Differences Between The M9391 And M9393 - Keysight Technologies M9393A Programming Manual

Differences between the M9391 and M9393

The major differences between the M9391 and M9393 are as follows:
M9393 supports noise correction, M9391 does not.
M9393 supports digital image rejection, M9391 does not.
M9391 has a dual-downconversion path across most of the band, M9393
only has this in the narrowband.
M9393 has a Stepped Spectrum IVI interface, M9391 does not.
M9393 has a MultiAcquisition mode in addition to the List mode, M9391
does not.
M9393 has two IF filter bandwidths, where M9391 has only one.
M9393 has three different offset adjustments: IF, digitizer, and mixer,
whereas M9391 only has two.
The interface for alignments is slightly different: there are more options with
M9393. Additionally, the alignments are stored in EEPROM, alignments
therefore don't need to be re-run in between IVI sessions.
M9393 has a Live SFP, M9391 does not.
M9393 requires that the RF input have no incident signal when performing
alignments, M9391 does not.
M9393 has a broadband trigger in addition to the other triggers present for
the M9391.
