La serie Boonton 4540 son instrumentos que se seleccionan para la captura, despliege y analisis de potencia de RF en el dominio del tiempo y de la estadistica. Las aplicaciones incluyen señales pulsadas de RF como las de radar, TDMA, GSM, señales pseudo aleatorias o parecidas a ruido como las señales de CDMA, WLAN y WiMAX. La serie 4540 puede ser de uno (4541) o dos canales (4542) de RF. El medidor puede medir señales moduladas o CW (portadoras) usando sensores Boonton de pico (Peak) o de promedio (Averange). El rango de la amplitud y frecuencia es determinado por el sensor que se usa. La serie 4540 tiene tres modos de operacion: Pulso, Estadistico y Modulado/CW. Algunas caracteristicas incluyen: | |
| • | Alto ancho de banda y gran rango dinamico de los sensores |
| • | Interface intuitiva |
| • | Pantalla de color de 4” |
| • | Resolución de tiempo de 200 psec |
| • | Analisis estadistico, incluyendo CCDF |
| • | Visualizacion de texto de 15 mediciones de tiempo y potencia |
| por canal | |
| • | GPIB, USB y LAN |
