Oscilloscope 251 Instant

High-speed RF component verification.

In the world of radio frequency (RF) and high-frequency digital design, accurate frequency measurement is crucial. While oscilloscopes provide visual representations of signals, they are often limited in frequency precision. The (often referred to in the context of the "251" series) fills this gap as a high-performance 1.3 GHz multifuntion counter designed to measure frequency, period, and pulse width with exceptional stability and accuracy.

The CMC251's internal temperature-compensated, crystal-controlled time base provides ±1plus or minus 1

The instrument offers a low-pass filter on Channel A (-3 dB at 100 kHz) to improve low-frequency measurements by minimizing high-frequency noise. It also allows for attenuation (3 V to 42 V) on Channel A to handle higher amplitude signals. Typical Applications of the CMC251
