![]() ![]() The buttons have tight clearances and can rub/bind a bit if your soldering was not perfect. The plastic parts have a wavy cut edge to them like they where cut free hand on the short ends. I purchased this as a guest so I apparently cant leave a review. You're best advised to use a magnifying glass while working on the switches and check for solder bridges (that seem to form quite easily on the switch terminals). The pins are small and very close together. However, if you find yourself mesmerized by the low price, be sure to read the assembly instructions over three or four times before soldering anything in place.Īlso, make sure you have a very thin point soldering iron and high-gauge solder. I realize this is my own fault for not reading the assembly instructions as closely as I needed to before soldering down those switches. Also, isn't there some other part that will do the same function as these push buttons that is polarized and not possible to put in backwards? This is an epic design fail these parts might be okay for a production line, but not for one-off kits. But something important like this needs a MUCH bigger warning. I realize the engineer who wrote the assembly instructions is probably not a native speaker. Ever tried to unsolder 300 pins? Well, let's just say I'm not even going to try, I'm just throwing the board away and will resume looking for a decent function generator. Sadly, I soldered in around 25 switches, luck would have all but about 5 were backwards. However, there is an "Important Notice" about the switches that is NOT in line with the assembly instructions warning you that the push button switches only go in one way. I started putting it together following the instructions as best I could. I really don't know if the thing works well or not. I came across this kit and figured "gee, if it's only $50 bucks, what can go wrong?" My instincts told me, don't buy it, my greediness won out. I was evaluating various hobby-level function generators in the $250-$500 price range. This kit reminds me of the saying "Buy once, cry once". It can even be used as an adjustable DC voltage source by setting the amplitude to 0. The FG805 can generate a peak to peak amplitude up to 10V with an offset range from -5 to +5VDC. The incremental step size can even be adjusted to make sweeps over a wide range easier to handle. Frequency, amplitude and offsets can all be set with the number pad and incrementally adjusted with the rotary encoder. The LCD screen and menu system make this an easy instrument to operate. Three different operating modes allow the FG085 to generate 7 different types of continuous waveform as well as servo test and control signals in micro-second resolution. ![]() Just solder the through-hole parts in place, attach the face/base plates and before you know it you'll be generating sinewaves at frequencies up to 200KHz! But that's only one of the tricks this thing can do. The FG085 MiniDDS Function Generator is a 'some assembly required' kit that becomes a flexible, functional and easy to use frequency generator. Quotations for RF signal generators made via everything RF are directed to the manufacturer or their distributors based on your geographical region.Function generators are useful in a ton of applications from RF to embedded logic. Once you narrow down on the signal generator based on these key parameters, you can compare matching products, download datasheets, see details product specification or request a quotation. A value in the power range can usually be set using the control panel or a computer interface. Power Range: This is the amplitude of the signal that is generated. This is usually 1, however multi-channels signal generators are also available. The lower the phase noise the better.Ĭhannels: This is the number of simultaneous output signals that can be generated from the signal generator. Phase Noise: This parameter can be used to identify the spectral purity of the signal generated. Vector Signal Generators can generate signals that vary in both amplitude and phase.įrequency: This is the frequency range up to which or in which the RF signal generator can generate signals.įrequency Resolution: This is the level by which the frequency can be increased or decreased. Analog Signal Generators, also known as Signal Sources or Frequency Synthesizers are those generators that can generate a signal at a desired frequency range that varies in amplitude. This is the first and one of the most important filters. Type: Analog Signal Generator or Vector Signal Generator. ![]()
