The CNT-66 and CNT-69 are high-quality,
easy-to-use budget counters for accurate
and reliable measurements. The units use
reciprocal frequency counting, giving 7-8
digits resolution even on low frequency
measurements. The optional high-stabil-
ity MTCXO time base has a stability in
the order of 0.1 ppm.
The no-compromise input design of
these counters, provide smart auto trig-
gering to handle any type of input signal,
plus variable sensitivity and other noise
immunity functions. The counters are
rugged, input-protected and reliable with
exceptional MTBF figures of up to
70000h. They have excellent EMC
performance.
The optional GPIB interface turns CNT-
66 into the lowest cost, fully programma-
ble timer/counter available from any
quality manufacturer.
CNT-66 Timer/Counter
The CNT-66 is a 100% GPIB-programmable
timer/counter. All counter functions includ-
ing also trigger level and sensitivity settings
are GPIB-controlled. The bus-learn mode
makes programming faster and easier.
Error-Free Triggering
Trigger level setting can be automatic on all
input signals. The trigger level can be
displayed immediately with one keystroke,
and input triggering is instantly checked with
the tri-state LED trigger indicators. Input
sensitivity (noise immunity) is selectable
from 20 mV to 1V.
V p-p measurements up to 50 MHz
The CNT-66 has Volt peak measurements up
to 50 MHz. Both the minimum and the maxi-
mum signal peaks are displayed simultane-
ously.
CNT-69 Frequency Counter
The multi-function CNT-69 performs
frequency, period, totalize, pulse width and
frequency ratio or difference measurements.
The CNT-69 can be used for frequency meas-
urements on the bench or in the field. It is
easy to operate including a.o. also blanking of
irrelevant display digits to make it easy to
read results.
MTCXO Time Base
(Mathematically Temperature Compensated
Crystal Oscillator)
The optional high stability MTCXO time-
base offers a stability, comparable to standard
oven oscillators, but at a much lower cost.
The temperature dependency of the individ-
ual crystal is stored in a non-volatile memory
and used for immediate compensation of the
displayed value. Unlike oven oscillators, an
MTCXO gives high accuracy instantly, with-
out long warm-up times.
Calibration and adjustment is very easy. Just
connect the frequency standard and push a
button. There is no trimmer to be turned.
