Test Procedure
•
After 5 seconds verify that:
•
Transmitter—Status LED D5 should be green flashing ~ 1 sec
•
You should hear a beep from the transmitter
•
Transmitter—LED D2 still ON
•
Receiver—LED D1 is ON
•
UUT—Verify that Vout is 4.9 V to 5.2 V ( Between J3 or TP7 and J4)
•
UUT—Verify that rectified voltage should be 5 V to 5.4 V (between TP3 and GND) (Note: a modulation
signal is present on this voltage every 250 ms and may cause fluctuation in the reading use lower
value or base line)
6.4.4
Efficiency Test (500-mA Load)
•
Verify that input current to TX is less than 260 mA with input voltage at 19 VDC
•
Turn OFF Transmitter Power Supply (19 V)
6.4.5
Operation (1-mA Load)
•
Turn ON Transmitter power supply (19 V)
•
Transmitter—Verify LED D2 is “ON”
•
UUT—Adjust load current to 1 mA ±200 µA
•
Put the receiver EVM on the Transmitter coil and align them correctly
•
After 5 seconds verify that:
•
Transmitter—Status LED D5 should be green flashing ~ 1 sec.
•
You should hear a beep from the transmitter
•
Transmitter—LED D2 still ON
•
Receiver—LED D1 is ON
•
UUT—Verify that Vout is 4.9 V to 5.2 V ( Between J3 and J4)
•
UUT—Verify that rectified voltage should be 6.6 V to 8.6 V (between TP3 and GND) (Note: a
modulation signal is present on this voltage every 250 ms and may cause fluctuation in the reading use
lower value or base line)
6.4.6
Efficiency Test (1-mA Load)
•
Verify that input current to TX is less than 80 mA with input voltage at 19 VDC
•
Turn OFF Transmitter Power Supply (19 V)
6.4.7
PMA Test (1000-mA Load)
•
Turn ON PMA Transmitter power supply(18 V) or by using the adapter that comes with the PMA
transmitter
•
Put the receiver EVM on the Transmitter coil and align them correctly
•
After 5 seconds verify that:
1. You should hear a beep from the transmitter
2. Receiver—LED D3 is ON
•
UUT—Adjust load current to 1000 mA ±50 mA
•
UUT—Verify that Vout is 4.9 V to 5.2 V ( Between J3 and J4)
•
UUT—Verify that rectified voltage should be 5 V to 5.4 V (between TP3 and GND) (Note: a modulation
signal is present on this voltage every 250 ms and may cause fluctuation in the reading use lower
value or base line)
