DESCRIPTION
GENERAL
The Model 560H amplifier is a wideband, true
differential dc instrumentation amplifier. It offers a
high level of performance at a moderate cost for a
wide variety of applications. The compact design
features outstanding linearity, gain stability, and
input impedance. Excellent overall accuracy is
assured due to direct coupling and very high loop
gains. The internal circuitry uses discrete compo-
nents and integrated circuits to provide “state of
the art” performance while keeping the cost and
complexity to a minimum. The low power con-
sumption reduces warm-up time and component
aging due to internally-generated temperature rise.
All components are mounted on a single circuit
card. Certain options are included on smaller
circuit cards, which are plugged into the amplifier
circuit card. The output of the basic amplifier is
±10 V at 10 mA. Filtered outputs and high-current
capability are available options.
MODEL 560H FEATURES

A switch-selectable 100:1 input divider.

A switchable RTO-zero range control with
ranges of 0.1 V, 1 V, and 10 V.

Front-panel output-monitor jacks.

Optional filtered output of 10 Hz, 100 Hz,
1 kHz, 10 kHz, and wideband front-panel
switch-selectable positions.

Optional 100 mA peak (50 mA rms or dc)
output on either wideband or filtered output.
AVAILABLE AMPLIFIER OPTIONS
Option J
Wideband output of ±10 V at 10 mA.
Option K
Wideband output of ±10 V at 100 mA rms or
dc output. (See Footnote 1 on Page 2-2.)
Option L
Wideband output of ±10 V at 10 mA and a
selectable filtered output of ±10 V at 10 mA.
Option M
Wideband output of ±10 V at 100 mA rms or
dc and a selectable filtered output of ±10 V at
10 mA. (See Footnote 1 on Page 2-2.)
Option N
Wideband output of ±10 V at 10 mA and a
selectable, filtered output of ±10 V at 100 mA
rms or dc. (See Footnote 1 on Page 2-2.)

ENCLOSURES
Enclosures are supplied with a three-wire power
cord and mating connectors for the amplifier inputs
and outputs unless stated otherwise.
E513-2A
This enclosure with integral power supplies
will accept up to two Model 560H units and is
intended for bench or portable use. All connec-
tions except input power are made to barrier
strips on the rear of the enclosure. A rear-panel
switch is used to inhibit the operation of the
zero-detector LED’s in all amplifiers. The
