Data Test

This group displays information about the SDI interface test when running in PRBS
mode in the patter generator.

Data rate

—Displays the current SDI data rate in megabytes per second (MBps).

Freq

—Displays the data rate frequency in MHz which is equivalent to Mbps.

Bits

—Displays the number of bits transmitted since clicking Start.

Inserted errors

—Displays the number of errors inserted by clicking Insert Error

button.

Detected errors

—Displays the number of bit errors detected by the error checking

circuitry.

BER

—Displays the bit error rate of the interface.

PLL lock

—Displays Yes if the SDI PLL is locked.

Pattern Sync

—Displays Yes if the receiver has detected the input data pattern.

Start—

Starts the PRBS data test and begins to monitor and update screen with

live test results.

Stop

—Stops the PRBS data test.

Insert Error

—Inserts an error into an SDI data stream that is detected by the

receiver when in loopback using the included video cable.

Clear

—Clears the Detected errors counter.

PMA Setting

—Opens the PMA settings window that allows for adjusting the

analog transceiver settings, such as output voltage, loopback settings, and
equalization.

PRBS

(list)—Selects the transmit pattern and sets the receive error detection

circuitry to expect the same pattern for use in loopback testing.
