Anyone know about Chinese StarPoint SP6300 or SP6200 TD-SCDMA analysers. I want to know if these are comprised of PXIe chassis and modules.

I am very curious as well, as they are relatively cheap. But not cheap enough if there's no indication that they are built from general-purpose test equipment.
I wasn't able to find neither software nor a manual or real specifications. The layout of the fans and the power supply doesn't ring a bell, nor does the usage of the HDMI "cascade" ports. Closest is probably PXIe-1095 ref/trigger port, but that seems to be more coincidence than evidence.

My Starpoint SP6300 arrived today. I purchased cheapest I could get. Built like a brick out house!! All steel plate case weighs an easy 24 Kg. Big too (50x23x59cm).
Inside is a ADLINK PXIS-2670 PXI 14 slot backplane.
Controller is ADLINK 3920 (Pentium M 2GHz, 2GB RAM, PCI-3488/348A GPIB, 160GB SATA ).
Aeroflex PXI VNA / VSA comprising 1 each:
- 3011 Synth OCXO;
- 3030A 330~3.3GHz RF Digitizer;
- 3060 RF Combiner;
- 3010 Synth;
- 3020A 250MHz ~ 2.5GHz RF Generator
There is also 3x Jungo TMS320C6205 Floating Point DSP PXI which I guess is where all the LTE signal processing occurs.
Power supply is EMACS HP2-6500P 500W
Fired up OK but was password locked. Hacked that and found system running Windows 7 pro. Its not fast but also not as slow as I expected 2GHz Pentium M with 2GB RAM. Probably SATA HDD helps. A SSD would surely speed things up more. 2GB is maximum I think.
Given LTE is dead the main use could be RF generation & analyses from 250MHz to 3GHz. As it stands, no physically free slots but if I pull the 3x Junbgo DSPs that will give me 6 slots free as each board had a 1 slot spacer. So would be easy enough to add more NI PXI lab gear - digitizer, multimeter, etc.
A bit disappointing as I was hoping for RF gear down to 1MHz and a smaller platform for my bench space. But well worth the $482 I paid to get it here (15% was local tax, actual unit was US$300).
A better option is the Aeroflex 7100 which has 2x sets of analyzers that cover from 500kHz to 6GHz but the Aeroflex controller is not a PXI plug in module - its bolted onto the back of the PXI backplane.
