With over 15,000 units sold in Europe, the HM8021-3 brought new dimensions to the price/performance ratio available in universal counters. With this new model, HAMEG continues to lead the market in high performance, low price counters. This microprocessor-based instrument has built-in self-test as well as two high sensitivity inputs, with an extended frequency range to 1.6GHz for one of them.

The reciprocal frequency measurement technique provides high resolution of low frequency signals with at least seven significant digits for a 1s measurement duration. The HM8021-4 is equipped with an extremely stable temperature compensated crystal oscillator (TCXO) with a stability of 0.5 ppm over the entire operating temperature range. Readings of frequency, period, time interval and totalized count, up to 99,999,999, combined with the Display Hold function and a full range offset makes this instrument ideally suited for a broad range of applications.

The Auto Trigger function allows for accurate measurements to be made, even on noisy waveforms and those with extremely short duty cycles. The HM8021-4 provides variable trigger control, offers selectable 20dB attenuation and AC or DC coupling to simplify measurements on complex signals.

When comparing the HM8021-4 to other instruments of it's price range you can easily see what makes the HM8021-4 such an outstanding value.
