Test Equipment Oscilloscopes

Among all test equipment that a ham radio operator should be capable to use, one has ever attracted the curiosity of many of us: the Oscilloscope.

The Oscilloscope is something that should not miss from any serious repairing desk and is also something that you really need if you want to start your electronic measurements.

Generally speaking the usage of this particular devices can vary from case to case and needs,  and can be applied to several different scenarios.

In our hobby, hams can use an oscilloscope as an RF Signal Monitor, usefull to observe the RF envelope from your transceiver.

You can check  quality of transmission your transceiver is really sending out.

Inside DXZone

Here on DXZone we are collecting many links about  Oscilloscope .

Shopping and Services
http://www.dxzone.com/catalog/Shopping_and_Services/Test_equipment/Oscilloscope/

You can start from our Test Equipment shopping category where you can locate places to buy oscilloscopes. You can certainly find a local electronic dealer near your home that can properly indicate the best oscilloscope for your needs.

Manufacturers
http://www.dxzone.com/catalog/Manufacturers/Test_Equipment/Oscilloscope/
Here you can find all links to most popular Oscilloscope manufacturers including Agilent, Hameg, Iwatsu and many others including those makers that since some years are now taking advantage of PC based solutions to produce PC-Based oscilloscopes.

Software
http://www.dxzone.com/catalog/Software/Oscilloscope/
As stated before, now you can use your own pc to transform it into a powerfull oscilloscope.
Oscilloscope software programs are capable to convert a PC into a dual-trace storage oscilloscope and spectrum analyzer. Typically they uses your computer’s sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal. These programs can also work as audio spectrum analyzers for real-time, FFT, as Frequency counter, as voltmeter, noise and distortion meters, or phase shift meters.

Technical Reference

A tribute to Marconi

Marconi Guglielmo The 25th of April is the birthday anniversary of Guglielmo Marconi, born in Italy on 25th April 1874.

Marconi is for most of europeans considered the father of Radio, but as we know the Italian iventor was not the first to invent Radio, since many other scientists reached this goal, but he can be considered the Pinoeer of DX (long distance contact) since he demonstrated how to provide intercontinental telegraph transmissions using the radiowave propagation.

Tokyo hy-power files for bankruptcy

A popular ham radio products manufacturer leave the market

Tokyo Hy-Power, world famous Japanes amateur radio equipment manufacturer filed for bankruptcy on 24th December 2013.

Tokyo Hy-Power, founded by JA1DJW Nobuki Wakabayashi, since 1975 has been an industry leader in military, medical, commercial and amateur product market, and is particularly famous in the ham radio market for their HF and VHF RF power amplifiers.

Several news about Tokyo Hy-Power bankruptcy  has been published on the net during last days,  and major regional dealers are already taking actions, including HRO that announced  is already working to assure technical support and replacement parts in the US marked for the Japanese products.

Japanese web site has been taken down and is no more available,  while the US site is still responding.
