Pen-Type RF Frequency Counter - 1 kHz to 200 MHz

Check a suitable signal's frequency with a compact probe-style counter. This 1kHz-200MHz unit brings a digital readout to the test point with selectable gate times.

✅ Read frequency close to the circuit - The probe format gives a direct connection arrangement for a suitable signal.

✅ Choose the measurement interval - Two gate times give you different display-resolution choices for the check.

✅ Filter an unstable indication - The invalid-signal setting can suppress readings the unit treats as unstable.

Match the Signal Before Taking the Reading

An oscillator or low-level RF check needs the test signal to fit the counter's input limits. Use the appropriate connection method and reference while recording the result alongside the circuit conditions.

The specified signal range is 0.2-3Vpp. This is not a mains voltage probe. Power it from the stated 5V USB-A-to-Type-C arrangement; fast-charge cables and sources are not supported by the description. Calibration requires a suitable reference.
