PROCEDURE
Checking the power supply LEDs
• Power up the IDR IDO 3G with the mains or a DC source (according to the type of
primary convertor).
• Set the “I/O” switch (see Plate 6.IV, item 2 or9) on the primary convertor to “I”.
• For the primary mains convertor (item 1):
- Check that the “AC” (item 5) and “DC” (item 4) LEDs are lit.
• For the primary DC convertor (item 6):
- Check that the “PWR IN” (item 8) and “PWR OUT” (item 11) LEDs are lit.
- Check that the "FAULT" LED (item 7) is out.
If there is a problem, refer to Sheet A-3.
Antenna output test (SWR and transmission power output)
• Connect the power meter power sensor between the "ANT" socket (see Plate 6.II,
item 15) and the antenna cable, using the torque wrench.
• Power up the power meter.
• Set the “I/O” switch (see Plate 6.IV, item 2 or9) on the primary convertor to “I”.
• Select a IDR IDO 3G channel (see Section 3.4.2).
• Select the 1.5 W transmission power level (see Section 3.4.3).
• Enable transmission (see Section 3.4.4).
• Check that the yellow TX LED of the 3G PA-TRX is lit (see Figure 2.1, item 10).
• Check that the green TX LED on the duplexer is lit (see Figure 2.2, item 6).
If there is a problem, refer to Sheet A-6.
• Check that the SWR and transmission power are correct (see Table 4.9).
• Repeat the test with a transmission power level of 4 W, 10 W and 15 W.
• Record the values in a table similar to Table 4.9.
• Enable transmission (see Section 3.4.4).
• Set the “I/O” switch (see Plate 6.IV, item 2 or9) on the primary convertor to “O”.
• Disconnect the power meter.
