:CALCulate3:DATA? {POWer | FREQuency | WAVelength}
Attribute Summary
Description
This command turns the average signal-to-noise calcu-
lation on or off. Only one of the CALCulate3 calcula-
tions (ASNR, DELTa, DRIFt, or SNR) can be turned on
at a time. Turning on the ASNR calculation while
another calculation is on will generate a "Settings con-
flict" error.
When the calculation is first turned on, the lines mea-
sured in the current measurement will be used as the
reference values for the signal-to-noise ratio. Subse-
quent measurements will average the noise values. The
signal values are not updated until the number of mea-
surements used to average the noise is greater than or
equal to the COUNt value.
Note
Only one STATe command can be turned on at any one time.
Attempting to turn more than one state on at a time results in a
"–221 Settings Conflict" error.
