:MASK:RELative:UPPer:POINts:FREQuency1 (through FREQ15) :MASK:RELative:UPPer:POINts:FREQuency1? (through FREQ15)
These commands set/query the frequency (Hz) of the defined points on the upper spectrum analyzer mask.
The units for the mask are GHz, MHz, kHz, and Hz.
Syntax
To define the frequencies in a four-point mask:
SAN:MASK:REL:UPP:POIN:FREQ1 <real number>
SAN:MASK:REL:UPP:POIN:FREQ2 <real number>
SAN MASK:REL:UPP:POIN:FREQ3 <real number>
SAN:MASK:REL:UPP:POIN:FREQ4 <real number>
SAN:MASK:REL:UPP:POIN:FREQ1?
Screen/field equivalent
SAN:MASK:REL:UPP:POIN:FREQ1 controls the Freq Ofs field on the Mask menu of the SPEC ANL when the EditPt field is set to 1, the Edit Mask field is set to Upper, and the Mask Type field is set to Rel.
:MASK:TYPE
:MASK:TYPE?
This command selects/queries the type of mask, fixed or relative. ‘Fixed’ sets the mask in absolute frequency and level points. ‘Relative’ sets the mask relative to the center frequency and reference level set with the SAN:CFR and SAN:RLEV commands. If the center frequency is changed after setting the mask, the mask remains in the same position on the screen, and measurements are now relative to the new center frequency and reference level.
Syntax
SAN:MASK:TYPE ‘Fix’ ‘Rel’
SAN:MASK:TYPE?
Screen/field equivalent
SAN:MASK:DISP controls the Mask Type field on the Mask menu of the SPEC ANL screen.
