and i've used this unit very seldomly within this past 8-9 months, not the 100% everyday use business. so i think something inside is really fragile to damage. i hope the repair will involve making the circuit more immune to damage and more robust, we dont want next time 2-3 months after warranty period, the unit will be damaged again. after warranty, this is difficult and costly for repair. 10 days ago
i already sent back my unit for repair under warranty yesterday. from our email, Deepace indicated this is hardware issue and provided me with address to send back my unit. Hope they will repair soon. I got charged $89 by DHL duh.
For info. I've never connected my unit to any serious active device or any Vdc. I'm aware of the input safety to avoid overloading and damage. and i've tried many settings including system recalibration, but i still cant get back the 0dBm on RF Source output. The only active device connected is a China ADF4355 Signal Generator powered from 5V USB power supply, that i bought separately to learn mixer with KC901V and Advantest R3465. Now my KC901V is broken, i have to wait for repair before i can continue learning and designing RF circuit again. 10 days ago
HI. PLEASE IGNORE THIS THREAD THIS IS A FALSE REPORT. MY HI AND LO LO MODE IS OK. I THOUGHT HI MODE WILL BE INDICATED NEAR BUTTON MENU (WHITE BACKGROUND) BUT HI AND LO LO MODE IS INDICATED JUST UNDER THE GRAPH PLOT. SO ITS MY MISTAKE. THERE IS NO PROBLEM WITH MY HI/LO LO MODE. sorry i have to use capital letter since there is no formatting available in this forum to highlight my point and this flat view forum make it difficult to see the latest comment. Cheers. 10 days ago
