I'm thinking about using another signal generator to perform the measurement. All I can really say, is that my distant rejection of my filter (which would block the image frequency) is better than 100dB. This mathematically subtracts a reference signal (stored automatically) from the input signal. 6) Normalize the reference insertion loss. Now, clear the trace, turn off the TG, and do it again. Figure 4: Reference cable insertion loss before normalization. Let it run for a bit with the power average.

Turn on the preamp, your narrowest RBW (10Hz in my case). Noise floor/Dynamic range: When the tracking gen is running, the minimum value I can get out of the noise floor is -94dBm. If I turn the normalization back off (and accept the 4dB or uncertainty) it works as expected. I should be able to move the reference trace (in the ampt menu) up or down. Then, everything should behave as normal.

I would expect that when I normalize the TG, it should have a trace at 0 dBm (which I should be able to change in the normalize menu, and can). Chapter 5 Specifications RIGOL Specifications for DSA800 Series 7 Trigger Trigger Trigger Source Free run, Video, External External Trigger Level 5 V TTL level Tracking Generator (DSA815 Option) TG Output Frequency Range 9 kHz to 1. Buggy amplitude menu: Only happens when you are working with a normalized TG output. I've narrowed it down to the tracking generator, in both counts. It should be about -79dBm in a 1MHz bandwidth if it was corrected. However this noise level isn't 'corrected' (eg the nature of the log detector will affect the displayed noise level) and the true noise level will be a little bit higher. If the RBW is set to 1MHz and the sample detector is selected then the noise averages at just under -80dBm on the display. This is based on the spec sheet so the actual result could be a bit different BY contrast, my HP8566B shows a noise floor of -139dBm/Hz at 145MHz with the 10dB attenuator selected and the (corrected) 1Hz noise marker function. If the 1Hz noise marker function was activated it should auto switch across to the 'sample' detector and if a bit of averaging is switched in then I'd expect the noise marker to show a noise floor of about -125dBm/Hz with the 10dB attenuator selected. So this could make the trace hover around -57dBm on a wide span. But the default detector is the peak detector and if the VBW is also up at 1MHz then this will lift the trace up by several dB. So the noise floor with a 1MHz RBW should be about -65dBm. Looking at the specs the noise figure with the 10dB attenuator inline is about 49dB. A Preamplifier is standard on all models in the family.Yes, it does look very high. In addition, Rigol offers great options including an EMI filter and quasi-peak detector kit, VSWR measurement package, and tracking generator (“-TG” version) for all of these models. The DSA832, DSA832E, and DSA875 have a DANL (displayed average noise level) down to -161 dBm (typical). The DSA815 distinguishes between signals with a frequency difference as little as 10 Hz.

The spectrum analyser offers the ability to measure smaller signals using our digital IF filter, which allows for smaller bandwidth settings and reduces displayed noise levels. The DSA800 family features a widescreen display, compact design, and easy-to-use interface making it ideal for benchtop or field apps in RF and wireless testing and production. Rigol’s DSA800 Series spectrum analysers redefine the product category by setting new standards for performance and price.
