Using the HAMlab Diagnostic Accessories Pack is easy. First, connect the oscilloscope probes to the relevant ports on your HAMlab for accurate signal measurement. Then, attach the adapters and termination connectors as needed for different types of testing. When using the spectrum analyzer, signal generator, bode analyzer, or logic analyzer, just follow the on - screen prompts. For the logic analyzer, remember it has an extra fee. As for maintenance, keep the accessories clean and dry. Avoid exposing them to extreme temperatures or moisture. If you notice any damage, stop using the part immediately and contact customer service for replacement.
