Tektronix 071-0590-00 Viewing Results, BER and Bit Errors, All Other Results Test Process only

Reference

Viewing Results

BER and bit error results are shown in the normal display mode. However to view the complete list of Test results, you must use the TEST Menu VIEW-CUR or VIEW-PRE functions.

BER and Bit Errors

The Analyzer calculates BER and bit errors using all three measurement methods (Totalize, Window, and Test). The current display mode determines which BER/bit error result pair is shown in the display. Note that BER is shown in the top, middle field while the bit error result is shown in the top, right field.

Procedure to View Desired BER and Bit Error Results

Press the DISPLAY SELECT key to select the appropriate display mode.

As noted earlier, the character in front of the BER result will indicate the current display mode. The infinity symbol (∞) indicates Totalize; a blank character indicates Window; and the T, U, or R characters indicate Test results which have been measured using the timed, untimed, or repeat timing modes respectively.

All Other Results (Test Process only)

To view the complete set of Test results, select the VIEW-CUR or VIEW-PRE functions from the TEST Menu. VIEW-CUR will show partial results if a timed test is in progress, or results from the last completed test. VIEW-PRE will show results saved in the "previous" test registers. These results are over-written with the contents of the current registers each time a test is completed.

Procedure

1.Press F1 to enter the Menu system.

2.Select the TEST Menu (F2).

3.Press MORE (F1) twice to view the third page of the TEST Menu.

4.Select either VIEW-CUR or VIEW-PRE to view all current or previous Test results respectively. Once inside either the VIEW-CUR or VIEW- PRE function, use the pattern up/down keys to scroll through the results list.

5.When done, press F1 multiple times to exit the Menu system.
