Marker Function
When Band/Interval Power is selected while in the Marker Function Off state, the Band Span or Interval
Span
is initialized to 5% of the screen width.
If the detector mode for the detector on the marker’s trace is set to Auto, the average detector is
selected. If the Average type is set to Auto, Power Averaging is selected. Other choices for the
detector or Average type will usually cause measurement inaccuracy.
Key Path Marker Function
Example CALC:MARK:FUNC BPOW turns on marker 1 as a band power marker.
CALC:MARK2:FUNC? returns the current setting of marker function for marker 2. In this case it
returns the string: BPOW.
CALC:MARK:Y? returns the y-axis value of the Band Power function for marker 1. Note that the
delta value when the Y axis unit is Watt is the square of the delta value when the Y axis unit is
Volt. For example, when the percent ratio with Y axis unit in Volt is 0.2, the percent ratio with Y
axis unit in Watt will be 0.22 = 0.04. When you read the value out remotely you have to know
whether your Y Axis Unit is log (dB), linear (V or A), or power (W).
Notes See the description under the “ "Marker Function" on page 729 ” key, above.
Dependencies Fixed markers: It is not possible to change the Band Function for a Fixed marker, so all of the
Band Function keys are grayed out for a Fixed marker.
Couplings If the detector mode for the detector on the marker’s trace is set to Auto, the average detector is
selected. If the Average type is set to Auto, Power Averaging is selected.
If the selected (specified) marker is off, selecting Band Power via thefront panel or SCPI will turn
the marker on.
Initial S/W Revision Prior to A.02.00
Band/Interval Density
Turns on the Band/Interval Density function for the selected marker. If the selected marker is off
it is turned on in Normal marker mode and located at the center of the screen.
When Band/Interval Density is selected while in the Marker Function Off state, the Band Span or Interval
Span
is initialized to 5% of the screen width.

Example CALC:MARK:FUNC BDEN turns on marker 1 as a band density marker.
