3.5.3.2 PERFORMANCE CHECK OF EXCITER FREQUENCIES AND CLASSES
OF EMISSION
1. If only this section is performed, please start by carrying out the section 3.5.3.1. point 1, 2, and 3.
2. Select test programme SP-05-6 (fTX = 1.600 kHz).
3. Set the testbox switch RF ON/OFF on.
4. Adjust the LF signal generator to an output of 1Vpp (0.35V
RMS
) and a frequency of 1600 Hz.
5. Adjust the oscilloscope gain until full deflection (8 div.) is seen on the screen.
6. Toggle the MODE switch on RE2100 between J3E, R3E, H3E, and TELEX, and control that the
deflection is approx. the same in all the classes of emission 8.0 +/-1.0 div.
7. Disconnect the LF signal generator.
8. Select the emission mode H3E on RE2100 and control that the deflection seen on the oscilloscope
is 4.6 +/-0.5 div.
9. Select the emission mode R3E on RE2100 and control that the deflection seen on the oscilloscope
is 1.2 +/-0.2 div.
10. Select test programme SP-05-4 (fTX = 28.000 MHz).
11. Select the emission mode H3E on RE2100.
