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.

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.
