VERIFICATION FAILURE: If any step in this procedure fails or is out of tolerance,
this indicates a failure in the Test Set. Refer to
Troubleshooting for corrective action.
STEP PROCEDURE
1. Make the coax connections as shown in Figure 22.1.
2. Press the SETUP button until the SETUP-TIS screen is displayed.
3. On the SETUP-TIS screen, set up the UUT as follows:
RF PORT: ANTENNA
ANT RANGE: 12 ft
ANT HEIGHT: 1 ft
UUT ADDRESS: MANUAL
MANUAL AA: A92492
4. Press the TCAS button twice to display the TIS screen
5. Set the RF Generator to –10 dBm @ 1090 MHz, external pulse modulation.
6. Connect the computer COMM port to the RS-232 connector on the Break out
Box.
7. Using the Tera Term terminal program, send the ‘MTL_Disable’ file, found on the
IFR 6000 maintenance manual CD, to the UUT to override the MTL function of
the unit. Press the LOCAL Soft Key to return the UUT back to local mode.
8. Connect ARB #2 to the computer USB port and start the Intuilink software. Send
the file, “TIS.wvf”, found on the IFR 6000 maintenance manual CD to ARB #2
volatile memory. Enter the required Frequency and Output voltage when
prompted as:
Function ARB #1 ARB #2
Frequency 1kHz 15.625kHz
Output Pulse, 5Vpp, 0V Offset Arbitrary, 5V high, 0V
Trigger External, positive slope External, negative slope
Mode Burst, 1 cycle Burst, 1 cycle
Impedance High Z 50 Ohm
9. Verify ARB #1 and ARB #2 are set according to table 25.1.
10. Set the pulse width on ARB #1 to 132.75µS.
11. Press the RUN TEST Soft Key.
