美國無線通信集團(tuán)（Wireless Telecom Group；NYSE: WTT）旗下Boonton公司近日推出4240系列功率計(jì)，該系列功率計(jì)是經(jīng)典的Boonton 4230系列功率計(jì)升級版。產(chǎn)品完全向后兼容，并可與現(xiàn)有Boonton CW二極管和熱電偶傳感器配合使用。4240系列功率計(jì)所支持的測量單位有：dBm、瓦（watts）、dBr以及V（電壓，備選）。
產(chǎn)品特點(diǎn)
4240系列有單通道（4241）和雙通道（4242）兩款選擇。兩款儀表均帶有集成校準(zhǔn)器，可提供超穩(wěn)定、50MHz參考信號，校準(zhǔn)功率范圍為-60dBm至+20dBm，功率測量結(jié)果以5位數(shù)或者條碼圖進(jìn)行LCD顯示。
4240系列支持-70dBm至+44dBm的RF功率測量，最大動態(tài)范圍為90dB（具體取決于傳感器）。進(jìn)行RF功率測量時(shí)的頻率范圍為10kHz至40GHz，進(jìn)行電壓測量（備選）時(shí)的頻率范圍為10Hz至1.2GHz。測量速度為每秒200次（4241）或者100次（4242）讀數(shù)。
4241/4242功率計(jì)采用SCPI指令集或Lab VIEW驅(qū)動軟件，可與自動測量設(shè)備（ATE）系統(tǒng)進(jìn)行簡單集成。另外，4240系列兼容HP437、HP438以及先前的Boonton 4220A/4230A功率計(jì)，可以通過標(biāo)準(zhǔn)的RS-232或者IEEE-488接口進(jìn)行遙控。
The 4240 series power meters are the successors of the well known Boonton 4230 series. The new 4240 is fully backwards compatible and can be paired with all available Boonton CW diode and Thermocouple sensors.
The 4240 series is offered as one channel (4241) or two channel (4242) instrument. Both meters come with an integrated calibrator that provides an ultra-stable, 50-MHz reference signal, and deliver a calibration power range from -60dBm to +20dBm. A built-in calibrator allows sensor calibrations right before the measurement providing highest measurement accuracy. Power measurements are displayed with five-digit resolution or bar graph.
“Boonton’s power meters are utilized in countless educational, military and manufacturing applications. The new Boonton 4240 series follows our tradition providing flexible, reliable, state-of-the-art test equipment,” said Wolfgang Damm, director of product management at Wireless Telecom Group. “With its built-in compatibility to all current and legacy CW sensors, Boonton 4240 series protects customer’s past and future investments.”
4240 series allows RF power measurements from -70dBm to + 44dBm with a maximum dynamic range of 90dB (sensor dependent). The frequency range is 10kHz to 40GHz for RF power measurements, and 10Hz to 1.2GHz for voltage measurements (optional). Supported measurement units are dBm, watts, dBr and volts (optional). Rapid display update rates allow convenient operation with tuning applications. The measurement speed of the 4240 series is 200 / 100 (4241/4242) readings per second.
SCPI command set or available Lab VIEW® drivers for both the 4241 and 4242 power meters allow simple integration in automatic test equipment (ATE) systems. Furthermore, the 4240 series emulates HP437, HP438 and legacy Boonton 4220A / 4230A meters. Both the 4241 and 4242 instruments can be remote controlled via standard RS-232 or IEEE-488 interfaces.
