Test Setup
6.1.3
Meters
Output voltage can be monitored at TP7 with a voltmeter. Input current into the load must be monitored
with an appropriate ammeter. Transmitter input current and voltage can be monitored also but the meter
must use averaging function for reducing error due to communications packets.
with an appropriate ammeter. Transmitter input current and voltage can be monitored also but the meter
must use averaging function for reducing error due to communications packets.
6.1.4
Loads
A single load is required for 5 V with a maximum current of 1 A. The load can be resistive or electronic.
6.1.5
Oscilloscope
A multichannel oscilloscope with appropriate probes is used to observe the RECT voltage at TP12 and
other signals.
