6.1.6 5.4 GHz Product Variant - Receive Sensitivity, Link Loss, Output Power and Threshold Vs
Modulation Mode
The equipment capability is given in
1022HTable 11. This table gives Receive Sensitivity, Link Loss
and Output Power for PTP 600 Series Bridge in all modulation modes for channel bandwidth
equal to 30 MHz. The values for Receive Sensitivity are typical values in a flat radio channel
for an Ethernet frame loss rate of 3E-5. For minimum error rates on TDM links the maximum
modulation mode should be limited to 64QAM 0.75.
The un-shaded value above (BPSK) is a static receive sensitivity measurement. The shaded
values above are static receive sensitivity measurements with an AMOD threshold applied.
The AMOD threshold applied is for a benign radio channel.
