1. Q: Can I use the Tracking Generator on the Rigol DSA 832 spectrum analyser as a fixed RF Source?
A: Yes. Many spectrum analysers, like the Rigol DSA800 series, have tracking generator options available .The tracking generator is an RF source that follows the frequency sweep settings of the spectrum analyser. Please see the Rigol Application note titled “How to use the tracking generator on a Spectrum Analyzer as an RF Source” under the documents tab of the Rigol DSA 832A-TG.
2. Q: I’ve turned the Rigol DSA 832A-TG on and it’s a bit sluggish. Why is this?
A: The Rigol DSA832A and Rigol DSA800 series has an auto cal feature on it. The unit will perform auto calibration within half an hour of being booted up and then every 10 minutes after that. Instructions for turning this feature off can be found in the manual. Some customers find it useful to have auto Cal enables when the unit first boots up and then manually perform calibration as required. The choice is yours.
3. Q: How do I retrieve trace data from the Rigol DSA815, Rigol DSA832 or the Rigol DSA 875 spectrum analyser?
A: You can do this using the Ultra Sigma Software. If you have not already done so you’ll need to download the software to your unit. If you need help or instructions please give us a call. More information can be found under documents tab. The application note is titled “Data Collection from the DSA800 spectrum analyzer with Ultra Sigma.”
4. Q: How does the Rigol DSA 832 detect overload?
A: The hardware circuit detects the power, if it exceeds the limit an alarm sounds.The overload detection/protection is performed at the first input stage before the attenuator. If you hear the alarm it’s extremely important that you stop what you are doing otherwise you could overload your unit. It's dangerous for the DSA . You should not solely depend on the built in protection. It’s recommended that you use something like a transient limiter when working with any spectrum analyzer. These can be purchased from Instruments 4 Engineers.
5. Q: What is a transient limiter?
A: The transient limiter protects the spectrum analyzer input from damage caused by high-level transients.
6. Q: I want to measure VSWR. How can I do that with a Rigol Spectrum Analyser?
A: You would need to buy a unit with the tracking generator option and the VSWR option for the spectrum analyser. Please see the application note titled “Measuring VSWR with a Rigol Spectrum Analyser “under the documents tab.
