1. Quick Setup and Verification

1.1
Basic Setup and Test Procedure for the ME1400 Training Kit
The following steps demonstrate a basic setup and test procedure using the ME1400 training kit:
Test 1: Measurement of a 10 MHz Digital Pulse and Its Radiated Emissions
Test 2: Measurement of a 10 MHz Sine Wave Output in the Presence of Motor Noise
The training kit can be damaged by excessive power levels from instruments. Please adhere
strictly to the power levels recommended in the instructions.
Turn off the training kit when not in use.

Figure 1 – Experimental Setup for the Measurement of a 10 MHz Digital Pulse
1. Supply a 5 V input voltage to the EMI Source Module.
2. Switch S1 to the 'ON' position to power up the 10 MHz Digital Pulse source.
3. Use a digital oscilloscope to probe test point TP3 with respect to GND. You should observe a
10 MHz digital pulse. Measure the rise time of the digital pulse.
4. Switch S1 to the 'OFF' position.
5. Connect an RF coaxial cable from J2 (Medium-speed Output) to J6 (Digital Buffer with
Termination with No GND Plane) as shown in Figure 1.
6. Power on the N9912A FieldFox RF Analyzer.
