1.5Ghz seems rather low for a VNA these days.
Is there a 3.2 and or 6Ghz version as well?

Rohde&Schwarz do not think so.
Just ago launched new FPC1500  Spectrum  & VNA base model is 1GHz.
The FPC1500 can be upgraded up to 3GHz VNA included

Yes of course. As I told BASE model is 1GHz. You buy it and then you buy things what you need. More os less handfull of options. Even VNA is option what need pay separately.

But still base model is 1GHz and my message only purpose was just answer for quy who wonder this Siglent "low" 1.5GHz limit. What is still more than R&S  base  model of FPC1500.
Not for start debate about R&S features and option. Only for show that even 1GHz comprabale equipment is lauched by A+ grade manufacturer just ago. No one is there to ask if it's a bit low just in the current years. As we can see name is important.

I drive a LEC (low el. consumption) BEV car. Smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

Wises must compel the mad barbarians to stop their crimes against humanity. Where have the wises gone?

not looking for debate either :)
for me the main point is not the bandwidth but the single port instead.
we will learn more in the short future.

The did, as their base/educational model, their mainstream gear is very...very..different in regards to both SA and VNA performance/freq. range and of course, target market.

As far as I know, Transcat does most of the Siglent Calibrations in the US and unfortunately I don't think the CALIBRATION CERT's come cheap.

Siglent is going to be at the IMS2018 conference next week in Philadelphia with the SVA1015X.  After speaking with one of the rep's yesterday, I believe that it will also have mod/demod software options too.  I just hope it has QAM-256 to QAM1024 modulation upgrades with MER, preBER and postBER capabilities.

I went fishing for a release date today only to be told the same as last week: June.

Estimated price around 1500$


hmm i have to preorder one, if the price is real. From what i see, SSA1015X is at 9980 RMB (1400EUR) and SVA1015X at 36780 RMB (4800EUR) -> http://www.siglent.com/spectrum_analyzer/SVA1000X

Correct.
China price for SSA3021X is the same.  ;)

I would be interested to know how much the SVA1000X differs from the SSA3000X *HARDWARE WISE*.

Is it really a new hardware or could everything VNA related (in theory) been implemented by software?

Regards,
Vitor

An informal poll:

If you are an SSA3000X owner, would you rather have purchased this if it were also available at the time of your purchase?

This a all off the cuff, but it might be theoretically possible to use the SSA hardware (with caveats) - as only one of the LO's is actually sweeping, and that same LO is downconverted and used to generate the TG output. I don't think the hardware is the same though.

Therefore the phase relationship - after power up - between all of the PLL's - might not change between the TG output and the SA input as it sweeps (assuming nothing is altered). Since the LO1 which is sweeping the TG is also used to downconvert the input, the phase of that doesn't need to be consistent.

To do an OSL VNA measurement you at a minimum need to be able to do four sweeps where the phase doesn't change. One for the open, one for the short, one for the load, and one for the measurement. The problem arises if you reset or preset the SSA, then all of the PLL's will come back up at different phases and so your calibration needs to be done again.

The other caveat is that there is only one input, so there can be no reference measurement. This means that any drift will directly impact the measurement.
Real VNA's have at least two receivers - one is used as a reference - and the DUT measurement is compared against the reference measurement.

As a point of comparison the Signalhound products cannot maintain the phase relationship between the SA and the TG as they sweep - because they are physically  different devices and only share a 10MHz reference, but don't share the same LO. They can make VNA type measurements at a single frequency (i.e. no sweeping) but the system only has only one receiver and so they have the drift problem above.

This could all be worked around somewhat using a solid state switch to provide a reference input and a DUT input and switch between them as needed to measure and correct for the phase issue on each frequency change, and it would also allow a correction for most of the drift issue. However the isolation of the switch would be an issue that would affect the measurement at some point and would need to be corrected for.

Possibly, although I would miss the up to 3Ghz range.

It should be possible to divide down the source output and feed it into a phase detector. As long as the frequency and phase are known the REF receiver shouldn't be necessary for basic 2-port measurements since the REF can be constructed from the DDS parameters, time, VCO phase detection, and cal data.  But, the devil is in the details and we ARE talking "measurement grade" quantitative correctness here, not a curve that "mostly looks awrite"...

Yep - would upgrade if they had a 3GHz version. Hopefully that will follow.

SVA1015X is the top model in this series in which there is also a China market only model SSA1010X-C of 1 GHz capability.
I know of nothing else in development but it would seem to me the next step would be into higher frequency models based on the experience gained by the engineers in developing SSA and SVA models.
But I guess ATM they're busy with SDS5000X final development......

Guess that as soon as siglent offer free vna (and others) options for free... Or if like the rigol 1054z these options can be easily enabled at home ... They will take all the hobbyist market, and sell a lot of these boxes... until  this happen sales will be slow as other competitors offer nice spectrum analyzers at about the same price

I doubt very much they will !
TG is offered free as part of the package just like it is now for the SSA whereas it was once an option.
