short pn code
Hi xinxin
in cdma,
Walsh code is for chanelization
short PN code is for identifying the BTS
long PN code is for identifying the MS
all PNs and Walsh code are orthogonal code
hope this help

oscillator 900mhz
Hello,
Would you please tell me some Local Oscillator operating at :
870 ± 30 Mhz
error ±5Khz
Mixer at this range with minimum signal power at -132dB (or tell me about some LNA for this range compensation)
Thanks for advances

Re: Communication in PLC MMI
1. You must know the protocol of the PLC
2. write the the code
3. try it
some PLC use point to point comm thru COM port (RS232/485/422)
so you can talk with it
some use other protocol (profibus, fieldbus, ...can....) so you must buy a prorietary communitcation...
- easy to learn
- you may use ct visual basic for application instead of traditional ccod
- you can use much more utilities
- it support almost industrial protocol and comm hardware
regards
I used ct5.41 and not have any bugs, for bug known, i think you should get the relnote from ct homesite.
theres much facilities there, network and ....
Goodluck

Hi all,
i have a gigatronics 12720A microwave synthesizer and want to use it to generate 13 bit Barker code at 200Mhz carrier wave for testing my signal receive block.
can anybody tell me how to do
thanks in advance
