How to reduce or lower noise floor? (DSA815 and DSA1030) Last Updated: 01/08/2014 A simple sequence of settings will help you dig into the noise floor. With any Spectrum Analyser, setting up the (1) Span, (2) Attenuator, (3) Pre-amp and (4) Resolution Bandwidth settings - these are all important starting points to getting the best noise floor. Remember, safety first (no input or power RF nearby)...

Remember, safety first (no input or power RF nearby) and try adjusting these four settings to find out more about what to turn on, and o...

How do radio amateurs use RIGOL’s DSA815? And for what kinds of applications?

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Some simple examples of useful Radio Club application: An FM Broadcast Station was causing interference to our 2m to 4m transverter. This corresponded to an FM station which was recently launched. There were no problems before this Broadcast station went live: "We were able to identify all of the transverter RX output signals (wanted and spurious)" On the DSA815-TG the tracking generator can be us...

What about RIGOL battery and portable use? Can you run RIGOL Scopes and Spectrum Analysers from Battery or portable UPS Power Supplies?

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Running the DSA815 from a battery (see also comment about other instruments) Although the size and weight of the DSA800's make it attractive for use in locations where there is no power, it suffers from the lack of an internal battery. A Google search uncovers a raft of battery backed up power supplies but the recommendation is that the DSA800's run from a supply that has a sine output. For thi...

USB stick / flash drive / memory sticks must fully compliant with USB2.0* standard compliant w/Win7 – Info on good sticks, esp. earlier models:

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
We have found many instruments to be fussy about USB sticks (more common on instruments of slightly longer-standing design). Like PictBridge standard, USB memory specs can be quite open to interpretation and may vary between manufacturers. Please try the following guidelines if you are having difficulty - it is especially important you can rely on the stick you have chosen, if you decide to do ...
