The Vibration Exciter Control Type
1050 is a digital instrument for use as a
sinusoidal sweep controller of electro-
dynamic vibration exciter systems. The
IEEE interface and frequency genera-
tion resolution to 1,19mHz makes the
Type 1050 a flexible and highly accurate
instrument. It forms the basis of an ana-
lyzing system which has specific appli- .
cation to engineering development and
prototype testing; quality control; reso-
nance dwell testing and vibration trans-
ducer calibration.

The instrument is very easy to use
and as an introduction to the operating
procedure it uses a step-by-step se-
quence to guide the user through the
test set-up parameters. The provision of
both a direct-entry keyboard and
thumb·,rheel control allows fast and pre-

setting of the test parameters. Test
!'
c-up parameters can be stored and re-
,alled instantly from any of the 4 non-
volatile memories.

General Description
The Type 1050 is a controller con-
taining a digitally controlled genera-
tor, a vibration meter enabling accu-
rate measurement and control of any
vibration measurement parameter and
a compressor for regulation of the vi-
bration exciter excitation. The front
panel is divided into these three sec-
tions with each section containing an
LED display for use during setting
and monitoring of the vibration test
parameters.
