3 Spectrum Analyzer Mode
3.2 Swept SA Measurement
When in Zero Span (for measurements that support Zero Span), the label on this
control changes to Marker Time. When Marker Mode is Delta, the label changes to
Marker Δ Frequency or Marker Δ Time.
The remote command sets the marker X-Axis value in the current marker X-Axis
Scale unit. The marker that is addressed becomes the selected marker. It has no
effect (other than to cause the marker to become selected) if the control mode is Off,
but it is the SCPI equivalent of entering an X value if the control mode is
Normal,Delta, or Fixed.
Remote Command
:CALCulate:MARKer[1]|2|…|24:X <freq | time>
:CALCulate:MARKer[1]|2|…|24:X?
Example Turn on Marker 2 as a Normal marker
:CALC:MARK2:MODE POS
Move Marker 2 to 20 GHz:
:CALC:MARK2:X 20 GHZ
Query the amplitude of Marker 2:
:CALC:MARK2:Y?
Notes If no suffix is sent, Marker Frequency | Time uses the fundamental units for the current marker X Axis
Scale. If a suffix is sent that does not match the current marker X Axis Scale unit, an invalid suffix
message is generated
If the specified marker is Fixed, and a Marker Function is on, a message is generated. If the control is
pressed, an advisory message is generated. If the equivalent SCPI command is sent, this same
message is generated as part of a “–221, Settings conflict” warning
The query returns the marker’s absolute X Axis value if the control mode is Normal or Fixed. It returns
the offset from the marker’s reference marker if the control mode is Delta. The query is returned in the
fundamental units for the current marker X Axis scale: Hz for Frequency and Inverse Time, seconds for
Period and Time. If the marker is Off, the response is Not a Number
The Marker Amplitude query is discussed under "Marker Amplitude" on page 312
Dependencies Grayed-out, and displays three dashes for the value, when the selected Marker is Off
You cannot directly set the X value of a Fixed marker that has a marker function turned on If an
attempt is made to adjust it while a Marker Function is on, a warning message is generated
Preset After preset, if X is queried with no value sent first, the center of screen value is returned. The actual
value depends on the frequency range of the instrument
Min/Max –/+¥ (minus infinity)
Unlike legacy analyzers, where the markers were forced to be on screen, X-Series marker values are
not limited and do not clip
Marker Backwards Compatibility
–
In earlier HP/Agilent/Keysight analyzers, markers were position markers, which
means that Normal and Delta markers stayed at the same screen position when
X Axis parameters were changed. So, a marker at center screen stayed at center
