:CHANnel:SIGNal:TYPE
Command Syntax
:CHANnelN:SIGNal:TYPE {UNSPecified | NRZ | PAM4}
Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.
Query Syntax
:CHANnelN:SIGNal:TYPE?
Description
Manually sets a channel's signal type when automatic detection is turned off (:SIGNal:TYPE:AUTO). This can be useful if the waveform is too degraded to automatically detect its type. By default, automatic detection is turned on and is performed as part of an autoscale (:SYSTem:AUToscale). Automatic detection can also be manually run using the :SYSTem:STAutodetect command. This has the advantage of detecting the signal type without performing scaling. After automatic signal detection, use the :CHANnel:SIGNal:TYPE? query to return the actual signal type that was detected. A waveform can be detected as a NRZ formatted data, or PAM4 formatted data. The default signal type is Unspecified. Sending this command with automatic detection turned on results in a settings conflict error.
Example Command Sequence
:CHANnel2A:SIGNal:TYPE:AUTO OFF :CHANnel2A:SIGNal:TYPE PAM4
The PAM4 argument is only available if options 9FP or 9TP PAM-N Analysis software license is installed.
