NOTE
Radio button will not fill if entry fell outside the TI's
acceptance window. (The Instructions/Messages box of the
TS-4530A RF Calibration Utility program displays a failed
limit check.) If this happens, fill it by clicking on it. This will
be necessary to perform prior to clicking SAVE TO UUT.
NOTE
Checking a parameter immediately after adjustment will
return the same measurement result as before the adjustment.
For the on screen measurement to reflect the adjustment and
for the new coefficient to be saved to the TI nonvolatile
memory, click SAVE TO UUT to update the coefficient in the
TI. Unplug and re-plug power cord into J106 and press S3.
Avoid excessive power interruption (This moves coefficients
into TI non-volatile memory).
Select CONNECTION
CONTROL tab and click Rescan Ports. (Rescanning ports will
allow retrieval of newly stored coefficients inside TI without
rebooting the program and waiting the 5 to 20 minutes for TI to
GET FROM UUT to update instrument controller. Final
logged coefficient displayed in the Instruction/Message box at
completion of adjustment will be displayed as the TI's initial
coefficients. Re-checking the parameter will display the result
of the new calibration coefficient. This process may be done at
the end of each adjustment or once at the end of the procedure.
12. Receiver Power Calibration
CAUTION
Do not apply greater than +43 dBm (20 W) to the DIRECT
port or greater than +10 dBm to W3 (A5J1) or W4 (A5J2) or
equipment damage may result.
a. Performance Check
(1) Connect RF reference source leveling head output to TI coax cable W4 (A5J2).
(2) Set RF reference source to 1030 MHz at +5 dBm and output to STBY.
(3) On the instrument controller, click command button 1030 RX SUM followed by
command button OK to close the dialog box.
(4) When prompted, set RF reference source output to ON.
(5) TI will indicate +5.00 dBm 1.5 dB. If TI indication is within tolerance, click
command button OK. Radio button will fill indicating that parameter is complete. If TI
indication is not +5.00 dBm 1.5 dB, perform b below.
(6) Set RF reference source output to STBY.
