Description of Arguments
Query only.
Unit returns equipment identification and configuration, where:
aaa = defines the modulator model number (710)
b = Modulator configuration:
1=70/140 Mhz, 2=L-Band
c = Tx Symbol Rate S/W option: 0 = 15.0 Msps,
1 = 22.5 Msps, 2 = 30.0 Msps,
3 = 37.5 Msps (S1 and DSNG only),
4 = 45.0 Msps (S1 and DSNG only)
d = S/W option Tx 8PSK: 0=Not installed, 1=Installed
e = S/W option Tx 16-QAM: 0=Not installed, 1=Installed
f = S/W option Tx 16APSK: 0=Not installed, 1=Installed
g = S/W option Tx 32APSK: 0=Not installed, 1=Installed
h = S/W option Tx DVB-S1: 0=Not installed, 1=Installed
i = S/W option Tx DVB-DSNG: 0=Not installed, 1=Installed
j = S/W option Tx DVB-S2: 0=Not installed, 1=Installed
k = Demodulator configuration:
0=None, 1=70/140 Mhz, 2=L-Band
l = Rx Symbol Rate S/W option: 0=15.0 Msps,
1 = 22.5 Msps, 2 = 30.0 Msps,
3 = 37.5 Msps (S1 & DSNG only),
4 = 45.0 Msps (S1 & DSNG only)
m = S/W option Rx 8PSK: 0=Not installed, 1=Installed
n = S/W option Rx 16-QAM: 0=Not installed, 1=Installed
o = S/W option Rx 16APSK: 0=Not installed, 1=Installed
p = S/W option Rx 32APSK: 0=Not installed, 1=Installed
q = S/W option Rx DVB-S1: 0=Not installed, 1=Installed
r = S/W option Rx DVB-DSNG:0=Not installed, 1=Installed
s = S/W option Rx DVB-S2: 0=Not installed, 1=Installed
t = Interface slot #1: 0 = None, 1 = ASI, 2 = Gigabit Ethernet
Interface, 3 = HSSI
u = Interface slot #2: 0 = None, 1 = ASI, 2 = Gigabit Ethernet
Interface, 3 = HSSI
Query only.
Unit returns the value of EsNo (when in DVB-S2 mode), between 0 and 16 dB,
resolution 0.1 dB.
Returns 99.9 if demod is unlocked.
Example: ESN=12.3 (Es/No specified is 12.3 dB)
For values greater than 22.0 dB, the reply will be: ESN=+022
Command or Query.
Set redundancy mode in the form x, where :
0 = Disable
1 = Enable
Example: ESW=1 (Redundancy Mode enabled)
