The Sark-110 is a great bang-for-buck deal at US$360 with registered airmail delivery and compared to similar units it rated very well in the designer's comparison list. Read the manual (which is available on-line only) to see all the features!
Ordered from "Seeed Studio" and it arrived 1 week later. First impression: surprisingly small ... about the size of a mobile phone and just as thin. Gorgeous colour TFT screen! I'm in two minds about the MCX to BNC-f Test Port cable, but it will take stress off the tiny MCX connector and the calibration process includes the short cable so it will not effect the readings/accuracy.
After heeding the missing step in the instructions (see the Sark-110 Google group thread https://groups.google.com/forum/?fromgroups=#!topic/sark110/Tu3JxcqKiF8 ) I updated to the latest firmware version which made some functionality and display improvements, and added a raft of additional features. Even better!
The ability to store screen shots as .bmp image files is nice, but the plots can also be saved to .csv format and then displayed on a PC via an Excel chart with software like Zplots http://www.ac6la.com/zplots.html ... now that is just brilliant.
Hints: When ordering from Seeed Studio, also buy the Mini-USB cable if you don't have one. It is required for charging the Sark-110 battery (from a laptop USB port) as well as updating the firmware, and retrieving screen saves or the .csv data files. http://www.seeedstudio.com/depot/mini-usb-cable-100cm-p-252.html?cPath=178_179
Also consider the "Digital probe for DSO Quad" item with a view to replacing the two probes with crocodile clips for connecting to a Yagi feedpoint. http://www.seeedstudio.com/depot/digital-probe-for-dso-quad-p-849.html?cPath=178_180
Since it arrived it has been used extensively for antenna work, building LP filters, and sweeping ferrites to make choke baluns.
Happy as a sand boy!
