RF:RF_AMPlitu
de:LABel <QString>
RF:RF_AMPlitude:LABel?
Related Commands
RF:RF_FREQuency:LABel, RF:RF_PHASe:LABel, RF:LABel
Arguments
<QString> is a quoted string of up to 32 characters.
RF:RF_AMPlitude:VERTical:POSition
This command specifies the vertical position of the RF Amplitude vs. Time trace.
The position value determines the vertical graticule location at which thetrace
is displayed. Increasing the position value of a waveform causes the waveform
to 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.
Conditions
MDO4000/B/C models only.
Group
RF
Syntax
RF:RF_AMPlitude:VERTical:POSition <NR3>
RF:RF_AMPlitude:VERTical:POSition?
Arguments
<NR3> is a floating point number.
Examples
RF:RF_AMPlitude:VERTical:POSition —1 sets the vertical position of the
RF Amplitude vs. Time trace to -1 division.
RF:RF_AMPlitude:VERTical:POSition? might return 0.0E+0, indicating a
vertical position of 0.
RF:RF_AMPlitude:VERTical:SCAle
This command specifies the vertical scale for the RF Amplitude 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.

Syntax
RF:RF_AMPlitude:VERTical:SCAle <NR3>
RF:RF_AMPlitude:VERTical:SCAle?
Arguments
<NR3> is a floating point number that specifies the vertical scale.
Examples
RF:RF_AMPlitude:VERTical:SCAle 50E-3 sets the vertical scale to
50mV/division.
RF:RF_AMPlitude:VERTical:SCAle? might return 10.0000E-3, indicating
that the vertical scale has been set to 10mV/division.
RF:RF_AVErage:COUNt? (Query Only)
This query returns the number of RF traces that have been accumulated to create
the RF Average frequency domain trace.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:RF_AVErage:COUNt?
Returns
This command returns an integer that ranges from 0 to the number of acquisitions
specified in the command RF:RF_AVErage:NUMAVg.
Examples
RF:RF_AVErage:COUNt? might return 15, indicating that 15 traces have been
accumulated to create the RF Average trace.
RF:RF_AVErage:NUMAVg
This command specifies the number of acquisitions to be used when creating the
RF Average frequency domain trace, which displays the average of values from
multiple acquisitions at each trace point. The range is 2 – 512, in exponential
increments.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

RF:RF_AVErage:NUMAVg?
Related Commands
RF:RF_AVErage:COUNt?
Arguments
<NR1> is an integer.
Examples
RF:RF_AVErage:NUMAVg 100 sets the number of acquisitions to be used for the
RF average trace to 128 (the closest power of 2 increment).
RF:RF_AVErage:NUMAVg? might return 16, indicating that the number of
averages for the RF average trace has been set to 16.
RF:RF_FREQuency:LABel
This command specifies the label for the RF Frequency vs. Time trace.
