148, or ESLP 9145). The charger is Included.

The amplifier Input comes with an SMA female connector. A coaxial microwave cable of 0.5 m length is supplied to connect the Antenna with the Amplifier. The cable is equipped with N-male and SMA male connectors.

Usually, the amplifier should be installed very close to the antenna. The Amplifier Housing is equipped with rubber pads for placement on horizontal surfaces. Further, there are 22 mm holes in the housing to accept the mounting tube of Schwarzbeck-Antennas. The antenna mounting tube is usually oriented horizontally with the N-female output of the amplifier facing to ground. This avoids undesired bending of the coaxial cable.

Beginning of operation

Operation environment

The BBV 9718 is preferably used indoors. While using on open area test sites, it must be protected from weather conditions, especially humidity.

Switching ON

The device is turned on with the pilot- style power-switch. Push the switch to the upper side. The green LED “On” indicates the proper charged battery. The red LED “Low Bat” means the battery is nearly empty. If the LED is dark even while the generator is turned on the rechargeable battery is disconnected because of low voltage. After charging the unit will be ready for operation.

More Information about Battery

The BBV 9718 is equipped with a 3.7 V Lithium cell. The battery voltage is indicated with a green LED for normal operation. If the red LED “Low Bat” is illuminated recharge is required. A full battery charging period using the USB port takes around 6 hours. While recharging the yellow LED “Charge” is illuminated. The power-switch should be set to OFF during the recharging period. It is possible to measure during recharging. But disturbances generated by the charger could have an unwanted influence on the measurement. A special circuit prevents the battery from being discharged completely. Whenever the voltage is too low for battery health or measurement precision, it will be automatically disconnected from the load. When the BBV 9718 is switched ON and the red LED below is dark, this isolation has taken place. In this case the battery must be charged immediately. The second best advice is to switch OFF the BBV 9718 to avoid the (very low) idle current of the protection ci

Microwave Broadband Amplifier

Low Noise Low Power Wideband Amplifier for increasing sensitivity at fieldstrengthmeasurements and for general attenuation measurements up to 18 GHz. Due to the built-in rechargeable battery, operation without power supply is possible for ca. 8h.
