Digital...

Set the digital input properties for a logic analyzer.

 

 

Capture...

Set the time-domain parameters for fixed-length and variable-length segmented time-captures.

 

 

Trigger...

Select the type of trigger signal to use for an input channel (non-Power Spectrum measurements only)

Playback User Correction...

Configure corrections to apply to a recorded signal during playback (Data From Recording).

 

 

IQ Noise Correction...

Compensate the acquired signal such that the measured EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. will not include the contribution from the analysis hardware.
