The DA-500 is a general purpose isolation amplifier designed to distribute frequencies from 100 to 600 MHz. This Amplifier offers 80 dB of channel-to-channel isolation and 85 dB of reverse isolation at 500 MHz. The low phase-noise, (-130 dBc/Hz at 1 Hz and -160 dBc/Hz at 10 KHz) ensures that the distributed signals are not degraded.
The outputs have a low VSWR, typically 1.2 (return loss of 20 dB), to minimize environmental effects on frequency distribution through long transmission lines. There are two inputs (SIGNAL A and B) each driving six outputs.The instrument is equipped with power level monitors that compare output power levels to a preset threshold of +7dBm. If the signal on any output drops below this threshold, the monitor LED located on the front panel and corresponding to either SIGNAL A or B, will turn off indicating a fault condition.
The inputs and outputs are chassis grounded. The standard unit has two inputs and twelve outputs. The DA-500 operates on 100 to 240 VAC, and is offered in a stand-alone rack-mount enclosure with dimensions of 1U X 19” X 14”.
