might return 1.0000E+6, indicating
that the vertical scale has been set to 1 MHz/division.
RF:RF_PHASe:LABel
This command specifies the label for the RF Phase vs. Time trace.

Arguments
<QString> is a quoted string of up to 32 characters.
RF:RF_PHASe:REFERence:DEGrees
This command sets or returns the phase, in degrees, at the trigger point for the
RF_PHASe time domain trace. The value can range from –180 to +180 degrees.
The default is 0.0 degrees and the resolution is 1.0 degrees.
Conditions

RF:RF_PHASe:VERTical:POSition
This command specifies the vertical position for RF Phase vs. Time trace. The
position value determines the vertical graticule location at which the trace is
displayed. Increasing the position value of a waveform causes the waveformto
move up. Decreasing the position value causes the waveform to move down. The
minimum is -50 divisions and the maximum is 50 divisions with a resolution
of 0.02 divisions.

Related Commands
RF:RF_PHASe:VERTical:SCAle
Arguments
<NR3> is a floating point number that specifies the vertical position.
Examples
RF:RF_PHASe:VERTical:POSition —1 sets the vertical position of the RF
Phase vs. Time trace to –1 divisi
on.
RF:RF_PHASe:VERTical:POSition? might return 0.0E+0, indicating a
vertical position of 0.
RF:RF_PHASe:VERTical:SCAle
This command specifies the vertical scale for RF Phase vs. Time trace. For a signal
with constant amplitude, increasing the scale causes the waveform to be displayed
smaller. Decreasing the scale causes the waveform to be displayed larger.
Conditions
MDO4000/B/C models only.

Related Commands
RF:RF_PHASe:VERTical:POSition
Arguments
<NR3> is a floating point number that specifies the vertical scale.
Examples
RF:RF_PHASe:VERTical:SCAle 50 sets the vertical scale to 50
degrees/division.
RF:RF_PHASe:VERTical:SCAle? might return 50.0000, indicating that the
vertical scale has been set to 50 degrees/division.

RF:RF_PHASe:
WRAP:DEGrees
Sets or returns the number of degrees to wrap the RF_PHASe time domain trace.
The value can range from –180.0 to 54,000.0 degrees. The default is 360.0
degrees and t

RF:RF_PHASe:WRAP:STATE
Sets or returns the state of the phase wrap control for the RF_PHASE time domain
trace. The default is 1, meaning that wrapping the RF_PHASe time domain
trace is enabled.
