Mini Circuits ZFDC-20-5) allows for very accurate antenna measurements, there are excellent videos about this on Youtube.īear in mind the SA is an extremely sensitive RF measuring device, therefore the use of a good set of attenuators is highly recommended to protect the front end from overloading (it can handle 30dBm - 1W/50V DC), you will have to do your math especially when counting on paring it directly with a high output RF device (e.g transceiver IMD measurement). The build in FM/AM demodulator allows monitoring of the local broadcast stations, just plug in some earbuds or external speakers :-) I also added some adapters to adapt from N to BNC or SMA. I have added a screen protector (better safe than sorry), a mini usb key to store measurement screenshots and bought a weatherproof carrying box (B&W type 6000) for safe transportation. Operation of the unit is very easy, the layout of the front panel is intuitive and the large color display is really a big asset. I personally also use it to verify/tune the cavities of the 144MHz and 433MHz analog repeater setup of the local HAM radio club. For fun, I measured the loss of all my cables in the shack and quickly identified at least one that had issues. There are plenty of use cases such as testing filters, coax cables, connectors and lots of other stuff in the shack. I hooked it up to my LAN and external 10Mhz GPSDO reference. Siglent provides firmware updates which are a breeze to apply. I chose the Siglent over the Rigol DSA815 for its better noice floor (-161 dBbm/Hz), phase noise, slightly larger screen (10.1 inch) and higher resolution (1024圆00).įor as far as I can determine this, the firmware of the device seems to be mature, I have not yet come across any major bugs or flaws and the layout of the menu structure is well thought through. There is an extensive thread over on Eevblog discussing this subject. Tracking Generator) including extending the usable range up to 3.2 GHz. I have owned the Siglent SSA3021X for half a year and overall I am very pleased with it.Īlthough by no means cheap, it is a modern and affordable bench/transportable instrument covering 9KHz up to 2.1GHz out of the box with 1Hz RBW! The unit can be easily 'software upgraded' to enable all on-board functionality (e.g.
