For more information see eevblog here. The signal is low current when the unit is on around 32uA which is well below the uA limit for such gear.
AC current leaks through this capacitor to the DC output connectors. From my perspective this is unacceptable for electronic test equipment as it could easily damage whatever it is connected to if that equipment is earth referenced.
It arrived today and I did a quick head-to-head comparison between it and my Rigol DG signal generator. The FYS lets you control the waveform either from your computer using software and a standard USB A-B cable or via a front panel with 2-line LCD display, several membrane buttons and a rotary encoder dial.
Interaction is straightforward, but clunky compared to the Rigol. Unfortunately the USB cable does not power the generator. You must power the generator via its 2-conductor AC cable universal 85vvac. I usually comment on the reports and expect them to be fully professional when you are ready with part 2. Your grade will be a G, a short for Good in Swedish. For higher respect you need not only to do what you are asked, but also to do what you want, meaning that you come up with your own ideas.
If you hear a lot of wows and ahas then you know you are on the right track. How else are we to create good industry leaders? Is to develop your creative talents and to teach what is being useful to others. I want you to lead, too, and not only follow. I hope that this course mirrors at least some of the professional world out there in which you will have to follow the rules, but also shape your own. We all do what is expected of us G , but Creativity is this extra spice VG.
By not only knowing how to play the ball, but also leading the team, I hope you will be more twice as attractive. Good team leaders and visionaries are hard to find. In the first course is to get going with serial communication, a crucial knowledge necessary in any computer system.
Is almost like a meeting with your customer who wants a reliable products and easy to follow manual. The computer you have created is your fair examiner.
Are very important but even more so if you take a distance course. Read data sheets, application notes, source code and ask questions about things you do not understand. Use e-mail, call me, and ask me questions on seminars. Do not be afraid to ask. My job is to explain. Your job is to learn. Later, when you work as a designer, then you are always on your own.
So, you will have to develop a way of getting to the point with the help of the tools of the trade: data sheets, your brains, experiments and general knowledge. Thanks to all who helped me, Bill.

If someone has the software for the FYS family, please could you share it? Sincerely yours, bobofrut. Quote from: bobofrut on April 27, , pm. Pages: [ 1 ] Go Up. To switch from one channel to another, press the buttons to the right of the BNC connectors. A second press of these buttons switches the channel off.
The only shortcoming of this counter is that there is no sensitivity control and the counter only responds if you apply at least 2 V peak-to-peak to this input. What does the FYS deliver? An impressive number of fixed signals: - Sine. In addition to these periodic signals, you can program two sweep signals, one with a linear sweep and the other with a logarithmic sweep. You can program the start, end and sweep time. In this case, either the frequency or the amplitude changes from one value to another by an external control signal.
Finally, you can of course set the value of all signals up to 20 V peak-to-peak, but you can also control the DC offset, duty cycle and phase difference between the signals on CH1 and CH2. Save and Load functions The FYS offers twenty memory locations, in which you can save the settings of a channel for later use.
Operation of the generator A front panel with nine 'push buttons' and a rotary encoder are available for operating the unit. And that is the great weakness of this device. When you press in such a place, you do not press the underlying push button, but move the device backwards. You can only operate the FYS by pressing the top of the device firmly with your hand and pressing the buttons with your thumb.
What do you get for your money? Unfortunately, the power cable comes only with an American plug. The FYS is delivered with an extensive cable set. The circuitry of the generator itself is completely mounted on a large PCB that is mounted behind the front panel. As is clear from the picture below, no attention has been paid to shielding, so the generator will undoubtedly be a nice radiation source on your work table.
All internal connections are made with single, unshielded wires, including those to the two TTL-outputs on the back. The case is made entirely of plastics.
