Review of ALPINE ASG-301 AM/FM Signal Generator 

Since I couldn't find any information about this model on the Internet, I created an overview of this signal generator.
It got a bit long. You can skip to the key parts here:
1:40 - Outside overview
4:00 - Inside view (top cover removed)
5:48 - Power on and functions review (sorry for audio, overloaded my mic :S)
14:43 - Testing with frequency counters (using an TTi TF930 & Systron Donner 6153)
16:57 - Output power test (R&S USB power sensor)
22:29 - Output signal spectrum (R&S FSP series Spectrum analyzer)
26:16 - Connecting an antenna and tuning the radio to it
Maybe anyone knows what does this label @ 0:58 "AM noise limit sensitivity low" may mean?
Also if it's manufactured exclusively under Alpine trademark. What's the original manufacturer/model/designer? On the backside @ 1:54 there's amall ABO Co. Ltd. Made in Japan label. The same label also was seen on front panel PCB @ 5:24
Thanks for watching my video.
