4240 RF Power Meter



The 4240 series of CW RF power meters provides the high speed measurement capability needed in a production environment, as well as the simplicity of operation required for bench top use. It provides very accurate measurements from -70 dBm to +44 dBm (sensor dependent) and has a rapid display update rate for tuning applications. The easy to read LCD displays both channels simultaneously with numeric and bar graph information.

  • -70 dBm to +44 dBm, depending on sensor
  • 90 dB dynamic range, depending on sensor
  • 10 kHz to 40 Ghz measurement range
  • Single or dual-channel display
  • >200 measurements per second
  • Agilent HP 437 & Agilent HP 438,  and Boonton 4220A & 4230A emulation
  • Automatically loads sensor data
  • Simple software control via SCPI language
  • 50 MHz step calibrator
  • IEEE-488 and RS-232 interfaces standard

Principles of RF Power Measurement

A primer on RF and Microwave Power measurements

RF Power measurement techniques have evolved considerably since the earliest days of wireless. “Principles of RF Power Measurements” provides the reader an in depth guide to key methodologies for measuring CW, average and peak RF power signals using thermistor, diode detector, RF receiver-based, direct RF sampling, and monolithic IC techniques.
