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 eld to indicate what Laser On/Off control is set to. heOpTxLaserOutputStatus RO
Laser On/Off Control A writable eld. Laser is muted if set to off. heOpTxLaserOnOffControl RW

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. heOpRxOutputControl RW
OptRx Output RF
Attenuation
Control of RF output attenuation level (0-31.5 dB in 0.5 dB
steps).
heOpRxOutputRFPadLevel RW
RF Amp Output
Description
Description of the approx gain value of the amp. heRFAmpOutputDescription RO
RF Amp Output Level
[dBmv]
Composite RF level at output of amp. heRFAmpOutputLevel RO
Voltage Out
Measured voltage supplied to the chassis.
(power supply modules only)
hePsOutputVoltage RO
Current Out
Current supplied to the 24V rail by the module.
(power supply modules only)
hePsOutputCurrent RO
Power Out
Voltage Out * Current Out.
