161 dBm Displayed Average Noise Level (Typ. With the Rigol DSA815-TG you can see the response, where the peaks and notches are and make the adjustments.

Frequency Range from 9 kHz up to 7.5 GHz.

The DSA815 distinguishes between signals with a frequency difference as little as 10 Hz. The all-digital IF ensures a superior and stable performance. The combination of the widescreen construction, new key layout, and feature set make this spectrum analyzer a great benchtop or field tool, with the digital power to tackle demanding production wireless applications. Mobile Offices and Transportation Equipment Try looking at it on a 10MHz span with a 10kHz RBW on both analysers and you should get a better idea of its true insertion loss.Food and Pharmaceutical Manufacturing Equipment Also, I think you need to select a much narrower span if you want to see the (narrow) cavity response properly and this applies to both analysers. Also try turning down the RBW a bit as already suggested. Features: 9 kHz to 1.5 GHz Frequency Range Typical -135 dBm Displayed Average Noise Level (DANL) -80 dBc/Hz 10 kHz offset Phase Noise Total Amplitude. You could also try the sample detector (best detector for noise) but on many analysers this can cause some subtle types of signal information to be lost if it is close to the noise floor. If the unit itself has a -40dbm noise floor then any signal lower than that will be buried in the SDRs own internal noise and even signals that may be at -30dbm may be highly degraded. In addition to the DSA-800 Spectrum Analyzer, you will need an RF Source, cabling, and adapters.

Most analysers would default to the normal detector as an all round compromise so maybe try again with this selected. Solution: This document provides step-by-step instructions on using the Rigol DSA-800 series of Spectrum Analyzers to measure the characteristics of an RF Amplifier. All our instruments support UltraSigma communication software. Explore Rigol instruments from the rugged front panel or from your PC. Many instruments also offer GPIB as well.

Control and capture data from a PC using USB or Ethernet as the bus of choice. The Rigol response looks to be about 20dB worse than this with the peak detector selected but you aren't supposed to use the peak detector to look at noise. Connect to Rigol instruments with the ease and capability of a modern computing platform. The analysers I have here typically show a noise floor a few dB lower than this with the 10dB attenuator selected. 134dBm/Hz on a 1Hz noise marker) on a typical analyser. Most analysers will have a noise figure of around 30dB with 0dB attenuation so the noise floor with a 1MHz RBW and 10dB atten selected should be about -74dBm (i.e. Rigol DSA875 9kHz-7.5GHz, -98dBc/Hz Phase Noise, 10Hz RBW Rigol DSA815 Spetrum Analyzer, 9kHz to 1.5GHz with preamplifier Rigol DSA815-TG Spectrum Analyzer, 9kHz to 1. Many analysers offer a 'normal' detector, a positive peak detector, negative peak detector and a sample detector. I think the Rigol defaults to the peak detector algorithm in the DSP so the noise floor will look very high on the Rigol unless you choose a different detector in the menus.

the model with a factory installed tracking generator, for 1495. It has many uses in the amateur workshop.

As you can see both show the peak at 150MHz but the Rigol doesn't show the negative peak afterwards (red arrow on the third picture) What do you think about? Rgds auato The Rigol DSA815-TG is a light-weight, portable spectrum analyzer that is affordable for serious experi-menters and self employed service technicians. By designing the DSA815 spectrum analyzer with a digital IF section, the variations in amplitude over time and frequency associated with analog filtering can be minimized. to select from a series of IF filters to reduce the displayed bandwidth and isolate a signal of interest from the noise floor.

10MHz to 12.5GHz -level 0dBm Of course I have just normalized the DSA815's tracking generator before. Rigol Technologies introduces its low-cost. Two spectrum analyzers are set in the same mode: -Center frequency 145MHz -Span 200MHz -Ref. The curves of the same cavity with the same cables are different.

Yesterday I tried to check the response curve of a simple 145MHz cavity filter (first picture) by two different ways: 1) by my Rigol DSA815TG scalar network integrated system 2) by HP8595E spectrum analyzer + Wiltron 6621B programmable sweep generator (two instruments run independently so they are no syncronized Wiltron generator runs faster at 10ms of sweep and HP8959E has a slow sweep at 20 seconds - see the second picture). I wish to get your attention for a strange behaviour about my Rigol DSA815TG just to know if my instrument have a trouble or I am forgotting something.
