  • PC Monitor Display Test VGA Signal Generator

    posted by svicentic

    Easy to use, just enough test screens, low power consumption, excelent pocket sized, reasonable price...
    The Unit is well designed, small dimensions, light,very easy to operate. Can be operated USB powered.Tester has just enough test screens for both CRT and LCD diagnostics. I missed even only one of wide resolutions e.g. 1366x768 or 1440x900 but you can still use built-in 4:3 resolutions to diagnose monitor fault even in full HD 1920x1080. The unit stays cool using it while testing monitor for more than 3 hours ( USB powered).
    Overall: very good unit for personal or small service use
  • It can works as jammer, no special knowledge needed.

    Thin, battery inside, led indication, two antennas and precision resistors. It's working fine, my three phones are jammed.
    No more than 10-20m working radius
    Here you can buy thing, that you need. I've search many China shops and *good known internal China market*, but there is no jammers. Now I hope more powerful and stationary jammers will be in stock.
  • Bare bones device but useful...

    It's the simplest trus GPS scrambler you can find. Other devices I tested were covering too much spectrum to be safe to use. This on covers L1 band quite cleanly.
    After mounting it in a nice metal box, replacing the power switch and finding a suitable supply, this is a nice and very cheap tool...
    Very useful in my lab to test the effectiveness and speed of GPS recovery strategies.
  • Good for this price

    This signal generator partially does what it promises. Dropped across the wireless network at all speeds (802.11b / G / N) and channels, including the 40Mhz signal from N. Knocked single mobiles operating in 850Mhz, 1800Mhz. Led keep turn on when operating.
    For this price its a great deal DIY, the best DIY deal i did last year.
    I loved it because avoid computer use at office via wireless
