INTRODUCTION

Models AV-110B-PS-D and AV-110G-PS-D are variable-gain dual-channel linear
amplifiers.

The gain for each of the two independent channels may be adjusted from +1 to +100.
The input range is 0 to ±2V, and the output range is 0 to ±200V. The outputs can drive
load impedances of 50 kΩ and higher.

The amplifier bandwidth is DC-100 kHz for model AV-110B-PS-D, and DC-350 kHz for
model AV-110G-PS-D.

HIGH-VOLTAGE PRECAUTIONS

CAUTION: This instrument provides output voltages as high as ±200 Volts, so

extreme caution must be employed when using this instrument. The instrument should
only be used by individuals who are thoroughly skilled in high voltage laboratory
techniques. The following precaution should always be observed:

5

1) Keep exposed high-voltage wiring to an absolute minimum.

2) Wherever possible, use shielded connectors and cabling.

3) Connect and disconnect loads and cables only when the amplifier is turned off.

4) Keep in mind that all cables, connectors, oscilloscope probes, and loads must
have an appropriate voltage rating.

5) Do not attempt any repairs on the instrument, beyond the fuse replacement
procedures described in this manual. Contact Avtech technical support (see
page 2 for contact information) if the instrument requires servicing.

1) To specify the DC offset option, add the suffix -OS to the model number. The sum of the amplitude and the offset must remain
within the rated output amplitude range – i.e., this option does not change the minimum or maximum obtainable output voltage.

REGULATORY NOTES

FCC PART 18

This device complies with part 18 of the FCC rules for non-consumer industrial,
scientific and medical (ISM) equipment.

This instrument is enclosed in a rugged metal chassis and uses a filtered power entry
module (where applicable). The main output signal is provided on a shielded connector
that is intended to be used with shielded coaxial cabling and a shielded load. Under
these conditions, the interference potential of this instrument is low.

If interference is observed, check that appropriate well-shielded cabling is used on the
output connectors. Contact Avtech ([e-mail]) for advice if you are unsure
of the most appropriate cabling. Also, check that your load is adequately shielded. It
may be necessary to enclose the load in a metal enclosure.

If any of the connectors on the instrument are unused, they should be covered with
shielded metal “dust caps” to reduce the interference potential.

This instrument does not normally require regular maintenance to minimize interference
potential. However, if loose hardware or connectors are noted, they should be
tightened. Contact Avtech ([e-mail]) if you require assistance.

EC DECLARATION OF CONFORMITY

We Avtech Electrosystems Ltd.

P.O. Box 5120, LCD Merivale
Ottawa, Ontario
Canada K2C 3H4

declare that this pulse generator meets the intent of Directive 89/336/EEC for
Electromagnetic Compatibility. Compliance pertains to the following specifications as
listed in the official Journal of the European Communities:

EN 50081-1 Emission

EN 50082-1 Immunity

8

and that this pulse generator meets the intent of the Low Voltage Directive 72/23/EEC
as amended by 93/68/EEC. Compliance pertains to the following specifications as listed
in the official Journal of the European Communities:

EN 61010-1:2001 Safety requirements for electrical equipment for

measurement, control, and laboratory use

DIRECTIVE 2002/95/EC (RoHS)

This instrument is exempt from Directive 2002/95/EC of the European Parliament and
of the Council of 27 January 2003 on the Restriction of the use of certain Hazardous
Substances (RoHS) in electrical and electronic equipment. Specifically, Avtech
instruments are considered "Monitoring and control instruments" (Category 9) as
defined in Annex 1A of Directive 2002/96/EC. The Directive 2002/95/EC only applies to
Directive 2002/96/EC categories 1-7 and 10, as stated in the "Article 2 - Scope" section
of Directive 2002/95/EC.

DIRECTIVE 2002/96/EC (WEEE)

European customers who have purchased this equipment directly from Avtech will have
completed a “WEEE Responsibility Agreement” form, accepting responsibility for WEEE
compliance (as mandated in Directive 2002/96/EC of the European Union and local
laws) on behalf of the customer, as provided for under Article 9 of Directive
2002/96/EC.

Customers who have purchased Avtech equipment through local representatives
should consult with the representative to determine who has responsibility for WEEE
compliance. Normally, such responsibilities with lie with the representative, unless other
arrangements (under Article 9) have been made.

Requirements for WEEE compliance may include registration of products with local
governments, reporting of recycling activities to local governments, and financing of
recycling activities.

INSTALLATION

VISUAL CHECK

After unpacking the instrument, examine to ensure that it has not been damaged in
shipment. Visually inspect all connectors, knobs, and handles. Confirm that a power
cord is with the instrument. If the instrument has been damaged, file a claim
immediately with the company that transported the instrument.

POWER RATINGS

This instrument is intended to operate from 100 - 240 V, 50 - 60 Hz.

The maximum power consumption is 90 Watts. Please see the “FUSES” section for
information about the appropriate AC and DC fuses.

This instrument is an “Installation Category II” instrument, intended for operation from a
normal single-phase supply.

CONNECTION TO THE POWER SUPPLY

An IEC-320 three-pronged recessed male socket is provided on the back panel for AC
power connection to the instrument. One end of the detachable power cord that is
supplied with the instrument plugs into this socket. The other end of the detachable
power cord plugs into the local mains supply. Use only the cable supplied with the
instrument. The mains supply must be earthed, and the cord used to connect the
instrument to the mains supply must provide an earth connection. (The supplied cord
does this.)

Warning: Failure to use a grounded outlet may result in injury or death due to
electric shock. This product uses a power cord with a ground connection. It must be
connected to a properly grounded outlet. The instrument chassis is connected to the
ground wire in the power cord.

The table below describes the power cord that is normally supplied with this instrument,
depending on the destination region:
