7.2.32 Data Type
Allows you to recall IQ data from the measurement using a specified file type (CSV,
SDF, TXT, BIN, BINX, BINF, ORB). See "Recording" on page 2244 for details
about the available file types.
Note that BIN, BINX and BINF files do not include sampling rate information inside
the file, so after recalling one of these file types you will need to set the Sample Rate
in Sweep, Playback., based on your note of the Sample Rate that was displayed on
the Sweep, Recording menu panel when you saved the file.
Example
:MMEM:LOAD:RECording "C:\TEMP\MyIQData.csv"
7.2.33 Channel
Select data channels to recall. This is only supported in the 5GNR EVM, VMA Digital
Demod, VMA Custom OFDM and WLAN MIMO EVM measurements.
The <meas> param in the command must be replaced with the node of the active
measurement:
–
EVM for 5GNR EVM
–
EVMM for WLAN MIMO EVM
–
DDEM for VMA Digital Demod
–
OFDM for VMA Custom OFDM
