TWO TONE
AVCC: Analog voltage level, set under Config > Power Supply
(for display purposes only)
DVCC: Digital voltage level, set under Config > Power Supply
(for display purposes only)
Encode: ADC clock rate (MSPS), set under Config > FFT
Analog 1: First analog input frequency (MHz)
Analog 2: Second analog input frequency (MHz)
Fundamental 1: First fundamental tone (dBFS)
Fundamental 2: Second fundamental tone (dBFS)
F1 + F2: Sum of the fundamental tones (dBFS)
F2 – F1: Difference of the fundamental tones (dBFS)
2F1 – F2: 2 × Fundamental 1 – Fundamental 2 (dBFS)
2F1 + F2: 2 × Fundamental 1 + Fundamental 2 (dBFS)
2F2 – F1: 2 × Fundamental 2 – Fundamental 1 (dBFS)
2F2 + F1: 2 × Fundamental 2 + Fundamental 1 (dBFS)
WoIMD: Worst intermodulation distortion (dBc)
IIP2: Measure of the input intercept point in relation to the
second order intermodulation distortion powers (dBm)
IIP3: Measure of the input intercept point in relation to the
third order intermodulation distortion powers (dBm)
SFDR: Spurious-free dynamic range (dBc)
Noise Floor: Level of the noise floor (dBFS)
Samples: Number of samples taken, determined by FFT
configuration, set under Config > FFT
CONTINUOUS TWO TONE
AVERAGE TWO TONE
This function displays a reconstruction of the
captured data in the frequency domain to analyze
dual-tone analog inputs. Several values are listed to
the left of the signal, including
This function displays a continuous dual-tone FFT.
This function displays an average of a user-specified
number of dual-tone FFTs. Configure the number of
FFTs under Config > FFT. The default value is 5.

ZOOMING AND EXPORTING DATA
To zoom in on any portion of a displayed analog signal or FFT,
select the portion of the signal by holding down the left mouse
button and dragging across the area of interest. Bring up a
hidden menu by clicking the right mouse button in the active
window. The hidden menus are slightly different for the time-
domain and FFT plots. These hidden menus have several
options, including zooming and the capability to export time-
domain data. Select from the menus using the left mouse button
(see Figure 7and Figure 8)
H-Zoom: Scales the selected section horizontally
V-Zoom: Scales the selected section vertically
X-Y Zoom: Scales horizontally and vertically (two dimensions)
Exact Zoom: Enter specific coordinates to view
Restore: Restores the graph to its original view
Spawn: Produces an exact working copy of the active window
that can be analyzed separately
Export Data: Writes all of the data points as well as the
calculated information to a file. The information is saved as a
.csv file that can be viewed in Microsoft Excel
Comments: Lets the user enter comments about the graph. If
the FFT is printed, the comments are included in the printout
Lock Data (Time-Domain Plot Only): Once a time-domain
sample of the data is taken, the user can “lock” this data and
then perform an FFT. The FFT will be calculated based on this
data instead of a new sample of data
