37、er Supply The DPM uses a rechargeable Nickel-Metal Hydride battery pack. Charge life is a minimum of 100 hours continuous usage. “Low Bat” is displayed when the batteries require charging. ?NOTE: For optimum battery life, charge the batteries only after “Low Bat” is displayed. The DPM can use an ext

38、ernal power source. Using the DPM with the ac adapter or the 12V cigarette lighter adapter will also charge the battery. Charging time from full discharge is 8 hours using the ac adapter. When using the cigarette lighter adapter, charge time will depend on the car battery charge. ? AC Mains Adapter

39、To use the ac adapter. insert the adapters barrel connector into the DPMs external dc connector (See Figure 2 on page 2). Insert the adapter plug into a wall receptacle. ? Automobile Cigarette Lighter Adapter Insert the adapters barrel connector into the DPMs external dc connector. Insert the adapte

40、r plug into a cigarette lighter jack. CAUTION Use a Bird adapter only and do not use the adapter with the batteries removed. Bird Model 5000 Digital Power Meter 10 Figure 4 DPM Connections Installation 11 DPM Connection Although unlikely, it is possible to corrupt the power sensor firmware by connec

41、ting it to the DPM while the DPM is on. To prevent this, always turn the DPM off before connecting or disconnecting a sensor. Connect the power sensor to the “Sensor” port on the DPM using the sensor cable provided. If you are using the optional PCTool software, connect the PCs serial port to the “R

42、S-232” port on the DPM. RF Connections Directional Power Sensor (DPS) Connect the DPS to the RF line so that the arrow on the DPS points towards the load. The element in the forward socket should be inserted with its arrow pointing in the direction of forward power, as shown below. The reflected ele

43、ment should point in the direction of reverse power. The forward elements power rating must be 10 x the reverse elements rating. CAUTION Always turn off the DPM before connecting or disconnecting a sensor. WARNING Never attempt to connect or disconnect RF equipment from the transmission line while R

44、F power is being applied. Leaking RF energy is a potential health hazard. Bird Model 5000 Digital Power Meter 12 Terminating Power Sensor (TPS) RF connections are the same for the TPS-EF and the TPS. In most cases, the TPS should be connected to an attenuator or a directional coupler. For example, t

45、o measure a transmitter with power output between 0.1 and 50 Watts, use a 40 dB, 50 Watt attenuator. Insert the attenuator between the TPS and the RF source. Only connect the TPS directly to the source if the RF power will be less than 10 mW. Figure 5 DPS Element Orientation CAUTION Ground all instr

46、uments before connecting the TPS(-EF). Electric shock could damage the sensor. CAUTION When connecting the TPS or the TPS-EF, only turn the connector nut. Damage may occur if torque is applied to the sensor body. CAUTION Do not exceed 2 W average or 125 W peak power for 5 s when using the TPS or the

47、 TPS-EF. Doing so will render the sensor inoperative. 13 Chapter 3Operation The Bird Digital Power Meter is very easy to operate. Once a sensor is connected, turn the DPM on and take a reading. Additional commands are available, depending on the sensor used. Normal Operation ? Connect the sensor. ?

48、Turn on the DPM. ? Set the measurement units by pressing FWD Units and RFL Units. ? If you know the system loss or are using an attenuator, add the losses (in dB) of all components in the system. For attenuators and other frequency- dependent components, use the loss at the measured frequency. Then,

49、 press OFFSET and enter the total loss in dB. This will allow you to read the actual line power. The DPM accepts offsets from 0 to 100 dB. ? Turn on the RF source. ? Read the power level on the display. ?NOTE: The analog bar graph will respond immedi- ately to changes in the RF power. The major and minor displays will respond after a delay of 1 to 13 seconds, depending on the power level.
