"Off" The signal is muted immediately.
If the level changes, the playback of the play file is not interrupted.
Level changes include the settings "Volt Peak Ch1", "Volt Peak Ch2",
"Volt Ch2/1", "Filter" and "DC Offset". For all other generator settings
that change the physical properties of the signal, the signal is muted.
Only the activation of the item "Once" or START causes the playback
of the play file to restart.
"Auto" The playback of the play file is restarted with any setting in the gener-
ator panel.
"Once" Forces the restart of the playback of the play file only once.

Play Mode
Determines the playback mode of the loaded WAV file.
"Total Cont" The complete WAV file is played back in a loop; when the end of the
file is reached, playback jumps back to the beginning of the file with-
out interruption.
Note: During the jump back, the signal normally becomes discontinu-
ous, which for pure sine-wave signals, is visible as noise in the spec-
trum close to the carrier.
"Total Single" The complete WAV file is played back once, after which the generator
is muted.
"Time Cont" The beginning of the WAV file is played back in a loop. After the play-
back time expires, playback jumps back to the beginning of the file
without interruption.
"Time Single" The beginning of the WAV file is played back once; after the playback
time selected in the next menu field expires, playback stops and the
generator is muted.

Time
Used to display or enter the playback duration.
Since the R&S UPP cannot output WAV files online, a maximum of 16 Msamples of a
WAV file can be played back. The maximum playback duration is calculated using the
number of samples in the WAV file and the sampling rate. With a sampling rate of 48
kHz, this calculation results in a maximum playback time of approx. 350 s.
