I will save you a ton of frustration: the OUT connector on the coupler goes to the TG output.
#Dsa815 firmware how to
Took me a bit to figure out how to connect this to the SA. For this you will need something called a directional coupler (I can recommend the Mini Circuits 15542 ZFDC-20-5 BNC Directional Coupler) with 20dbm attenuation. The coming week will start off with antenna testing, the main reason I got the SA for. Found one BNC T-connector that was flakey within minutes.
#Dsa815 firmware Patch
Next I measured the loss of all of my patch cables and connectors. The first thing I did was use this as the world's most expensive FM radio.how? Just attach any short antenna to the input jack, turn on the DEMOD (FM) function, plug in earbuds/headset and set the frequency range to about 90-120 mhz.
You will also need an assortment of N adapters, patch cables, T connectors, etc. 1-2W will be ok for most passive measurements, but if you want to hook up any transceiver you better do your math well. They must be of the DC-1500mhz (or higher) variety. So you MUST get a set of attenuators (called pads) to go with this. It can be damaged very is NOT like a scope! 100mW (+20dbm) is the max you can feed into the input. First off let me say that you must be extremely careful in what/how you connect something.anything to this device.
#Dsa815 firmware generator
I got the TG model as I often heard that the tracking generator option is well worth the extra cost, and I must agree. In this case Rigol is good, but Siglent is much better.įirst let me state I had zero experience with a spectrum analyzer (SA). Do the research and I think you will agree. They make some really good stuff and I own a bunch of it! But the Siglent spectrum analyzer wins hands down as to performance. Please understand that I absolutely dont hate Rigol. So back it went, because the reality of the test numbers are not subject to opinion. But once the “wow” factor wore off, and after a friend brought his Siglent SA over for some back to back testing, I realized what a REAL spectrum analyzer could do. I reluctantly returned this unit after playing with it for several days. The equivalent Siglent product is between 12 and 18 db more sensitive, has a radically better noise floor, and only costs about $250 more. Yes, you can sweep an antenna with it (very nice, if you get the tracking generator option which is a mandatory option IMHO!) and you can easily see what mischief is coming out of your transceiver/amp in realtime, but the basic design of this unit is simply a bit flawed. But that being said, this spectrum analyzer just isnt a favorite of mine. In light of fact, I have a 4-channel Rigol scope, 3 channel Rigol programmable power supply, Rigol bench multimeter (6-1/2 digit), and a Rigol arbitrary waveform generator. They make quality test equipment at an amazingly low price. Let me begin by saying this is a good (not great) value for the money.
