switching caused by poor contact or DC voltage instability (equivalent to AC)
could possibly damage the pre-stage of the apparatus.
For different REF, the power resistance of the apparatus varies. With a
relatively low REF, 13dBm is enough to cause damage (this value should be
considered as 0dBm below 1MHz). Note that this value is total power level,
not just the observed signal.
(5) Under circumstances where there is risk or the risk is unclear,
protection measures like DC blocking, attenuation and filtering should be
adopted. Last but not least, set the reference level to maximum(20dBm)
before connecting the circuit that is to be tested.
5.Operation Manual
KC908 can be described as versatile. And the design principle for the
menu is to be clear in steps and logic, but not the simpler the better. To live
up to this principle, our designers have optimized the human-computer
interaction logic with the aim of making it possible for the users to educate
themselves following intuition solely. It would typically take half an hour for a
person with basic RF knowledge to get the hang of KC908.
One thing we take for granted is that KC908's users are all professional,
thus the main focus is the counter-intuitive part. As for the menu structure,
the more concise way is operating in person.
