INTRODUCTION
The Model AV-110G-PS variable-gain linear amplifier accepts input voltages in the
range of 0 to ±2V, and has a variable gain of +1 to +100. The maximum output voltage
is ±200V. The AV-110G-PS will drive load impedances of 50 kΩ or higher. The amplifier
bandwidth is 350 kHz.
This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.
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:
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) “Output resistance” is the internal resistance in series with output. Non-zero output impedances (ROUT) will reduce the
maximum output amplitude slightly when operating into low load impedances. That is, VOUT = VSET × RLOAD / (RLOAD +
ROUT), where VSET is the set amplitude and RLOAD is the load resistance.
2) These parameters can easily be adapted to meet special requirements. Contact Avtech (info@avtechpulse.com) with your
special application!
3) To specify the two channel option add the suffix -D to the model number.
4) To specify the regular DC offset option, add the suffix -OS to the model number.
5) Add the suffix -INV to specify the switchable gain polarity feature.
6) To specify the extended DC offset option, add the suffix -XOS to the model number.
7) 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
CC PART 18
This device complies with part 18 of the CC 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 (info@avtechpulse.com) 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 (info@avtechpulse.com) if you require assistance.

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 57 Watts. Please see the “ USES” 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: ailure 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:
