Tel: 886.909 602 109 Email: sales@salukitec.com www.salukitec.com Chapter 3 Analysis on Common Faults 3.1 Lighting failure of power indicator lamp Fault cause: The keyboard has fault or the CPU board has communication fault. Instrument to be repaired: Digital display megawatt multimeter FLUKE 1508. Repair method: 1. Check whether the DC voltage output by the adapter is 14 V - 16 V; 2. If the adapter is normal, firstly replace the front cover assembly; 3.

If the frequency accuracy significantly changes, it shall be determined that 100 MHz reference ring has fault, and the IF channel plate shall be replaced. 3. Please replace the frequency synthesis board if the fault still exists. 3.5 No signal detected when the pan smaller than 5MHz, but normal when the span is larger than 10MHz Fault cause: The frequency synthesis board has output fault.
Tel: 886.909 602 109 Email: sales@salukitec.com www.salukitec.com oscillator phase noise index deviation, and the frequency synthesis board shall be replaced. 3.9 Abnormal attenuation control Fault cause: The attenuator has communication fault. Instrument to be repaired: Synthetic signal generator S1465H. Repair method: 1. Check if the communication cable of the attenuator is properly fixed and the metal clip is normally installed . 2.
