This menu includes the following display-only fields:
Sample Points
Displays the total number of sample points in the recalled IQ data file. If you have
not recalled an IQ data file, the value is 0.
Sampling Time
Displays the total sample time of the recalled IQ data file. If you have not recalled an
IQ data file, the value is 0.
Input Channels [Mode: 5GNR, VMA, WLAN]
Displays the input channel number of the recalled IQ data file. If you have not
recalled an IQ data file, the default value of 1 is displayed.
This control is designed for multi-channel I/Q data recording and playback.
Playback Mode
Specifies the mode of IQ data to be played back and analyzed:
–
Fixed: Playback Stop value is ignored. Measurement will analyze the first chunk
of IQ data start from Playback Start repeatedly
–
Iterative: Measurement will analyze the IQ data chunk by chunk between
Playback Start and Playback Stop, if the last chunk is not complete it will be
ignored and start from the first chunk again
