Span
( Span Frequency )
DEV_DOUBLE
READ_WRITE
No
CenterFrequency
( Sets or retrieves the central frequency. This is listed in the base IVI Spec functions. )
DEV_DOUBLE
READ_WRITE
No
MarkerX
( Positions the active marker on a signal peak. IVI Spec compliance: IviSpecAnMarker Extension Group. )
DEV_DOUBLE
READ
No
MarkerY
( The point on the y-axis corresponding to the value of the marker IVI Spec compliance: IviSpecAnMarker Extension Group. )
DEV_DOUBLE
READ
No
ErrorPolling
( This function periodically polls the device and reads its status, signaling malfunctioning. )
DEV_STRING
READ
No
Attenuation
( Specifies the input attenuation (in positive dB). From 0 to 70. IVI Spec base attribute. )
DEV_DOUBLE
READ_WRITE
No
DetectorType
( Specifies the detection method used to capture and process the signal. Accepted: NEG POS SAMPle APEak IVI SpecAn base attribute. )
DEV_STRING

StartFrequency
( Sets the start frequency. Sets the start frequency. IVI SpecAn base functions. )
DEV_DOUBLE
READ_WRITE
No
StopFrequency
( Sets the stop frequency. IVI SpecAn base functions. )
DEV_DOUBLE
READ_WRITE
No
FreqOffset
( Specifies the frequency offset for all frequency readouts such as center frequency, except that it does not affect marker count. IVI SpecAn base functions. )
DEV_DOUBLE
READ_WRITE
No
ReferenceLevel
( Sets the amplitude of the reference level for the y axis. This is used as reference for amplitude measurements. This is typically set to a value slightly higher than the highest expected signal level. The units are determined by the amplitude units attribute. IVI SpecAn base attributes. )
