Points / Symbol ( Custom IQ)

Points / Symbol determines the number of points displayed between symbols for digitally demodulated data.

Minimum:	1 point per symbol
Maximum:	20 points per symbol

For example, if the value of Points / Symbol is 1, each display point corresponds to a symbol. If the value is 2, every other display point corresponds to a symbol In this case, an IQ time trace would show 1 display point between each symbol, as shown in the following illustration.

The effect of Points / Symbol can be seen by displaying an IQ trace and pressing an arrow key (on the keyboard) or turning the mouse wheel to move the marker between symbols. If the number of points per symbol is 2, moving the marker would reveal 1 distinct display points between symbols.

Additional Details

Here are some additional details:

Measurement Effects: For details about how Points / Symbol affects measurement data, see IQ Meas Time.
Saving Points / Symbol: When a digitally demodulated trace is saved , the Points / Symbol value used to create the trace is saved with the trace. When the trace is recalled, the VSA displays the trace with the Points / Symbol used to create the trace. The VSA DOES NOT use the current value of Points / Symbol.
