Oscilloscope 251 Repack – Editor's Choice

Frequency, Period, Totalize, and Pulse Width.

Channel B is specifically engineered for high-frequency applications, handling signals from 80 MHz up to 1.3 GHz. With a sensitivity of 5 mVRMS (80 MHz to 600 MHz) to 35 mVRMS (900 MHz to 1.3 GHz), it is perfect for testing RF circuits and transmitters. 2. Versatile General Purpose (Channel A) oscilloscope 251

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 Frequency, Period, Totalize, and Pulse Width
