Programming Commands
CALCulate3 Subsystem
ASNR[:STATe]
Turns the average signal-to-noise ratio on or off.
Syntax
:CALCulate3:ASNR[:STATe] {?|{ ON | OFF | 1 | 0 }}
Attribute Summary Preset State: off
*RST State: off
SCPI Compliance: instrument specific
Description This command turns the average signal-to-noise calculation on or off. Only one of
the CALCulate3 calculations (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 conflict” error.
When the calculation is first turned on, the lines measured in the current measure-
ment will be used as the reference values for the signal-to-noise ratio. Subsequent
measurements will average the noise values. The signal values are not updated until
the number of measurements 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.
Refer to “Measure delta, drift and signal-to-noise” on page 94 for additional
information on selecting measurements.
