You can switch waveform playback license mode to take advantage of an instrument license, even when a PC license is available with the parameter "Playback License Mode" under the "Waveform" tab, "Basic" group.
Playback License Mode has 2 selections: PC License | Instrument License
When "PC License" is selected, "Waveform Name" should be hidden (you cannot change the waveform name). And Waveform Name API is read-only (not accepting waveform name change).
When a valid PC license (APPC) exists, this parameter is active and you can choose either one. Default is "PC License."
When a valid PC license does NOT exist, this parameter is read-only and "Instrument License" mode is selected.

CCDF |
The CCDF graph displays the probability (in percentage) that the generated waveform's calculated peak-to-average power ratio (measured in dB) is greater than or equal to a specified level. The table to the left of the CCDF plot displays the calculated peak-to-average values for the current waveform. Reference - Select to view the reference curve.
