Rigol Spectrum Analyzer Dsa815 Tg5/1/2021
The DSA815TG fits the bill perfectly for my homebrew activities.Add a Rigol VSWR Bridge and youd have the additional capability of measuring input or output return loss (e.g.Impedance matching and antenna tuning).
Rigol Spectrum Analyzer Dsa815 Tg Series Spectrum AnalysersThe Rigol DSA800 series spectrum analysers have several other options available to enhance the capability and user experience even further. The N type to other coaxial connectors was useful Having two N to BNC adaptors would have helped me. Id been quoted silly prices for second hand units at well over twice the price of the Rigol and with much lower spec. This unit does everything I want of it and I couldnt say fairer than that. Scan rate (DSA815-TG) about 1 per second over full (1.5Ghz range) scales up if you reduce the scan range. Thats at default setting can be slowed down a lot if you mess about with RBW and VBW but at its price point its fine. Quasi-Peak detection makes it so slow its unusable. Maybe on its 7500 big sister thats proportional but not on the 1400 815. The display resolution is excellent and I have not found any spurious responses either, across the full spectrum. Very easy to use. The TG performance is good with very little ripple or roll off across the full spectrum. In the zero span mode you can use the TG as a RF signal generator. The format is wrong in places i.e. Front panel controls section, it describes the REAR panel USB socket Ordering and delivery was a pleasure with helpful staff at Telonic and delivery in a 1 hour slot, next day, by DPDs Interlink service. Is easy to use and the function keys give quick access to setting the required trace. I have been using it to check harmonic frequencies of frequency standards and test the effectiveness of some analog filters. Very happy with the service and quick response of Telonic Instruments who supplied the unit and also made sure that it had the latest firmware installed. One day the wolf came knocking at my door and the DSA had to go, well i say wolf i really mean Wife. First order arrived at 14:30 and the second order, two days later tried to deliver mid morning which was unexpected and I was not at home. A delivery service with timed tracking as offered by other couriers would avoid missed deliveries However, a great service with keen pricing. Cant be beaten for the price gives the more expensive stuff a run for its money which is less the typical Agilent repair cost. However the power sweep does not work, this is disappointing in a new instrument. The forums report this is a Firmware issue, I hope it can be resolved in the next revision.
