Read Only
Input AGC Mode
Automatic Gain Control mode, if set to on then the broadcast
digital attenuator is automatically adjusted to provide RF power
levels at laser input for optimum OMI.
heOpTxInputAGCMode
RW
Input Modulation Mode
Either CW or modulated. This variable affects the calibration of
the RF power detector. There is approx a 2 dB difference seen
by the power detector if a CW or modulated carrier of the same
power is applied.
heOpTxInputModulationMode RW
Input Attenuation, BC
Input Attenuation, NC
Input digital attenuators. See MPTX functional diagrams to see
location of the BC (Broadcast) and NC (Narrowcast)
attenuators. 0-15 dB in 0.5 dB steps.
heOpTxInputRFPadLevel
RW
Laser Temperature
Laser Temperature.
heOpTxLaserTemp
RO
Laser Bias Current
Laser Bias Current.
heOpTxLaserBiasCurrent
RO
Laser Output Power
If a 10dBm laser is ordered, this variable will be close to 10 dB,
with some variation as individual lasers are tuned for optimum
OMI.
heOpTxLaserOutputPower
RO
Laser TEC Current
Thermo-Electric cooler current.
heOpTxLaserTECCurrent
RO
Laser Type
Typically “Cooled DFB”.
heOpTxLaserType
RO
Laser Wavelength
Factory set wavelength of laser.
heOpTxLaserWavelength
RO
Laser Output Status
A read-only field to indicate what Laser On/Off control is set to.
heOpTxLaserOutputStatus
RO
Laser On/Off Control
A writable field. Laser is muted if set to off.

OptRx Input Power
Measured optical power input (max +3dBm).
heOpRxInputPower
RO
OptRx Input Wavelength
Optional, user-settable integer to store the wavelength of
operation. This value has no effect on the operation of the
device.
heOpRxInputWavelengthControl RW
OptRx Input Status
If optical input power is beyond thresholds, this will be in
fault
condition.
heOpRxInputStatus
RO
OptRx Output Control
Allows the user to mute the RF output.

OptRx Output RF
Attenuation
Control of RF output attenuation level (0-31.5 dB in 0.5 dB
steps).
