A.1.4. VALIDATION PROCEDURE
1. Connect the Bantam to Minigator cable from the AM5-Classic (unit under test)
"4W SEND" to the 600 ohm load resistor.
2. Connect the AC volt meter leads to the 600 ohm resistor. See the drawing
below.
AC Voltmeter
3. Set the voltmeter to measure AC voltage.
4. Program the AM5-Classic to 4W, 600 Ohm Term and transmit 1004 Hz at
different levels. Read AC voltage on the Voltmeter and make sure readings
correspond to the values below:
Transmit 1004 Hz @
Note:
Any reading which does not fall within the above values indicates
that the unit is in need of re-calibration. Refer to the Calibration
Procedure.
