Question about iDirect 3100 Option file

Hello,

I have question about Idirect Modem Option file. I would want to know the Symbol Rate and Receive frequncy.

Lets say I have one Option file for one Idirect modem and might be there some problem that I can not Point the antenna through ISITE....  how should I find the symbol rate and Frequncy to Point the antenna with Satellite Meter.

Hi Mike

As per below example. Let say I want point or track it by Horizon satellite meter. How should I put freq and symbol rate on it.

[MODEM_PARAMETERS]
rx_freq = 1213000000
rx_acqrange = 100000
rx_bitrate = 4097132

Thanks in advance

QPSK is correct.

rx_modtype:

0 = BPSK
1 = QPSK
2 = 8PSK
3 = 16 PSK

15 is normally indicative of long block 3249/4096. Possibly .495.....Give me some time and I will run it to ground.

M

I've solved it.  Just seen someones option file and screen display.

FEC code 15 means 3249/4096 = 0.793

So anyone can now work out symbol rate is they are less than 8.2.2 using:

rx_modtype:
0 = BPSK
1 = QPSK
2 = 8PSK
3 = 16 PSK

rx_fecrate
15 = 0.793
20 = 0.533

Best regards, Eric.
