Parameters / Response Values

 

 

 

Raw BER

Query-only; displays the raw bit error rate; this rate is the error

 

rate of the signal as it is received from the satellite, before error

 

 

correction is applied.

 

 

 

 

BER

Query-only; displays the bit error rate; this value represents the

 

number of errors detected in the signal after error correction is

 

 

applied. This rate should be a zero for correct performance.

 

 

 

 

Rx Level

Query-only; displays the power level of the input signal.

value in .dBm

 

 

 

Peak Jitter

Query-only; displays the difference, or jitter, between the STC

value in ns

 

and PCR clocks.

 

 

 

 

Details>Input>Status>ASI: allows you to query the presence of the ASI signal, as well as other transport stream parameters

Signal

Query-only; displays if the ASI signal is present or not

Present, Absent

 

Note: Signal is only available when

 

 

Details>Input>Config>Select>Input is set to ASI.

 

 

 

 

Transport

Query-only; displays the lock status of the transport stream

Locked, Unlocked

 

 

 

Rate

Query-only; displays the output rate for the QPSK demodulator

value in bps

 

 

 

Peak Jitter

Query-only; displays the difference, or jitter, between the STC

value in ns

 

and PCR clocks.

 

 

 

 

Details>Service: consists of two submenus, Number and Auto Select, which enable you to query and select the services available in the transport stream.

Once you have selected a service, the Video Decoder, Audio Decoder, and User Data menus display the PIDs available for the selected service.
