I am using two TSW1400 for my project, and I just realize that the HSDCPro is not able to connect to both of them at the same time. Anyone got an idea how to communicate to both TSW1400 simultaneously?
Thanks.

Hi Jim,
I got another question about using HSDCPro Automation DLL with Matlab. Is there a function allows me to save the tone that generated by the IQ Multitone Generator? I can save the IQ data as the .csv file by using the GUI, but I do not see any function in the Automation DLL.
Thanks.
Hi,
You can use the Save as CSV function to save the tone generator data.

Hi Matt,
I think I got trouble to generate the CSV file.
I am using an Automation DLL Matlab function "Save_Raw_Data_As_CSV".
Every time I generate the tone and save it, it comes up with a CSV file that with 4 columns data instead of 2 columns.
I think it used to be 2 columns...do you know how should I solve this problem?
Thanks,
Zi.
Hi Zi,
The 3rd and 4th column would be used for DAC C and D of a quad DAC. If you're only using a dual DAC then HSDCPro will ignore columns 3 and 4. Alternately you can open the file and delete the 3rd and 4th column.

Hi Matt,
Thanks for the reply.
For the TSW30SH84, if I use 10MHz external reference, can I also use the 10MHz from REF OUT (J16) to reference other devices?
In my case, I need to referance TSW1266 as well.
Thanks,
Zi.
Hi,
I got one more question about the referance clock.
For TSW30SH84 and TSW1266, if I only have 25MHz external references available instead of 10MHz, how should I program these two boards to make them work under 25MHz reference? Or I can just use the same setting for the 10MHz external reference, which is given by the default demo file.
Thanks,
Zi.
Hi Zi,
If you have a 25 MHz reference you want to lock to then you'll need to change the clock PLL settings to lock your 25 MHz reference to the VCXO on the EVM. For the TSW1266, the VCXO is 122.88 MHz, so you need to find a common PFD frequency that can be generated from 122.88 MHz and 25 MHz using integer dividers. It looks like an R divider of 625 and an N divider of 3072 could work.
I believe the TSW30SH84 can output a 10 MHz reference which could be used by the TSW1266 to lock it's clocks to. This would be easier than trying to lock both boards to 25 MHz.

Hi Zi,
Did you load the TSW1266 configuration file called "LMK04808_614p4M_Dual_Loop_10M_Ref.txt"? I believe this file should work.
