Section I
Description
GENERAL
The Model 441A produces an ana-
log voltage that precisely repre-
sents the frequency of an applied
input signal. Adjustable “ input fre-
quency to output voltage” set
points allow the user to quickly
bracket the frequency of interest.
A unique crystal-controlled micro-
controller design provides fast re-
sponse, high conversion accuracy,
and low output noise that is inde-
pendent of frequency. In the oper-
ate mode, the front-panel display
shows the input frequency with up
to five-digit resolution. All oper-
ating parameters are set using the
display and only one other front-
panel control. It’s that easy. The
input-signal conditioner automat-
ically provides stable operation for
a wide range of pulse-, square-, and
sine-wave signals from under
10 mV to 100 V.
FEATURES
Reliable “state of
the art” design
The Model 441A combines the same rugged construc-
tion used in the Ectron 400 Series product line for the
last 30 years with the latest electronic and surface-mount
technology to produce a true breakthrough in frequency-
to-voltage conversion.
Designed in are rapid response to any change in fre-
quency, low output noise that is independent of input
frequency, and input-signal conditioning that automat-
ically provides correct operation for a great variety of
input signals, both in wave shape and amplitude.
Simplicity
Gone is the clutter of switches, knobs, pots, etc. asso-
ciated with other frequency-to-voltage converters. All
