6.0 Operation
Page 7
To operate the DA-1G plug the AC power cord into an appropriate AC power outlet. The
DC power cable may also be connected to an appropriate DC power supply.
DC power may be used as a main power source for the instrument or in conjunction with
the AC power as a backup power supply in case of loss of the main AC power. The
instrument is designed to automatically switch from AC to DC power supply to ensure
uninterrupted continuous operation.
Once AC power is supplied to the DA-1G, the LED on the front panel labeled AC POWER
will turn on. If you also applied DC voltage, the LED labeled DC POWER will also turn on.
The DA-1G is designed to distribute signals from 700MHz to 1100 MHz. The RF input has
a 50-ohm input impedance. Provide a signal within the mentioned frequency range to the
SMA connector on the back panel labeled INPUT. If the RF signal has a power level
greater than +7 dBm, the monitor LED located on the front panel will light up.
Twelve buffered copies of the RF signal provided will be available on the SMA connectors
located on the back panel labeled OUTPUTS.
