2.3 OPERATING F REQUENCIES VS ICAO CHANNEL DESIGNATORS
For all test frequencies listed in test setups in this report, the ICAO Channel Identification developed for the 8.33 kHz channels is used. The channel identification will not necessarily reflect the actual operating frequency. Table 4.7-1 shows the relationship between ICAO Channel Identification, actual operating frequency, receiver bandwidth, and ARINC 429 frequency control word. NOTE: Narrow Band (NB) is selectivity for
8.33 kHz channels and Wide Band (WB) is selectivity for 25 kHz channels.

5.3 STANDARD ARI NC 429 BUS/DATA CONFIGURATIONS
5.3.1 Standard Control Data Configurations
5.3.1.1 VHF-4000
All test steps are performed using continuous tuning on the low speed ARINC 429 control bus 429_Input_Port_B (Pins 3 and 4). The control words are labels 030 for 25 kHz channels & 047 for 8.3 kHz channels.
Calibration and TFM parameters are set using the high-speed maintenance input bus MAINT_IN (Pins 9 and 10) and output port MAINT_OUT (Pins 13 and 14). The control word is label 277 (See Appendix for format).
5.3.1.2 VDL-2000
All test steps are performed using continuous tuning on the high-speed ARINC 429 maintenance input bus 429MAINT_IN (pins 1 and 32). The control words are labels 030 for 25 kHz channels & 047 for 8.3 kHz channel s .
Calibration and TFM parameters are also set using the high-speed ARINC 429 maintenance input bus 429MAINT_IN (pins 1 and 32). The control word is label 277 (See Appendix for format).
5.3.2 Standard Data Configurations
• The “Standard 25 kHz ARINC Configuration” is defined as follows:
Octal label 047 (8.33 kHz label) s et to NCD. Transmit the control data on label 030 (Oct) every 200 ms. The tuning channel will be defined at the time of reference to this definition.
The SSM is set to 11 (squelch disabled). SDI set to 00 (All call).
• The “Standard 8.33 kHz ARINC Configuration” is defined as follows:
Octal label 030 (25 kHz la bel) set to NCD. Transmit the control data on label 047 (Oct) every 200 ms. The tuning channel will be defined at the time of reference to this definition.
The SSM is set to 11 (squelch disabled). SDI set to 00 (All call).
5.4 TEST SEQUENCE
If the UUT has never been aligned then all alignment steps must be performed in sequence. For re­alignment of UUT as a result of a repair action or modification, perform only alignment steps of circuits that have been effected by repair action or modification. Checksum will be automatically updated whenever FLASH memory is updated.

6. Alignment
Connect main connector plug from test station to UUT. Apply 27.5 ± 0.5 Vdc to the power input.
VHF-4000, power pins 58, 64 and ground pins 59, 65. VDL-2000, power pins 10, 11 and ground pins 8, 9.
Wait 30 seconds for the unit to complete power on testing.
The VHF4000 or VDL2000 may be aligned per Section 6.3 Alignment Procedures or with the automatic alignment system (CATS-21) executing DGS-005.
6.1 SOFTWARE LOAD PROCEDURE
Load the desired top-level software using the data loader capability of the VHF-4000 or the boundary scan interface.
6.2 CALIBRATION AND TFM PARAMETERS
The VHF-4000 uses electronic alignment for circuits that use values for various parameters stored in FLASH memory. TFM parameters are those that require different values depending upon temperature, frequency or mode. Calibration parameters are those that are the same for all temperature, frequency, and mode.
6.2.1 Initialization of Calibration Parameters
Store into FLASH memory the hex values for calibration parameters listed in the following table or the nominal value (nominal values derived from trend data).
