Featured Product

Phase Matrix's 25B and 28B frequency counters are currently priced to stimulate the economy, making them the best deal in their class. These portable, rugged counters are ideal for communications applications. They precisely measure CW, FM, AM, and other complex modulated frequencies from 10 Hz to 20 GHz (25B Model) and up to 26.5 GHz (28B Model).

Furthermore, these frequency counters can simultaneously measure and display an individual input signal's frequency and power level in a multi-signal environment. EIP counters have been chosen by the DoD and other governmental agencies as well as defense contractors for over 30 years. EIP® instruments are the ones you can count on!

EIP® 28B Frequency Counter
Summary of the Best Deal Around:

►Broad coverage 10 Hz to 26.5 GHz

►High frequency resolution 1 Hz

►High power resolution 0.1 dB

►Small size half rack, 3U

►Low cost starting from $5995
