The Rohde & Schwarz HM8021-4 is a Universal Frequency Counter that leads the market in high performance, low price counters. This microprocessor-based instrument has a built-in self-test as well as two high sensitivity inputs, with an extended frequency range from 0Hz to 1.6GHz.
The reciprocal frequency measurement technique provides high resolution of low frequency signals with at least seven significant digits for one second measurement duration. The HM8021-4 is equipped with an extremely stable Temperature Compensated Crystal Oscillator (TCXO) with a stability of 0.5ppm 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 its price range you can easily see what makes it such an outstanding value product.
