SP-05-1 EXCITER ACTIVATED IN TELEPHONY MODE
The exciter output frequency is set to fTX = 22000.0 kHz, LF signal generator can be connected to testbox
terminal AF to Telex, and the handset key is valid. Mode shift is possible, but the modulation is turned
off in H3E mode. Exciter step attenuator is set to max. output power.
SP-05-2 TEST OF EXCITER STEP ATTENUATOR
The exciter output frequency is set to fTX = 22000.0 kHz, and the step attenuator is incremented with 1
step every 700 uS, until step 63 is reached. Then the attenuator is reset to step 0.
The test programme is used in the performance check, section 3.5.3.4., module performance check,
section 3.6.4.6., and module adjustment, section 3.7.3.6.
SP-05-3 TEST OF EXCITER 70 MHz FILTER
This test programme is used in the module performance check, section 3.6.4.7., and in module
adjustment, section 3.7.3.7., where it sets up the synthesizer and exciter to control the 70 MHz
intermediate filter.
SP-05-4 EXCITER ACTIVATED IN TELEPHONY MODE
The exciter is activated as in test programme SP-05-1, but the exciter output frequency is changed to
28000.0 kHz.
SP-05-5 EXCITER ACTIVATED IN TELEPHONY MODE
The exciter is activated as in test programme SP-05-1, but the exciter output frequency is changed to
14900.0 kHz.
SP-05-6 EXCITER ACTIVATED IN TELEPHONY MODE
The exciter is activated as in test programme SP-05-1, but the exciter output frequency is changed to
1600.0 kHz and modulation is possible in H3E mode
