Like have an expensive W7ZOI analyzer but withīuilt in CRT and a bit wider in coverage. Using cheap ceramicįilters to acheive rbw. Voltage to indicate center freqency on display. Still I would love a modern light weight version of the HP 8566/8, sameĪs for the cheaper ATTEN spectrum analyzers they all seems to be nicely With rbw >10kHz, expensive at 2,5k yes but hopefully this shows what canīe done in near future by others (read Asia) Now the Signal Hound has a game changer the BB60A real time spectrumĪnalyzer, it can record 20 MHz bandwith and has a scanning of 24 GHz/sec

Still both instruments are neat, and I am sure they both can do Looking at sweep times for the Rigol it sure is no speedĭeamon either, when going for narrow resolution bandwith. It do some internal band switching around 150 MHz which can add So if you need close up sweeps it isįaster, and may be anoyingly slow with high resolution and larger Sweep time is due to how they designed the analyzer, it has a 250 kHzīand with and then step this. And frequency coveragae is 0-4.4 GHz which may come in handy. One of the neat features of the SH is it is powered through USB and hasĪ very small foot print! I am amazed on how good the performance is vs. The Rigol was not available when I made my decision so it was down to There are plenty of SHs in use and people like them my decision for the Rigol was just a personal one. I imagine that, in this mode, the SH only samples at or near integer multiples of the fundamental, thus saving a lot of time by not sampling data between the harmonics.

The answer was to speed-up the sweep time. I joined the SH Yahoo Group when I was shopping one question I asked was why the Harmonic mode existed. There's not much real difference between 270 ms and 10 ms in use but sweep times get much longer as you "home-in" for more detail if the difference remains in proportion it might be 270 seconds -v- 10 seconds and that is substantial.

Just for interest I set my Rigol to the same span & RBW and it sweeps in 10 ms. It seems to sweep much more slowly than the DSA-815 for instance the SH spec for a span of 10 MHz and a RBW of 100 kHz is 270 ms in Fast Sweep mode. > The problem I see with the Signal Hound is the sweep width.Īs far as I know the Signal Hound can be set to any sweep width. There's also the possibility of using a tracking generator.

The HP 70000 series SA may be faster than the 4395A and has a higher upper frequency limit. The ultimate SA for me is the HP 4395 Network - Spectrum - Impedance Analyzer with true 1 Hz RBW and true RMS detection

The NRD-545 receiver can be used as a spectrum analyzer with the addition of a computer and NRD free software.ġ0 Hz IF bandwidth because of DSP If processing. If one instrument has the high stability option use it as the source for the others.Īnother option is to use a GPS Disciplined Oscillator as the source: Most HP equipment has both an input and output for the reference frequency so you can just daisy chain them. The Signal Hound ran a close second though a good instrument I think. My decision on a SA came-down to the Rigol or the Signal Hound I decided that I prefer a stand-alone instrument that operates conventionally so I chose the Rigol. The DSA should be OK for two-tone SSB testing I have done amplifier IP3 tests with good results Here it is displaying two signals about 500 Hz apart The strength of the DSA-815 is in its RBW which goes down to 100 Hz whilst this is not as good as the 1 Hz minimum RBW found in high-end SAs (which can cost as much as a good car) it's a very good spec for the price and makes the DSA very useful for the average experimenter.
