960

&

960B

instruments are single channel wideband high-

gain amplifier instruments.

The bandwidth is

adjustable from 10 Hz to 1 MHz wide and the

gain can be set from 0 dB to 80 dB in 1 dB steps.

The Amplifier has an input impedance of 1 M

Ω

shunted by 47pF in single ended mode and 2 M

Ω

shunted by 47pF in differential ended mode. The

common mode rejection ratio (CMRR) is greater

than 55 dB in differential mode.

Standard operational features include:

Adjustable gain to 80 dB

Adjustable bandwidth to 1 MHz

Differential or single ended input

Differential or single ended output

Output can drive 50

Ω load

Off-set adjustment

Overload indicator

BNC Connectors for all I/O

The optional battery powered 960B is particularly

well suited to applications requiring isolation from

an electrically noisy primary power source.

Compact size and manual rotary switch front

panel controls makes the 960 amplifier a popular,

cost effective, easy-to-use solution for signal

conditioning applications in the following areas:

Biomedical Applications

Data Recording/Playback

EKG/EEG Data Amplification

Medical Research

Seismic Analysis

Vibration Analysis

Communications
