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
IMPORTANT
•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.
Test 1: Measurement of a 10 MHz Digital Pulse and Its Radiated Emissions
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.

7. Set the N9912A FieldFox RF Analyzer to operate in the Spectrum Analyzer mode. Select the
start and stop frequencies, and other settings according to the following configuration:
Mode : SA (Spectrum Analyzer)
Start Frequency : 10 MHz
Stop Frequency : 400 MHz
8. Connect the EMC probe (H-field Probe) to the RF In port of the N9912A FieldFox RF Analyzer
using an RF coaxial cable.
9. Switch S1 and S2 to the ‘ON’ position to power on the Digital Pulse Output and Digital Buffer
sections.
10. Place the EMC probe on top of the digital buffer trace that is being tested. Slowly move the
EMC probe around the trace and observe the spectrum displayed on the screen of the
N9912A FieldFox RF Analyzer. Describe your observation.
11. Switch S1 and S2 to the ‘OFF’ position, and turn off the power supply.

Test 2: Measurement of the 10 MHz Sine Wave Output in the Presence of Motor Noise
Figure 2 –Experimental Setup for the Measurement of a 10 MHz Sine-wave Output in the
Presence of Motor Noise
1. Supply a 5 V input voltage to the EMI Source Module.
2. Switch S5 to the ‘ON’ position to turn on the 10 MHz Sine Wave Oscillator.
3. Use a digital oscilloscope to probe test point TP11 with respect to GND, which is the output of
the 10 MHz Sine Wave Oscillator. You should observe a pure sinusoidal waveform.
4. Next, switch S4 to the ‘ON’ position to turn on the brushed DC motor. Observe the output of
the Sine Wave Oscillator in the presence of motor noise. Describe the differences as
compared to the observations made in Step 3.
5. Switch S4 and S5 to the ‘OFF’ position.
6. Connect the output of the 10 MHz Sine Wave Oscillator (J8) to the RF In port of the N9912A
FieldFox RF Analyzer using an RF coaxial cable.
7. Power on the N9912A FieldFox RF Analyzer.
8. Set the N9912A FieldFox RF Analyzer to operate in the Spectrum Analyzer mode. Select the
start and stop frequencies, and other settings according to the following configuration:
Mode : SA
Start Frequency : 5 MHz
Stop Frequency : 15 MHz
N9912A Setting: “[ ]”: Hardkey; “{ }”: Softkey
Set Mode to SA measurement: [Mode] > {SA}
Set Start Frequency to 5 MHz: [Freq/Dist] > {Start} > [5] > {MHz}
Set Stop Frequency to 15 MHz: [Freq/Dist] > {Stop} > [15] > {MHz}
Set output power level to LOW: [Meas Setup 4] > {Output Power} > {Low}
Scale: [Scale/Amptd] > {Autoscale}

9. Switch S5 to the ‘ON’ position to turn on the 10 MHz Sine Wave Oscillator. Observe the
spectrum of the sinusoidal signal.
10. Next, Switch S4 to the ‘ON’ position to turn on the brushed DC motor. Observe the spectrum
and describe the differences as compared to your observations in Step 9.
11. Switch S4 and S5 to the ‘OFF’ position, and turn off the power supply.
