Related Commands
RF:RF_FREQuency:VERTical:SCAle
Arguments
<NR3> is a floating point number.
Examples
RF:RF_FREQuency:VERTical:POSition —1 sets the vertical position of the
RF Frequency vs. Time trace to –1 division.
RF:RF_FREQuency:VERTical:POSition? might return 0.0E+0, indicating a
vertical position of 0.
RF:RF_FREQuency:VERTical:SCAle
This command specifies the vertical scale for the RF Frequency vs. Time tr
ace.
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.

Arguments
<NR3> is a floating point number that specifies the vertical scale.
Examples
RF:RF_FREQuency:VERTical:SCAle 1.0000E+6 sets the vertical scale to
1 MHz/division.

RF:RF_PHASe:LABel
This command specifies the label for the RF Phase vs. Time trace.

RF:RF_PHASe:LABel <QString>
RF:RF_PHASe:LABel?
Related Commands
RF:RF_AMPlitude:LABel, RF:RF_FREQuency:LABel, RF:LABel
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
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

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.
