Frequency-To-Voltage
Converter Ectron Model 441A produces an analog output
that precisely represents the frequency of an applied
input signal. Adjustable"input frequency to output voltage"
set points allow the user to closely bracket the frequency
of interest.
A unique crystal-controlled microcontroller design provides
fast response, high conversion accuracy and low output
noise that is independent of frequency.
The font-panel display shows the input frequency with
up to five-digit resolution. All operating parameters
are set using the display and one other front-panel control.
The input signal conditioner automatically provides stable
operation for a wide range of pulse-, square- and sine-wave
signals from under 10 millivolts to 100 volts in amplitude.
Three selections of input sensitivity and input bandwidth
are provided, plus a unique digital periodic filter that
cancels unwanted output variation caused by an input signal
whose frequency varies in a periodic manner.
Features:
• 1 Hz to 50 kHz Frequency Range
• Fast Response
• Crystal-controlled Accuracy
• Digital Periodic Filter
• Adjustable Input Sensitivity and Filtering
• Front-panel Display of Frequency to 5 Digits
• Precise Control of Output Voltage vs. Input Frequency
• Automatically Accepts 10 mV to 100 V Input Signal Range
• Output Noise Independent of Frequency
