Keysight U1620A 2 channel 200 MHz handheld scope. I bought it as having a broken channel 2 but it works perfect. Added a pair of Tektronix THP0301 300 MHz probes.
With both channels is works nicely to 240 MHz before any aliasing, with a single channel its 3 dB point is 360 MHz - not bad at all.
Would be nice to have more history on this guy. The earlier handheld Agilent scopes were made in Korea by Escort I do believe. This scope is made in Malaysia and runs WinCE 5.0. It has the typical stainless steel torx screws and the boards internally are Agilent branded. It also uses the same lithium battery packs as the Keysight FieldFox line of handheld RF analyzers. The GUI is very responsive but the software feels like it could be further optimized.
I don't have the proper power adapter which is 15 VDC @ 4amp. It uses what I am calling a 2.5mm "safety" barrel plug - does anyone know where to source one, I have plenty of power adapters and would be happy to just change the end.
Attached are a few pics looking at a 1 MHz 1 Vpp signal from an AWG, don't try probing like this at home kids!
