4.2 Front Panel Interface

Figure 8. N4962A front panel

The N4962A front panel indicates system configuration, and can be used for

local operation of the instrument. The front panel contains three groupings of

buttons and lights (local, receiver, and data path controls; configuration

adjustment controls; and display selection controls), a display panel and error

light, and the PRBS generator (SOURCE) and error detector (RECEIVER)

connectors.

The PRBS generator connectors, labeled SOURCE, are 2.92 mm K-connectors.

The PRBS output is available in single-ended or differential form from these

connectors. The output signal is specified in Section 3.3.

The error detector connectors, labeled RECEIVER, are SMA connectors. The

input bit stream (from the output of the DUT) can be connected in single-ended

or differential form to these connectors. The input signal requirements are

specified in Section 3.4.

To use either the SOURCE or RECEIVER connector pairs in a single-ended

configuration, terminate the unused RF connector in a 50 Ω termination. To use

the connectors differentially, ensure the cables used are phase balanced – the

same electrical length – to avoid errors caused by out-of-phase differential

signals.
