The 4240 series is a CW RF power meter designed for high-speed production testing and benchtop use, offering measurement ranges from -70 dBm to +44 dBm depending on the sensor, with a 90 dB dynamic range and five-digit resolution. It supports single or dual-channel operation, with measurement rates of 200 readings per second for one channel and 100 for two. The instrument features a backlit LCD displaying numeric and bar graph data for both channels simultaneously, and includes IEEE-488 GPIB and RS-232 interfaces with SCPI command compatibility. It emulates HP437, HP438, 4220A, and 4230A models and accepts Boonton diode, thermocouple, and waveguide sensors from 10 kHz to 40 GHz. The device includes an automatic calibration function using a built-in 50.025 MHz calibrator and operates from 90 to 264 VAC. The instrument is housed in a chassis measuring 8.26 by 3.48 by 13.5 inches and weighs 5 pounds.
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.
