Advantest R3465 Manual Test setup and calibration must be performed at both the TX and RX frequencies. Table B-24: Procedure for Calibrating Test Cable Setup Using Advantest R3465 Step Action * IMPORTANT – This procedure can only be performed after test equipment has been allowed to warm–up and stabilize for a minimum of 60 minutes.
Manual Cable Calibration – continued Table B-24: Procedure for Calibrating Test Cable Setup Using Advantest R3465 Step 16 Action B Disconnect the power meter sensor from the R3561L RF OUT jack. * IMPORTANT The Power Meter sensor’s lower limit is –30 dBm. Thus, only components having losses < 30 dB should be measured using this method. For best accuracy, always re–zero the power meter before connecting the power sensor to the component being calibrated.

Downloading ROM Code Exception Procedure – Downloading ROM Code This procedure is not part of a normal optimization. Perform this procedure only on an exception basis when no alternative exists to load a BTS device with the correct version of ROM code. C NOTE One GLI must be INS_ACT (bright green) before ROM code can be downloaded to non–GLI devices. CAUTION The correct ROM and RAM codes for the software release used on the BSS must be loaded into BTS devices.
Downloading ROM Code – continued CAUTION The Release level of the ROM code to be downloaded must be the one specified for the software release installed in the BSS. The release level of the ROM code resident in the other devices in the BTS must also be correct for the BSS software release being used. ROM code must not be downloaded to a frame loaded with code for a BSS software release with which it is not compatible. C This procedure should only be used to upgrade replacement devices for a BTS.
Downloading ROM Code – continued Table C-1: Download ROM and RAM Code to Devices Step Action 8 Double–click the Code folder. – A list of ROM and RAM code files will be displayed. 9 ! CAUTION A ROM code file with the correct HW Bin Type must be chosen. Using a file with the wrong HW Bin Type can result in unpredictable operation and damage to the device. Click on the ROM code file with the filename which matches the device type and HW Bin Type number noted in step 3 (for example, file bbx_rom.bin.
