

Operating the amplifier with the air filters dirty may cause the amplifier to overheat.

The appropriate lifting practices should be observed during transportation, installation,
or removal of the amplifier from its mounting position.

Any area where personnel may come into direct contact with high power RF, or be
exposed to non-ionising radiation, should be designated as a danger area. A barrier
should be established around any such area, with a switch in place when the barrier is
broken. This switch can be linked to the safety interlock BNC connector on the
amplifier, thus disabling the amplifier when the barrier is breached.

It is the responsibility of the operator to ensure that the working environment is safe.

The ‘safety interlock’ feature is provided to assist the purchaser in establishing such a
‘safe’ area.

i

iCAUTION!

Do not obstruct the airflow through the amplifi er.

iCAUTION!

Even though the ambient air temperature may be within the amplifier’s

specification, the internal temperature may rise above operational limits if it
is operated in direct sunlight.

3.1 General

Amplifier models that are very heavy have a caution label on the top cover.
Appropriate lifting practices should be observed during transportation, installation, or
removal of the amplifier from its mounting posit ion. When mounted in a rack, the
amplifier must not be supported by the front panel fixing holes alone. For easier
installation and removal, we recommend that the amplifier is positioned with its top no
more than 1.4 metres above ground level.

These should only be used for sliding the amplifier in and out on the rack.

i

Note: The amplifier may be lifted using the rear protection handles.

(See Section 12).
The amplifier is designed to be mounted in a 19” fixed rack installation. When mounted

in a rack, use a support tray-slider-assembly, especially for heavy amplifier models.
See the section 12 of this manual for details of amplifier dimensions.

mplifier with the front panel

At least 200mm clearance should be allowed behind the amplifier, so that air flow and
connecting cables are not obstructed. An unobstructed area of at least 200mm should
be allowed in front of the amplifier front panel air-intakes.

The cooling airflow is drawn in through the front and exhausted at the rear. If this
airflow is obstructed, overheating of the amplifier may occur. For correct amplifier
operation, airflow through the unit must be maintained.

CBA Manual: H012161 Rev: 3 9

iiCAUTION!

It is e

ssential that the amplifier operates from a line source that does not
apply voltages and frequencies between the line conductors (or between
either line conductor and ground) that are outside the range detailed in the
specification sheet.

iiCAUTION!

Ensure that the line cord does not interfere with the operation of the rear
panel line-input circuit breaker(s).

To improve EMC immunity, bond the amplifier to a good ground with a
conductor of 4 sq.mm or the equivalent earth braid, a ground post being
provided for this purpose on the rear panel. Although it provides an extra
measure of safety, this is

NOT a protective earth. The protective earth is the

ground pin on the line supply connector(s).

iiCAUTION!

Ensure that the RF source is OFF when making connections.

iiCAUTION!

Ensure any cables and connectors mating with the RF input and RF output
connectors are of

50-ohm impedance, and are designed to handle the power

at the frequencies generated by the amplifier. Although very similar,

75-ohm

connectors must not be used.

iiWARNING!

Use the safety interlock facility within danger areas.

3.2 Connecting the line cord

3.3 Connecting the chassis ground cable

3.4 Connecting the RF cables

Use cable with the lowest loss that is practical. The connectors should not be over­tightened, and any tightening instructions for the connector should be observed.
Ensure that any bends in cables conform to the recommended minimum-bend-radius
of those cables, especially where the cables enter the RF connectors.

3.5 Connecting the Safety interlock

If the amplifier is to be connected to an antenna, personnel may be exposed to non­ionising radiation. In such systems, the safety interlock function should be used.

Connection (via the rear panel) is with a BNC-type connector. We recommend that
shielded cable is used for all interlock connections to ensure EMC immunity.

The current in the safety-interlock circuit is less than 1mA, so cable with a low current
capacity is suitable.

CBA Manual: H012161 Rev: 3 10

If you do not need this function, fit the supplied BNC shorting-link in place. Failure to
do this will result in the amplifier latching in an “Interlock Open” status which switches
the amplifier into standby mode.

4 PROTECTION CIRCUITS

4.1 Over Heat Protection

The CBA RF components produce heat and are air cooled by fans. Should an over
heat condition occur for any reason, the CBA contains heat sensors that will shut
down the system via the amplifier control system. If the inlet and outlet openings are
obstructed, clear the obstruction and allow the amplifier to remain in standby so that
the internal fans can cool the amplifier down. Once the amplifier has reached an
acceptable temperature, depress the ”Fault Reset” soft key on the touchscreen and
the amplifier will operate normally.

4.2 Input Protection

The CBA series is designed to achieve the specified output power level (see
applicable datasheet) for an input level of 0 dBm or less (1.0mW) however, to prevent
overdriving the amplifier, the Input Protection circuit will activate if the input signal
exceeds 10 dBm and will automatically compensate for the increased input signal by
reducing the gain of the preamplifier. Even though the amplifier has an Input
Protection Circuit, overdriving the amplifier is not recommended.

IMPORTANT NOTE:
The CBA Sample Port connectors must be either connected to a 50Ω measurement

system or terminated with the supplied 50Ω load. If the CBA is operated without 50Ω
impedance on the Sample ports, the metering and output protection may be
inaccurate, which may result in damaging the amplifier and voiding the unit’s warranty.

4.3 Power Supply Faults

The Power Supply Fault circuit monitors the voltage and current of system power
supplies and produces a fault indication should any voltage or current level deviate
from normal operating parameters. Each power supply voltage output is monitored
and displayed to indicate the power supplies are operating within design parameters.

4.4 Mismatch Protection

The amplifier is not damaged by using it into a load that has a poor VSWR. While
operating into a load that has poor VSWR, the amplifier may not deliver specified
output power. In extreme cases, the amplifier folds back to protect internal circuitry.

CBA Manual: H012161 Rev: 3 11

iiCAUTION!
Ensure that all the installation procedures detailed in Section 3 are complete
before operating the amplifier.

iiCAUTION!
Ensure that before connecting or turning the RF source ON, the

source
peak output level is set to less than the maximum level detailed adjacent to the
RF input connector(s).

ii

WARNING!

Use the safety interlock f

unction within danger areas.
Any area where personnel may come into direct contact with high power RF, or
be exposed to non

-ionising radiation, should be designated as a danger area.

A barrier should be established around this area, with a switch

opening when

the barrier is broken.

This should be linked to the safety interlock connector,
disabling the amplifier when the barrier is breached. (It is the responsibility of
the operator to ensure a safe working environment).

i

5 AMPLIFIER OPERATION

5.1 Safety interlock Operation

input-

Safety interlock connections are via a BNC connector on the rear panel. This should
be used with an appropriate switching or control arrangement so that the amplifier is
disabled when any barrier to a dangerous area is broken. Once the interlock
connection is broken the amplifier will default to standby mode. Once the interlock
connection is remade the amplifier will automatically resume operation in “Operate
Mode”

5.2 Switching on line supply

After ensuring that the amplifier front panel rocker switch is in the down position (off)
ensure the mains lead is connected to the correct AC line source. Depending on the
model of CBA,

1 Switch the rear panel 3 phase circuit breaker to the “On” position. The rear

panel circuit breaker provides AC overcurrent protection. There will be no
amplifier indication as a result of this step.

2 Switch the front panel rocker switch to the Up (On) position. The touchscreen

will indicate that the boot up process has begun.

i

Hints and tips: This switch can remain in the ON position all the time, but it is best

set to OFF when the amplifier is not being used for long periods.

CBA Manual: H012161 Rev: 3 12

i

5.3 Cooling Fan Operation

Once the amplifier has been turned on, the power supply fan will start along with the
rear panel cooling fans. The CBA B series uses a forced air cooling system where air
is drawn in to the front grill and exhausted out of the rear of the amplifier. Temperature
sensitive fan circuits are used for optimal audible noise when the amplifier is in use.
When in standby mode the fans will operate at their s lowest speed, once the amplifier
is set to, “Operate” mode, the RF modules will be enabled and start to generate heat.
The fans will slowly increase in speed until the amplifier has reached thermal
equilibrium.

Hints and tips: The air intake/exhaust should be kept clear at all times. If they are

i

blocked for any reason the amplifier will overheat and fault latch. Once the internal
amplifier temperature has cooled to within normal operating conditions the fault can be
reset and normal operation resumed.

5.4 General

When the front panel rocker switch is
switched Up to the, “ON” position the
Teseq splash screen will appear on the
touch screen display. The amplifier will
remain in this state for a maximum of 45
seconds while the amplifier controller
completes its boot sequence.

5.5 OPRT/STBY

The operate/standby button controls the
RF On/Off function of the amplifier. In
standby the DC power supply is in the,

“Off” state and the amplifier is in standby

mode (RF Off).

CBA Manual: H012161 Rev: 3 13

Once pressed the OPRT/STBY button
will illuminate green. This will indicate the
DC power supply has energised
supplying voltage to the power modules
and the amplifier is in, Operate mode
(RF On)

5.6 FLT/RST

The Fault/Reset (FLT/RST) will illuminate
red when a fault is detected. Once the
fault is removed/fixed depressing the
FLT/RST will clear the fault indication so
that normal operation of the amplifier can
resumed.

5.7 LOC/RMT

When the amplifier recei ves a remote
command the LOC/RMT will illuminate
green. Depressed the button will restore
the amplifier to local operation

5.8 Gain Control

The gain control button allows for gain
adjustments over the entire operating
frequency of the amplifier over a range of
30dB in 100 steps via the touch screen.

8 REMOTE CONTROL CONNECTIONS & OPERATIONS.

8.1 Connectors

IEEE 488.2 24 Way IEEE connector
RS232 9 pin female D-type
LAN RJ45 with signalling LED’s
USB USB-B device connector

8.2 IEEE 488 Operation

The Teseq Amplifiers can be operated remotely from a computer having an IEEE-488
interface. This interface allows the amplifier to be remotely controlled over the
General-Purpose Interface Bus (GPIB) by sending commands to the amplifier.
Additionally, amplifier status and forward and reverse power readings may be read
over the GPIB. All functions can be controlled by coded messages sent over the
interface bus via the 24-pin socket connector on the rear panel of the unit. The GPIB
command codes for the TESEQ Amplifier series are discussed on subsequent pages
and, for ease of identification; the command codes are identified within the text by bold
capital characters. For full information on the IEEE protocols and syntax the IEEE-

488.2 Standard should be consulted

.

When the amplifier receives a command over the GPIB, it automatically switches to
REMOTE operation, pressing the LOCAL key on the front panel returns the unit to
normal manual local operation. The initial state of the amplifier after power-on is the
full attenuation condition.

Note: The ZEROATT command must be set in order for the amplifier to be able to

i

generate output power.
The GPIB address of the amplifier is set by via the Front panel using the touch screen

control button.

8.3 RS-232 Operation

For operation of the serial port a terminal application is required to be configured with
the following port configuration. Connect the RS232 cable and power the amplifier up.

Note: To determine which COM port is being used for a specific protocol, navigate to
CONTROL PANEL and double-click on the SYSTEM icon. Once under System
Properties, navigate to the HARDWARE tab and select DEVICE MANAGER. Scroll

down until you see PORTS (COM & LPT) and expand the drop-down menu. The
associated port should be listed.

Note: Teseq doesn’t recommend the use o f USB to serial ada ptors unless the ad aptor
contains an FTDI chip set.

displayed on the computer.

8.4 Ethernet Connection

With the amplifier powered down connect via an Ethernet cable to the network. Power
the amp up and wait (5/10 seconds) for the amplifier to acquire an IP address
dynamically. The acquired IP address will then be displayed on the touch screen in the
top right-hand corner.

i

Note: The port number is 10001 and a DCHP server is required to address the
amplifier.

To assign a static IP to the ampli fier, you must first esta blish a re mote conn ection. Once
connected, type the command Settings to enter the User Settings Mode. Once in this
mode, you can enter the command Edit to begin configuring the static IP settings. The
Edit Settings Values are as follows:

CBA Manual: H012161 Rev: 3 21

8.5 USB Connection

Note: A USB cable with an FTDI chip set is required for this form of communication.

FTDI drivers are required to assign the USB interface a virtual com port. If these are
not installed on the PC in use they can be downloaded from,

http://www.ftdichip.com/FTDrivers.htm

Ensure the drivers are loaded and installed on the PC in use before connecting via
USB. With the amplifier powered down connect to the USB interface. Power the
amplifier up and the interface will be assigned a virtual com port. The COM Port
number can be discovered as per the RS232 method (8.3). Again, a terminal
application will be required to communicate with the amplifier using the same setting
as per the RS232 method (8.3)

iiCAUTION!

Do not use cleaning materials that leave a residue or that are abrasive for
cleaning the RF connectors, as this seriously degrades their performance.

iiCAUTION!

Operating the ampl
to overheat.

9 ROUTINE MAINTENANCE

9.1 General cleaning

For cleaning the front panel, use an anti-static foam cleaner and a soft lint-free cloth or
tissue. Using abrasive materials or strong solvents may damage the surface finish or
the front panel overlay.

9.2 RF connectors
If the RF connectors are used frequently, or left disconnected for long periods, there is

a tendency for dirt and oxide deposits to build up. This increases the contact
resistance and creates localised heating of the RF OUT connector pin, which may
cause damage on high power models. Periodically inspect the inner pins of the RF
connectors for damage or deposits, and carefully clean if required.

When storin g the amplifier for long periods, the RF connectors should be pr otected
with the plastic covers provided.

9.3 Air-filter cleaning.

ifier with the air-filter clogged, may cause the amplifier

The air-intake-filter on the amplifier front panel should periodically be checked for
cleanliness. If it is seen to be obstructed with any dust or debris this should be cleaned
away before the amplifier is operated.

CBA Manual: H012161 Rev: 3 24

10 FAULT FINDING

i

i

10.1 General checks

These are simple checks the user can perform to establish the cause of any amplifier
malfunction. The following procedures are by no means comprehensive, and do not
disclose any obscure fault with the amplifier or any system it may form a part of.

Amplifier Won’t Power Up at Mains Switch on.

x Ensure that the line cord is properly installed.
x Ensure that the line cord or connector is not damaged.
x Ensure that the 3-phase line circuit-breaker (model dependent) and front panel

rocker switch is switched on.

x Ensure that the line circuit-breaker is not in the tripped condition.

i

Note: If the line circuit-breaker trips, there is a fault with the power supply and the
amplifier must be returned to TESEQ for repair. There are no user-replaceable fuses
in the amplifier.

No RF Output
x Ensure that the correct safety interlock signal is present. If the Interlock facility is

not used, ensure that the Interlock shorting-link (rear panel) is inserted.

x Ensure that the touch screen Operate/Standby button is illuminated green.
x Ensure that the RF cables and connectors are mated correctly.
x Ensure that there is no damage to any of the RF connectors or cables, especially

where the cable enters the connector.

x Ensure that the touch screen FLT/RST fault light is not illuminated red.
x Ensure that the RF input level is within specification.

RF present but at reduced level

x Ensure that the gain control is set to 100%
x Ensure that the RF cables and connectors are mated correctly.
x Ensure that the inner pins of the RF connectors are clean.
x Ensure that the RF load is 50 ohms.
x Ensure that there is no damage to any of the RF connectors or cables, especially

where the cable enters the connector.

x Ensure that the RF input level is within specification and that the gain adjustment is

set as expected.

Note: If the above checks have been done and the RF output is still at reduced level,
there is probably a fault with the RF modules, in which case the amplifier must be
returned to TESEQ for repair.

CBA Manual: H012161 Rev: 3 25

i

i

Amplifier not responding to remote commands

x Ensure that the remote connector is mated properly.
x Ensure that the ‘REMOTE’ indicator is illuminated on the touch screen. If not, send

a, “OPRT” command.

x Ensure that there is no damage to the remote connector or cable, especially

around where the cable enters the connector.

10.2 Fault indications
HIGH VSWR

High VSWR is seen when high levels of output power are reflected into the amplifier.
The internal diagnostics determine if this state exists.

Note: The amplifier will not be damaged by using it with a high VSWR. It might be

i

that the load naturally has a poor VSWR – this just means that the full output power of
the amplifier cannot be delivered to the load. The function of the indication is not to
protect the amplifier. It is there to alert the operator that there has been a change in
the system operating conditions.

x Ensure that the RF cables and connectors are mated correctly.
x Ensure that the RF load is 50 ohms.
x Ensure that the inner pins of the RF connectors are clean.
x Ensure that there is no damage to any of the RF connectors or cables, especially

around where the cable enters the connector.
Interlock
Is indicated on the display in the amplifier status section when the continuity of the

safety interlock circuit is broken, or the interlock control signal is not present.
x Ensure that there is continuity through the safety interlock switch and wiring (if

used).

x Ensure that the safety interlock connector or shorting-link is properly mated.
x Ensure that the safety interlock control signal is present.

Note: If no external safety interlock switch or control signal is used, connect the

safety interlock shorting-link (rear panel).
Power Supply fault
When the power supply voltage or current is outside operational limits, a power supply

fault is illuminated and the system enters standby mode.
x Ensure that the power supply air-filter insert is not clogged or obstructed. Clean as

necessary.

x Ensure that the ambient temperature is within the amplifier specification.
x Ensure that there is at least the recommended clearance around the front and rear

panel air vents.

CBA Manual: H012161 Rev: 3 26

i

i

x Ensure that for amplifier models with multiple line-input connectors, all connectors

are connected to the line supply.
x Ensure that for models with more than one power supply, that all the rear panel

circuit breakers are set to the ON position.

i

Note: If the supply fault indicator is due to a high-temperature condition, cool the
power-supply by leaving the amplifier in, “STANDBY” mode. The power-supply
cooling fan (internal to the power-supply) can then reduce the power-supply
temperature. If the supply fault indicator remains illuminated when the power-supply
has cooled down, return the amplifier to TESEQ for repair.

Thermal Fault
A thermal fault is indicated on the display in the amplifier fault section when the

temperature of the modules has risen above operational limits.

x Ensure that both rear panel fans are operating and not obstructed.
x Ensure that the air-filter inserts are not clogged or obstructed. Clean or replace if

necessary.

x Ensure that the amplifier is not operating in direct sunlight.
x Ensure that the ambient temperature is within the amplifier specification.

x Ensure that there is at least the recommended clearance around the front and rear

panel air vents.

Note: To cool the RF modules down, leave the amplifier in the RF STANDBY
condition so the cooling fans can reduce the RF module temperature. If the fans are
not operating, or this indicator remains illuminated when the RF modules have cooled
down, return the amplifier to TESEQ for repair.

If, after fault-finding, problems persist, contact TESEQ by telephone, fax or E-mail. It
may be necessary to return the equipment to TESEQ for repair. See the Appendix 2
for details on how to do this.
