n Return Value
frequency)
8 Not used
9 Returns a trace containing the shape of the FFT window
10 Returns trace data of the phase of the FFT versus frequency
11 Returns comma-separated linear spectrum trace data in Volts RMS
12 Returns comma-separated averaged linear spectrum trace data in Volts RMS
13 Returns the following comma-separated scalar results:
1.
I/Q Magnitude and Phase Delta Results available (0 = not available, 1 = available). Results are available
when the last measurement was made with I/Q Magnitude and Phase Delta Results enabled
(:SPEC:IQD:ENAB ON) and the setup was valid for generating the results (invalid setup when input
is I/Q, I/Q Path is I+jQ, and Center Frequency is not 0Hz)
2.
Delta magnitude and phase trace (results 14 – 17) start frequency (0 when I/Q Magnitude and Phase
Delta Results not available)
3.
Delta magnitude and phase trace (results 14 – 17) number of points (1 when I/Q Magnitude and Phase
Delta Results not available)
4.
Delta magnitude and phase trace (results 14 – 17) frequency spacing between points (0 when I/Q
Magnitude and Phase Delta Results not available)
5.
Current average count (1 when I/Q Magnitude and Phase Delta Results not available)
6.
Frequency of the FFT trace (result 4) peak magnitude in Hz (0 when I/Q Magnitude and Phase Delta
Results not available)
7.
Delta magnitude at the FFT trace peak magnitude frequency in dB (-999 when I/Q Magnitude and
Phase Delta Results not available)
8.
Delta phase at the FFT trace peak magnitude frequency in radians (-999 when I/Q Magnitude and
Phase Delta Results not available)
9.
Delta phase at the FFT trace peak magnitude frequency in degrees (-999 when I/Q Magnitude and
Phase Delta Results not available or invalid setup)
10.
Frequency of the averaged FFT trace (result 7) peak magnitude in Hz (0 when I/Q Magnitude and Phase
Delta Results not available)
11.
Averaged delta magnitude at the averaged FFT trace peak magnitude frequency in dB (-999 when I/Q
Magnitude and Phase Delta Results not available)
12.
Averaged delta phase at the averaged FFT trace peak magnitude frequency in radians (-999 when I/Q
Magnitude and Phase Delta Results not available)
13.
Averaged delta phase at the averaged FFT trace peak magnitude frequency in degrees (-999 when I/Q
Magnitude and Phase Delta Results not available)
14 Current delta magnitude trace in dB (-999 when I/Q Magnitude and Phase Delta Results not available)
15 Current delta phase trace in radians (-999 when I/Q Magnitude and Phase Delta Results not available)
