Except for AM, it is better than the competitors in almost all characteristics. AM is not brilliant, but OK, signal quality is very good, and the vector version works from 5MHz upwards. These are OK except for the (list) price. The bigger one, the DSG3030 is better in this respect, but stay away from the vector version because of an unclean modulator and an IQ carrier lower frequency limit of 50MHz.
This one works OK except for massive clipping in AM at higher modulation depths. Real connoisseurs buy a Keysight PSG or a premium Rohde & Schwarz. RIGOL DSG815 series are OK with restrictions, RIGOL DSG3030, or Keysight EXG or MXG are more expensive but have better characteristics. One, better two RF Signal GeneratorsĬovering the frequency range of interest. Surprisingly, even brand new Anritsu hardware is everything but bug free.

I also tried an Anritsu MS2036A, a fine piece of hardware but the slow speed and unstable PC connectivity drives me nuts. Even the predecessor looked the same except for the floppy disk drive 🙂 and Windows XP. This boatanchor has been on the market with almost no changes for a decade now, so the bugs are (mostly) gone. Dynamic range suffers a bit a higher frequencies, but for hobby use this box is absolutely OK.

1K€), and an ingenious hack using minimal hardware and a lot of software tricks to obtain the frequency range. Filthy rich people buy a Rohde and Schwarz ZVA, a Keysight PNA-X or an Anritsu VectorStar.Ĭheap (ca. Poor people buy a DG8SAQ VNA3, in case of superfluous funds a Keysight E5063A or, even better, an E5071C is great.

It can be partially replaced by a spectrum analyzer with tracking generator if you are facing budget constraints. This is swiss knife number two for the RF engineer.

I also tried an Anritsu MS2036A (VNA plus spectrum analyzer), a fine piece of hardware but the slow speed, unergonomic software and unstable PC connectivity drives me nuts.

The most important part is the external preamp with this one it outclasses pro machines costing three times the price. A lot of options make no sense (e.g., the phase noise app is so insensitive that it can only measure above -110dBc, and a lot of wireless protocol apps are of no use in amateur radio). Not really cheap, and you need an external preamp and some apps (noise figure, demodulation, external source control, direct IF output, enhanced display, internal preamp) on top of it. One of the best selling budget analyzers. Filthy rich people buy a Rohde and Schwarz FSW or even an FSWP, or a Keysight PSA or UXA. Poor people buy a RIGOL DSA815TG, if you can buy a Keysight CXA or better. This is the swiss knife of the RF engineer. (with tracking generator if you do not have a VNA). Equipment needed for RF DevelopmentĪ well equiped RF workbench needs the following test equipment: A Spectrum Analyzer The suggestions I give are from my personal experience only they are not based on any kind of market research.
Funny enough, I like equipment that has survived on the market for 10 years or more a lot better than brand new stuff with spectacular user interfaces combined with a lot of bugs and quirks. This pro equipment need not be the latest generation old or used equipment is absolutely OK if it is working fine and is properly calibrated. So if you are able to invest a little bit of money, I suggest to get some pro equipment to start from. While making test equipment by yourself can be rewarding, saving costs and providing learning possibilities, in RF it is extremely difficult to create precision equipment without the help of precision equipment. Understanding and especially making test equipment can be a highly instructive and fascinating task, because it involves a lot of understanding of the underlying physical principles and mathematics, plus some really sophisticated and elegant electronics design techniques. Its like the boy scouts: the main issue is that one must be prepared to test just in case the need arises.
Test Equipment can become an obsession of its own right, even if there are no devices that need to be tested.
