To remove CPU

1 Remove cover (see ‘’To remove cover’’).

2 Using a T-10 torx driver, remove the nine screws from the A7 CPU assembly. Lift the assembly up, unpluging the A7 CPU assembly from the A8 Memory assembly and A99 Motherboard.

3 Disconnect the ribbon cables from the A7 CPU assembly.

4 The analyzer’s serial number and firmware options are stored in EEPROM (U27) on the A7 CPU assembly. Before replacing the CPU assembly, remove A7 U27 from the faulty assembly and insert into the new assembly. See ‘’What to do before replacing the CPU assembly’’ on page 6-3.

used in two channel analyzers. The A12 BNC assembly routes the signals connected to the Channel 1 BNC connector and Channel 2 BNC connector to the A1 Input assembly. The A12 BNC assembly also routes the source signal from the A5 Analog assembly to the Source BNC connector. The signal connected to Channel 1 should be between 0.19531 Hz to 102.4 kHz in single channel mode and between 0.097656 Hz to 51.2 kHz in two channel mode. The signal connected to Channel 2 should be between 0.097656 to 51.2 kHz. For both channels, the signal’s amplitude range must be between +27 dBVrms and –51dBVrms for full scale measurements. The source output signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine.
