Page 5: Introduction
The inputs and outputs are chassis grounded. The DA-1G is designed to be powered by a 100 to 240 VAC mains source or by a +12 to +36 VDC for instruments acquired with the DC power option. If both AC and DC sources are powering the instrument, the DC source will be used as backup power in case of AC power outages. -
Page 6: Safety And Preparation For Use
2.0 Safety and Preparation for Use The DA-1G was designed for indoor use only and is not intended for operation outdoors or in a wet environment. The instrument may be mounted in a standard 19-inch instrumentation rack or may be used on a laboratory bench. -
Page 7: Instrument
DC disconnect means for the instrument. 2.2 Instrument Safety and Preparation for Use The DA-1G is designed to distribute RF signals with a frequency of 700 to 1100 MHz. Output levels below +7 dBm will trigger a fault condition which can be monitored from the front panel. -
Page 8: Front Panel Description
The monitor LED will be on if all RF outputs are greater than +7 dBm. RF signal levels less than +7 dBm will trigger a fault condition and the Monitor LED will not light up. However the DA-1G will still provide twelve buffered copies of the RF input signal. Page 4... -

If the DC Power option is installed, this instrument may also operate on DC power from +12 to +36 VDC as the main power supply. When the DA-1G is set up to operate with both AC and DC power sources at the same time the DC power is used as backup power in case of AC power outages. -
Page 10: Installation
The instrument may be mounted in a standard 19-inch instrument rack or may be operated on a laboratory bench. Connecting Power The DA-1G ships with a standard North American, European, or Chinese IEC power cord. Locate the AC POWER entry module on the rear of the enclosure and connect the power cord. -
