EIP Microwave 548B Frequency Counter, 10 Hz - 26.5 GHz

The EIP 548B Microwave Frequency Counter has a frequency range of 10 Hz to 26.5 GHz. The EIP 5448B also features automatic amplitude discrimination which enables the instrument to automatically select and measure the input signal with the highest level, and ignore all of the harmonics and other spurious signals that are present. "Frequency Limits" extend this signal selection capability by allowing you to select upper and lower limits. The EIP 548B will measure the frequency and power level of only the highest level signal within these limits - even if there are higher level signals present at the counters input. This gives you the ability to measure the frequency and power of a low level signal (such as a harmonic) even when a signal of much higher level (the fundamental) is present.
