Opcode: <224Fh> Command a modulator's PRBS (test pattern)
<1> PRBS (0 = Normal, 1 = PRBS23, 2 = PRBS23M, 3 = PRBS15, 4 =
PRBS15M)
Opcode: <2251h> Command a modulator's Base Band Loopback
<1> BB Loopback (0 = Normal, 1 = Loopback)
Opcode: <2253h> Command a modulators output power level
<4> Tx Power Without cable Upconverter, value is in dBm.
(Signed value. +00 to -250 (+0.0 to -25.0 dBm)
(Implied decimal point)
Ex: +0.0 dBm, data returned = 00 00 00 00 = 00 decimal = +0.0
dBm
Ex: -25.0 dBm, data returned = FF FF FF 06 = 100000000 –
FFFFFF06 = FAh = 250 = -25.0 dBm
With cable Upconverter, value is in dBv.
(Signed value +450 to +600 (+45.0 to +60.0 dBv)
(Implied decimal point)
Opcode: <2254h> Command a modulator's carrier control
<1> TX Enable (0=Off, 1=On)
Opcode: <2255h> Command a modulator's carrier test
<1> TX Carrier (0=Normal, 1=CW)
Opcode: <2260h> Command a modulator's channel table
<1> Channel Table (0 = EIA STD, 1 = EIA HRC, 2 =EIA IRC, 3 = Trad STD, 4 = Trad
HRC, 5 = Trad IRC)
Opcode: <2261h> Command a modulator's channel
<1> Channel (See channel entry tables at end of protocol)
