FREQUENCY COUNTER

Frequency Counter

Frequency counter is an electronic instrument, that is used for

measuring frequency of an input signal. Frequency counters are

commonly used in laboratories, factories, and field environments to

provide direct frequency measurements of various devices.

Frequency Counter

In the early 1950s, the frequency counter was developed. The

device could measure and accurately indicate frequencies up to 10

MHz. Present-day frequency counters can accurately read frequencies

as high as 40 GHz. In addition to direct frequency measurement

indication, some types of frequency counters can measure the WAVE

PERIOD; RATIO; and TIME INTERVAL.

frequency counter HP 5315A is the best !!! That’s right !!!

Ooh..., of course!!!

How to Use Frequency Counter

First Step

• Connect oscillator to frequency counter using the BNC cable

oscillator

• Turn oscillator and frequency counter power on

Second Step

Third Step

• Select a pure, unmodulated waveform from the oscillator: sine, triangle, or pulse.

Fourth Step

• Set the oscillator's amplitude (output level) about halfway. Set its frequency to about 1000 Hz.

Fifth Step

• Set the frequency counter to the lowest frequency range. Set its gate to one per second. If it has a frequency/period mode, set it to frequency.

Sixth Step

• If the frequency counter has a "Hold" button, press it. The display should hold the same count. Press "Hold" again to resume normal operation.

Seventh Step

• If you want to get new frequency from Oscillator, change the oscillator frequency. The counter should show the new frequency momentarily.

Eighth Step

• Change the "Gate" setting. The display should update less often but with higher resolution.

conclusion

A frequency counter is one of the easiest to use. Their main purpose, measuring frequency, is done by setting a few front panel switches.

Tips

For best performance, give the frequency counter a few minutes of power-on time to stabilize before

use.
