QD LNB Off, 13V, 18V Off Sets the low noise block (LNB) voltage of the demodulator.
■
Off – sets voltage to zero; no power to LNB
■
13V – sets the LNB voltage to 13 V (horizontal polarization)
■
18V – sets the LNB voltage to 18 V (vertical polarization)
Note : The TDR60 supplies the LNB power at 13 V DC or 18 V DC,
which allows an LNB downconverter to set the receive signal
polarization to either horizontal or vertical. If you do not need the
TDR60 to supply the LNB power, set to Off.
Note : This command is only applicable when Inp Type is set to
Demod.

QD LO 2000 to 15000 MHz 10000 Sets the frequency of the demodulator to match your LNB
downconverter local oscillator frequency.
Note : This command is only applicable when Inp Type is set to
Demod.

QD LOCK DEMOD Locked, Unlocked — Displays the current lock status of the demodulator.
Note : This command is only applicable when Inp Type is set to
Demod.

QD LOCK DECODER Locked, Unlocked — Displays the current lock status of the decoder.
Note : This command is only applicable when Inp Type is set to
Demod.

QD OFFSET frequency in KHz — Displays a measurement in KHz of the difference between the actual
receive carrier frequency and the frequency determined by subtracting
the LO Freq parameter from the FR Freq parameter.
To achieve carrier (transport stream) lock, the difference between the
two frequencies, or the Offset, must be less than 2 MHz; however, to
achieve optimum performance, the Offset should be as close to zero
as possible.
TDR60 Acquisition Time related to Frequency Offset is as follows:
Acquisition Time
Frequency Offset
< 12 seconds < ± 500 KHz
< 30 seconds < ± 1 MHz
< 70 seconds < ± 2 MHz
< 100 seconds < ± 3 MHz
Note : This command is only applicable when Inp Type is set to
Demod.

QD RF 2000 to 15000 MHz 11210 Sets the demodulator to the frequency of the incoming RF signal.
Acceptable ranges are 950 to 2150 MHz above or below the local
oscillator frequency.
Note : This command is only applicable when Inp Type is set to
Demod.
