1. ODU 300ep availability is now restricted to 5, 13 and 15 GHz. It is required for 5 GHz and is an option for 13 and 15 GHz.
2. A QPSK-only ODU 300sp is available for frequency bands 8, 13, 15 GHz.
Tx Power Control Range
Tx power is programmable in 0.1 dB steps, with an accuracy of +/-2dB over range and

ODU 300hp and ODU 300ep Compatibility
These units are air-compatible, but the following points should be considered:
• When sparing an ODU 300hp with an ODU 300ep (or vice-versa), both ODUs must
be on the same frequency band and the selected sub-band option must support the
carrier spot frequencies. In some cases the sub-band options differ. Refer to the
Eclipse Tuning Guide for guidance, which is available from HSX Help Desks.
• ODU 300hp weighs 6.4 kg, whereas the ODU 300ep weighs 8.3kg.
• ODU 300hp power consumption is nominally 40W, whereas the ODU 300ep
consumption is 50W. Where appropriate, consider the impact on site power supply
loading when sparing an ODU 300hp with an ODU 300ep.
• The Tx power control range for the ODU 300hp and the ODU 300ep differ. See
Table
attenuated links when substituting an ODU 300ep with an ODU 300hp.
• The Tx output power and Rx sensitivity figures for ODU 300hp and ODU 300ep vary
depending on the ODU frequency band. Refer to the Eclipse datasheets for specific
details. Differences should be considered to ensure target design fade margins are
maintained when substituting ODU 300ep for ODU 300hp, and vice-versa.
• In a protected RAC40/RAC 4X pairing, support is provided from SW release 4.3, for
mixed ODU 300hp and ODU 300ep operation. Mixed hp/ep operation in protected
RAC 40/4X configurations prior to this release is not recommended.
